Faste estere kan lett innføres i kom-posisjonene i fast form. Vannuoppløselige faste estere skal imidlertid foreligge i fin-delt tilstand i en fast komposisjon. Solid esters can easily be introduced into the compositions in solid form. However, water-insoluble solid esters must be present in a finely divided state in a solid composition.
Hydrogen peroksyd kan naturligvis ikke innføres i et fast preparat, og bleke-oppløsninger, fremstillet fra hydrogen peroksyd, skal fremstilles for bruk ettersom det kreves. Naturally, hydrogen peroxide cannot be introduced in a solid preparation, and bleaching solutions, made from hydrogen peroxide, must be prepared for use as required.
Hydrogen peroksyd kan tilsettes til oppløsninger som sådant, eller kan frigjø-res på stedet i oppløsningen fra et anorganisk per-salt. Hydrogen peroxide can be added to solutions as such, or can be released in situ in the solution from an inorganic per-salt.
Ved uttrykket «anorganisk per-salt» forståes et salt som vil gi anledning til dannelse av hydrogen peroksyd i vandig oppløsning. Passende forbindelser av al-kalimetallperborater, perkarbonater, per-pyrofosfater og persilikater. Disse er ikke virkelige per-salter i en streng kjemisk forstand, men antas å inneholde bundet hydrogenperoksyd på tilsvarende måte som krystall vann, som frigjøres i vandig opp-løsning. The term "inorganic per-salt" means a salt that will give rise to the formation of hydrogen peroxide in aqueous solution. Suitable compounds of alkali metal perborates, percarbonates, per-pyrophosphates and persilicates. These are not true per-salts in a strict chemical sense, but are believed to contain bound hydrogen peroxide in a similar way to crystal water, which is released in aqueous solution.
Oppfinnelsen kan anvendes på blekebad, f. eks. slike som anvendes for behand-ling av tekstilvarer, til vaskevæsker av den art som anvendes i større vaskerier og i faste blekekomposisjoner. Faste blekekomposisjoner kan inneholde, foruten et per-salt og en ester i henhold til oppfinnelsen, inerte salter, alkaliske midler og en liten mengde av et rensemiddel. Oppfinnelsen kan videre anvendes i forbindelse med rensepreparater som inneholder et organisk rensemiddel, som kan være såpe eller et organisk såpefritt rensemiddel. Passende organiske såpefri rensemidler er alkyl-aryl-sulfonater, alkylsulfater og salter av estere eller etere av isethion-syre. The invention can be applied to bleaching baths, e.g. such as are used for the treatment of textile goods, for washing liquids of the kind used in larger laundries and in fixed bleaching compositions. Solid bleaching compositions may contain, besides a per-salt and an ester according to the invention, inert salts, alkaline agents and a small amount of a cleaning agent. The invention can also be used in connection with cleaning preparations that contain an organic cleaning agent, which can be soap or an organic soap-free cleaning agent. Suitable organic soap-free cleaning agents are alkyl-aryl sulphonates, alkyl sulphates and salts of esters or ethers of isethionic acid.
Preparater i henhold til oppfinnelsen skal fortrinnsvis inneholde en eller flere alkaliske materialer, hvis pH i 0,1 % vandig oppløsning ved 22 °C. er i det minste 9, i mengder som er slik at liknende preparater, som ikke inneholder estere, vil ha en pH-verdi innenfor området 9—11 når de oppløses ved den ønskete blekekonsen-trasjon, og fremgangsmåten ifølge oppfinnelsen anvendes fortrinnsvis vandige opp-løsninger som inneholder slike alkaliske materialer. De fleste vanlige rensemiddel-komposisjoner inneholder alkaliske materialer i en mengde som er tilstrekkelig for dette øyemed. Skikkete alkaliske materialer er f. eks. såpe, alkalimetallkarbona-ter, fosfater (innbefattet ortofosfater og vannoppløselige kondenserte fosfater, som f. eks. tripolyfosfater og pyrofosfater) og silikater. Preparations according to the invention should preferably contain one or more alkaline materials, the pH of which in a 0.1% aqueous solution at 22 °C. is at least 9, in amounts that are such that similar preparations, which do not contain esters, will have a pH value in the range 9-11 when dissolved at the desired bleach concentration, and the method according to the invention is preferably used in aqueous solutions solutions containing such alkaline materials. Most common detergent compositions contain alkaline materials in an amount sufficient for this purpose. Suitable alkaline materials are e.g. soap, alkali metal carbonates, phosphates (including orthophosphates and water-soluble condensed phosphates, such as tripolyphosphates and pyrophosphates) and silicates.
Når bleke- eller vaskevæsker anvendes i henhold til fremgangsmåten ifølge oppfinnelsen skal der fortrinnsvis være tilstede tilstrekkelig alkalisk material for å gi en utgangs-pH9—11 i bleke- eller vaske-væsken før tilsetningen av esteren. When bleaching or washing liquids are used according to the method according to the invention, sufficient alkaline material must preferably be present to give an initial pH of 9-11 in the bleaching or washing liquid before the addition of the ester.
Preparater i henhold til oppfinnelsen kan inneholde hvilke som helst av de vanlige tilsetningsmidler som er tilstede i rensemiddelpreparater. Der skal nevnes supplementerende «builders», inerte og organiske materialer, som f. eks. alkali-metallsulfater, klorider, karboksymetylcel-lulose og fluoriserende midler. Preparations according to the invention can contain any of the usual additives that are present in cleaning agent preparations. Mention must be made of supplementary "builders", inert and organic materials, such as e.g. alkali metal sulphates, chlorides, carboxymethyl cellulose and fluorescent agents.
Preparater i henhold til oppfinnelsen må ikke inneholde vann i en mengde som er tilstrekkelig til å tillate en nevneverdig kjemisk reaksjon mellom komponentene før bruken. Preparations according to the invention must not contain water in an amount sufficient to allow a significant chemical reaction between the components before use.
Mengden av per-salt og ester som kan være tilstede i preparatet i henhold til oppfinnelsen vil bero på tiden og temperaturen ved blekingen, den grad av bleking som kreves, konsentrasjonen av blekeopp-løsningen og den spesielle ester og per-salt som anvendes. Under de fleste forhold skal disse mengder være slik at man får en per-salt-konsentrasjon i oppløsningen, svarende til 0,001 til 0,1 % tilgjengelig oxygen. The amount of per-salt and ester which may be present in the preparation according to the invention will depend on the time and temperature of the bleaching, the degree of bleaching required, the concentration of the bleaching solution and the particular ester and per-salt used. Under most conditions, these quantities should be such that a per-salt concentration is obtained in the solution, corresponding to 0.001 to 0.1% available oxygen.
Idet der tas i betraktning disse fak-torer kan der oppnåes blekeeffekter med preparater ifølge oppfinnelsen, som inneholder sterkt varierende forhold av per-salt til esteren. Det er hensiktsmessig å måle aktiviteten av per-saltet uttrykt i form av tilgjengelig oxygen. Generelt fore-trekkes forhold av fra Vi—2, og særlig fra <y>%—iy2 molekyler ester for hvert atom tilgjengelig oksygen for anvendelse ved fremgangsmåten og preparatene ifølge oppfinnelsen. (Ved omregning av slike forhold til vektsforhold må man ta i betraktning mo-lekylarvekten av esteren og det tilgjengelige oxygeninnhold i det anvendte per-salt). Særlig er det å foretrekke å an-vende omtrentlig kjemisk ekvivalente mengder av esteren og per-saltet. Ved fastsettelsen av slike kjemiske ekvivalente mengder må man være oppmerksom på at med estere, som inneholder mere enn en estergruppe, vil ikke nødvendigvis alle estergrupper reagere med tilgjengelig sur-stoff i per-saltet. Med aldehyddiacetater antas således bare en gruppe å reagere, med glykosetetraacetat reagerer en gruppe og med glykosepentaacetat reagerer to grupper. Taking these factors into account, bleaching effects can be achieved with preparations according to the invention, which contain highly varying ratios of per-salt to the ester. It is appropriate to measure the activity of the per-salt expressed in terms of available oxygen. In general, a ratio of from Vi to 2, and in particular from <y>% to iy2 molecules of ester for each available oxygen atom is preferred for use in the method and preparations according to the invention. (When converting such ratios to weight ratios, one must take into account the molecular weight of the ester and the available oxygen content in the per-salt used). In particular, it is preferable to use approximately chemically equivalent amounts of the ester and the per-salt. When determining such chemical equivalent amounts, one must be aware that with esters, which contain more than one ester group, not all ester groups will necessarily react with available oxygen in the per-salt. Thus, with aldehyde diacetates only one group is assumed to react, with glucose tetraacetate one group reacts and with glycosepentaacetate two groups react.
Når der anvendes oppløsninger, som fåes ved tilsetning av vannstoffperoksyd og en ester i henhold til oppfinnelsen til et alkalisk bad, er det foretrukne vektsforhold fra 2—15 deler av en ester til en del av hydrogen-peroksyd (100 %), be-roende på molekylvekten av den anvendte ester. When solutions are used, which are obtained by adding hydrogen peroxide and an ester according to the invention to an alkaline bath, the preferred weight ratio is from 2-15 parts of an ester to one part of hydrogen peroxide (100%), depending on the molecular weight of the ester used.
Når preparater i henhold til oppfinnelsen skal anvendes primært som et bleke-middel, f. eks. for tilsetning til alkalisk tekstilblekebad eller vaskevæsker, kan slike preparater inneholde en hvilken som helst mengde av en ester og per-salt, og disse komponenter bør fortrinnsvis være tilstede i forholdet Vi—2 molekyler ester for hvert atom tilgjengelig oxygen, og fortrinnsvis y2 til iy> molekyler for hvert atom tilgjengelig oxygen. Som eksempel skal således nevnes at en komposisjon kan inneholde 33 % av per-salt med 10 % tilgjengelig oxygen og 67 % av benzoylesteren av handelsnatriumfenolsulfat. Anvendes per-salter med 15 % tilgjengelig oxygen kan komposisjonen inneholde 25 % av per-saltet og 75 % av benzoylesteren av handels-natriumfenolsulfonat. When preparations according to the invention are to be used primarily as a bleaching agent, e.g. for addition to alkaline textile bleaching baths or washing liquids, such preparations may contain any amount of an ester and per-salt, and these components should preferably be present in the ratio Vi to 2 molecules of ester for each atom of available oxygen, and preferably y2 to iy > molecules for each atom of available oxygen. As an example, it should thus be mentioned that a composition may contain 33% of per-salt with 10% available oxygen and 67% of the benzoyl ester of commercial sodium phenol sulfate. If per-salts with 15% available oxygen are used, the composition can contain 25% of the per-salt and 75% of the benzoyl ester of commercial sodium phenol sulphonate.
Når et organisk rensemiddel er tilstede i komposisjoner i henhold til oppfinnelsen kan der oppnåes forbedringer ved blekingen ved vanlige vaskekonsentra-sjoner. Anvendes der f. eks. en rensemid-delkomposisjon i henhold til oppfinnelsen ved en konsentrasjon av 1 % i vandig; opp-løsning kan der oppnåes forbedringer, hvis der er tilstede mengder av så lite som 1 % per-salt og 2 % ester basert på vekten av komposisjonen. I slike komposisjoner skal imidlertid mengden av per-salt tilveiebringe minst 0,1 % tilgjengelig oxygen, basert på komposisjonen. Generelt vil rensemiddelpreparater inneholde fra ca. 10 til ca. 50 vektsprosent av det organiske rensemiddel. Det blandete ester/per-salt-inn-hold kan være så høyt som 70 vektsprosent, forutsatt at disse komponenter anvendes i forholdet <y>4—2, fortrinnsvis <y>2 —iy2 molekyler av ester pr. ett atom tilgjengelig oxygen. Effektiv mengder av ester og per-salt i rensemiddel og andre preparater vil i alminnelighet ligge innenfor områder av fra 2—30 % ester og 1—15 % per-salt, basert på komposisjo-nens vekt. When an organic cleaning agent is present in compositions according to the invention, improvements can be achieved in the bleaching at normal washing concentrations. Used where e.g. a cleaning agent composition according to the invention at a concentration of 1% in water; solution, improvements can be achieved if amounts of as little as 1% per-salt and 2% ester based on the weight of the composition are present. In such compositions, however, the amount of per-salt should provide at least 0.1% available oxygen, based on the composition. In general, cleaning agent preparations will contain from approx. 10 to approx. 50% by weight of the organic cleaning agent. The mixed ester/per-salt content can be as high as 70% by weight, provided that these components are used in the ratio <y>4-2, preferably <y>2 -iy2 molecules of ester per one atom of available oxygen. Effective amounts of ester and per-salt in cleaning agents and other preparations will generally lie within ranges of from 2-30% ester and 1-15% per-salt, based on the weight of the composition.
De beste resultater ved bleking i henhold til oppfinnelsen oppnåes under forhold hvor der bevirkes en effektiv om-røring, som f. eks. vil foreligge i en vaske-maskin. The best results in bleaching according to the invention are achieved under conditions where effective stirring is effected, such as e.g. will be available in a washing machine.
De følgende eksempler vil tjene til å klargjøre oppfinnelsen: The following examples will serve to clarify the invention:

Et stykke av et bomullstøy ble flekket ved neddykking i kokende te-ekstrakt i en time. Derpå ble tøyet omhyggelig skyllet,, tørket og skåret til prøvestykker, og ref leks jonsprosenten ble målt i en Hunter-reflektometer under anvendelse av et blå-filter. Refleksjonsprosenten til prøvestyk-kene ble påny målt etter bleking. Den oppnådde bleking ble uttrykt som forskjel-len mellom de to målte refleksjonsprosen-ter på hvert prøvestykke. A piece of cotton cloth was stained by immersion in boiling tea extract for one hour. The cloth was then carefully rinsed, dried and cut into test pieces, and the reflect ion percentage was measured in a Hunter reflectometer using a blue filter. The reflectance percentage of the test pieces was measured again after bleaching. The bleaching achieved was expressed as the difference between the two measured reflection percentages on each sample.
Et stykke av et te-flekket bomullstøy ble neddykket i blekebadet med et forhold mellom tøystykket og væsken som 1 : 20, og der ble omrørt i 15 minutter, og temperaturen ble holdt ved 60 + 2°C. Etter forløpet av denne tid ble tøystykket skylt tre ganger, strøket og refleksjonsprosenten ble målt-. Økningen i refleksjonsprosenten var 22,7. Ved et liknende kontrollforsøk, som ble utført i fravær av kloraldiacetat, var økningen i prosentrefleksjonen bare 13,7. A piece of a tea-stained cotton cloth was immersed in the bleach bath with a ratio of the cloth to the liquid as 1 : 20, and was stirred for 15 minutes, and the temperature was maintained at 60 + 2°C. After this time, the piece of cloth was rinsed three times, ironed and the reflectance percentage was measured. The increase in the reflection percentage was 22.7. In a similar control experiment, which was carried out in the absence of chloral diacetate, the increase in the percentage reflection was only 13.7.

Tøystykket ble derpå skyllet tre ganger, strøket og refleksjonsprosenten ble målt. Økningen i prosentref leksjonen var 19,0. Ved et kontrollforsøk uten gly-kose-penta-acetat var økningen i prosentrefleksjonen bare 13,2. A 0.5% solution of the finished preparation was prepared at 60 °C. and a piece of cloth, stained with tea, and prepared as described in Example 1, was immersed in the solution and stirred for 15 minutes, and the temperature was maintained at 60°C.+ 2°C. The garment was then rinsed three times, ironed and the reflectance percentage was measured. The increase in percentage reflection was 19.0. In a control experiment without glucose-penta-acetate, the increase in the percentage reflection was only 13.2.
