Description
7712179-6 na en vattenolöslig, organisk förening såsom olja, fett eller vax samt att återvinna densamma genom att man bildar en emul- sion av den vattenolösliga, organiska föreningen i vatten med hjälp av en ytaktiv förening, att man bryter emulsionen i en organisk fas och en vattenfas och att man separerar den orga- niska fasen från vattenfasen, varvid sättet utmärks av att den f ytaktiva föreningen, som man tillsätter, utgörs av ett eterfos- fat med den allmänna formeln ' RIO \\+\ P lIl,,OH R- (znn-o/ \0 där R är en kolvätegrupp om 8-30 kolatomer, varje A betecknar en grupp härledd från en alkylenoxid med 2-3 kolatomer, n är ett helt tal 1-30 och Rl betecknar väte eller gruppen R-(A)n, där A, R och n har ovan angivna betydelser, och att man bryter emulsionen genom att man inställer dess pH-värde på 7-10. Fö- redragna eterfosfat är sådana, där R är en kolvätegrupp om 10- -24 kolatomer, A betecknar en oxialkylengrupp, som till minst 10 % av sitt antal är härledd från etylenoxid, och n är ett tal 2-20. A water-insoluble organic compound such as oil, fat or wax and to recover it by forming an emulsion of the water-insoluble organic compound in water by means of a surfactant compound, breaking the emulsion into an organic phase and an aqueous phase and separating the organic phase from the aqueous phase, the method being characterized in that the surfactant compound which is added consists of an ether phosphate of the general formula 'R10 \\ + \ P lIl ,, OH R- (znn-o / \ 0 where R is a hydrocarbon group of 8-30 carbon atoms, each A represents a group derived from an alkylene oxide having 2-3 carbon atoms, n is an integer 1-30 and R 1 represents hydrogen or the group R - (A) n, where A, R and n have the meanings given above, and breaking the emulsion by adjusting its pH to 7-10, Preferred ether phosphates are those in which R is a hydrocarbon group of 10- -24 carbon atoms, A represents an oxyalkylene group, which at least 10% of its number is derived from ethylene oxide, and n is a number 2-20.
Vid tillämpning av uppfinningen erhåller man genom att använda ifrågavarande eterfosfat som emulgator dels en förhållandevis snabb och lätt emulsionsbildning, dels en emulsion med god sta- bilitet; När emulsionen neutraliseras med en konventionell vat- tenlöslig bas och erhåller ett pH-värde av ca 7-10 brytes emul- 'sionen likaledes snabbt och effektivt på grund av den dåliga emulgerande förmågan hos eterfosfatsaltet. Av stor betydelse är att syraformens emulgerande förmåga till skillnad från ett fler- tal andra emulgatorer icke i nämnvärd utsträckning påverkas ne- gativt av vattnets elektrolythalt eller andra föroreningar. Det- 7712179-6 ta betyder att mycket hårt vatten, t.ex. med en hårdhet av minst 50 dH°, såsom bräckt vatten och saltvatten, med fördel kan användas.When applying the invention, by using the ether phosphate in question as emulsifier, a relatively fast and easy emulsion formation is obtained, on the one hand, and an emulsion with good stability; When the emulsion is neutralized with a conventional water-soluble base and reaches a pH of about 7-10, the emulsion is also broken down quickly and efficiently due to the poor emulsifying ability of the ether phosphate salt. Of great importance is that the emulsifying ability of the acid form, unlike a number of other emulsifiers, is not significantly affected by the electrolyte content of the water or other pollutants. This means that very hard water, e.g. with a hardness of at least 50 dH °, such as brackish water and brine, can be used to advantage.
Vid tillämpning av uppfinningen kan eterfosfatet antingen«blan- das direkt med det vatten, varmed den olösliga, organiska för- eningen skall emulgeras eller sättas, företrädesvis löst i ett organiskt lösningsmedel, till den vattenolösliga organiska för- eningen, innan denna emulgeras i vattnet. Mängden eterfosfat är icke kritisk, utan den kan variera inom vida gränser. Av prak- tiska och ekonomiska skäl användes dock i regel l-100 g/kg av den vattenolösliga, organiska förening, som skall behandlas.In the practice of the invention, the ether phosphate may either be mixed directly with the water with which the insoluble organic compound is to be emulsified or added, preferably dissolved in an organic solvent, to the water-insoluble organic compound, before it is emulsified in the water. The amount of ether phosphate is not critical, but it can vary widely. For practical and economic reasons, however, l-100 g / kg of the water-insoluble organic compound to be treated is generally used.
Det organiska lösningsmedlet är konventionellt och kan bl.a. ut- göras av alifatiska eller aromatiska kolväten; alkyletrar, så- som butyldietylenglykol eller etyletylenglykol; och kortkedjiga alkoholer, såsom hexanol, butanol eller isopropanol; eller blandningar av desamma. Halten eterfosfat i det organiska lös- ninqimadlat är vanligtvis 1-50 viktpæeøsnt.The organic solvent is conventional and can e.g. consists of aliphatic or aromatic hydrocarbons; alkyl ethers, such as butyl diethylene glycol or ethyl ethylene glycol; and short chain alcohols such as hexanol, butanol or isopropanol; or mixtures thereof. The ether phosphate content of the organic solution is usually 1-50% by weight.
De enligt uppfinningen använda fosfatestrarna kan framställas på känt sätt genom fosfatering av alkylenoxidaddukter med den allmänna formeln R(A)nOH, där R, A och n har den ovan angivna betydelsen. Vid fosfateringsförfarandet bildas både mono- och disubstituerade eterfosfat. På grund av bättre löslighets- och emulgeringsegenskaper föredrages i regel att merparten av eter- fosfatet utgöres av monoföreningen, dvs. att Rl i minst 50 % av fallen är väte. Det bör dock uppmärksammas att även kolvätegrup- pens storlek och oxialkylenkedjans längd påverkar löslighets- och emulgeringsegenskapen, vilket bl.a. innebär att disubstitue- rade eterfosfat med förhållandevis liten kolvätegrupp och/el- ler förhållandevis lång oxialkylenkedja med fördel kan användas enligt uppfinningen.The phosphate esters used according to the invention can be prepared in a known manner by phosphating alkylene oxide adducts of the general formula R (A) nOH, where R, A and n have the meaning given above. In the phosphating process, both mono- and disubstituted ether phosphates are formed. Due to better solubility and emulsifying properties, it is generally preferred that the majority of the ether phosphate consists of the mono compound, ie. that R1 in at least 50% of cases is hydrogen. However, it should be noted that the size of the hydrocarbon group and the length of the oxyalkylene chain also affect the solubility and emulsification property, which i.a. means that disubstituted ether phosphates with a relatively small hydrocarbon group and / or a relatively long oxyalkylene chain can be used to advantage according to the invention.
Exempel på lämpliga eterfosfat är etylenoxidaddukter av alkyl- substituerade fenoler, såsom nonylfenol med 2-10 mol etylenoxid, dinonylfenol med 4-20 mol etylenoxid, oktylfenol med 2-10 mol etylenoxid, oktylkresol med 3-15 mol etylenoxid, tri-sek.-butyl- fenol med 2-10 mol etylenoxid. 7712179-6 Andra lämpliga föreningar är etylenoxidaddukter av alifatiska alkoholer, såsom oleylalkohol med 3-15 mol etylenoxid, laur- ylalkohol med 2-l0 mol etylenoxid, tridecylalkohol med 2-10 mol etylenoxid, cetylalkohol med 3-l5 mol etylenoxid, stearyl- alkohol med 3-15 mol etylenoxid.Examples of suitable ether phosphates are ethylene oxide adducts of alkyl-substituted phenols, such as nonylphenol with 2-10 moles of ethylene oxide, dinonylphenol with 4-20 moles of ethylene oxide, octylphenol with 2-10 moles of ethylene oxide, octylcresol with 3-15 moles of ethylene oxide, tri-sec. butylphenol with 2-10 moles of ethylene oxide. Other suitable compounds are ethylene oxide adducts of aliphatic alcohols, such as oleyl alcohol with 3-15 moles of ethylene oxide, lauryl alcohol with 2 to 10 moles of ethylene oxide, tridecyl alcohol with 2-10 moles of ethylene oxide, cetyl alcohol with 3 to 10 moles of ethylene oxide, with 3-15 moles of ethylene oxide.
Den vid vattenbegjutningen erhållna emulsionen har normalt ett pH-värde av 2-4. Vid brytningen av emulsionen tillsättes en konventionell bas i sådan mängd att ett pH-värde av 7-10 erhål- les. Vid pH-värden under 7 erhålles en jämförelsevis långsam och ofullständig brytning och denna tendens ökar snabbt med av- tagande pH-värde. Å andra sidan är pH-värden över 10 olämpliga, beroende dels pâ en ökad kemikalieåtgång, dels på en flockule- ring i oljefasen. Om så önskas kan brytningen av emulsionen på- skyndas genom att man tillsätter vattenlösliga salter av två- värda katjoner, såsom vattenlösliga kalcium- och magnesiumsal- ter. Mängden salt är lämpligen 0,2-5 g/kg emulsion.The emulsion obtained during the water spraying normally has a pH value of 2-4. When breaking the emulsion, a conventional base is added in such an amount that a pH value of 7-10 is obtained. At pH values below 7, a comparatively slow and incomplete refraction is obtained and this tendency increases rapidly with decreasing pH value. On the other hand, pH values above 10 are unsuitable, partly due to increased chemical consumption and partly to a flocculation in the oil phase. If desired, the breaking of the emulsion can be accelerated by adding water-soluble salts of divalent cations, such as water-soluble calcium and magnesium salts. The amount of salt is suitably 0.2-5 g / kg of emulsion.
Exempel på lämpliga baser är hydroxider av alkalimetaller, såsom hydroxider av kalium och natrium, hydroxider av jordalkalimetal- ler, såsom hydroxider av magnesium och kalcium, ammoniak och karbonater, såsom natrium- och kaliumkarbonat. Ytterligare ex- empel är organiska baser, såsom primära, sekundära och kvater- nära ammoniumföreningar.

Föreliggande uppfinning åskådliggöres ytterligare av nedanståen- de utföringsexempel.The present invention is further illustrated by the following embodiments.
Exempel 1 - 6 Till en skakcylinder sattes 5 g av en olja (Eldningsolja nr. 3). 0,25 g av ett eterfosfat, som till ca 75 % utgjordes av ett mo- o noeterfosfat, löstes i l g av ett alifatiskt lösningsmedel (Ny- solvin 75 A) och det hela droppades på oljan. Slutligen tillsat- tes 95 ml syntetiskt havsvatten, vilket innehöll 0,6 g MgCl2, 0,1 g CaCl2, 0,4 g Na2S04 och 2,5 g NaCl, varefter skakcylindern 7712179-6 vändes 10 ggr på ca 20 sek. Den erhållna emulsionen bedömdes visuellt efter skalan utmärkt, god, måttlig och dålig emulsion.Examples 1 - 6 To a shaking cylinder was added 5 g of an oil (Fuel Oil No. 3). 0.25 g of an ether phosphate, which was about 75% a monoether phosphate, was dissolved in 1 g of an aliphatic solvent (Ny-solvin 75 A) and the whole was dripped onto the oil. Finally, 95 ml of synthetic seawater was added, which contained 0.6 g of MgCl 2, 0.1 g of CaCl 2, 0.4 g of Na 2 SO 4 and 2.5 g of NaCl, after which the shaker cylinder 7712179-6 was inverted 10 times in about 20 seconds. The resulting emulsion was visually judged by the scale to be excellent, good, moderate and poor emulsion.
Därefter försattes emulsionen med en bas, och tillsatsens in- verkan på emulsionens brytning bedömdes visuellt efter ca 5 min. Bedömningsskalan var utmärkt, god, måttlig och dålig bryt- ning. Resultaten framgår av nedanstående tabell, ur vilken kan läsas att samtliga provade eterfosfat hade en emulgeringsförmå- ga, som var utmärkt eller god. Brytningsförmågan var i samtliga fall, utom när'basernakalciumhydroxid och monoetanolamin använ- des, god eller utmärkt. Det mindre goda men ändock godtagbara resultatet för kalciumhydroxid och monoetanolamin förklaras av att pH-värdet i dessa fall inställdes på 7,2 och 7,5.Then the emulsion was added with a base, and the effect of the additive on the breaking of the emulsion was assessed visually after about 5 minutes. The assessment scale was excellent, good, moderate and poor refraction. The results are shown in the table below, from which it can be read that all the ether phosphates tested had an emulsifying ability, which was excellent or good. The refractive power was good or excellent in all cases, except when the bases calcium hydroxide and monoethanolamine were used. The less good but still acceptable result for calcium hydroxide and monoethanolamine is explained by the fact that the pH value in these cases was adjusted to 7.2 and 7.5.
Exempel 7 Till en skakcylinder sattes 5 g av en olja (Eldningsolja nr 3). blattar tilllaatan 95 m1 nyntetinkt havsvatten, vari lagts 0,5 g av eterfosfatet i Exempel l, dvs. en fosfaterad alkylen- oxidaddukt av Cl2_l4-alkyl och 3 mol etylenoxid. Det syntetiska havsvattnet var av samma slag som i tidigare exempel. Skakcy- lindern vändes därefter 10 gånger på ca 20 sekunder och den er- hållna emulsionen bedömdes visuellt enligt samma skala som i ti- digare försök. Slutligen tillsattes natriumhydroxid till ett pH 'av 9,0. Efter 5 min. bedömdes brytningens effektivitet enligt samma_skala som i Exempel l - 6. Resultatet framgår av tabellen och ger vid handen att oavsett om eterfosfatet upplöses i ett organiskt lösningsmedel (Exempel l) eller löses direkt i vatten ' erhålles med förfarandet enligt uppfinningen såväl en utmärkt emulsion som en utmärkt brytning av emulsionen.Example 7 To a shaking cylinder was added 5 g of an oil (Fuel Oil No. 3). leaves allow 95 ml of fresh seawater, in which 0.5 g of the ether phosphate in Example 1 is added, i.e. a phosphated alkylene oxide adduct of C 12-14 alkyl and 3 moles of ethylene oxide. The synthetic seawater was of the same type as in previous examples. The shaking cylinder was then inverted 10 times in about 20 seconds and the resulting emulsion was visually assessed according to the same scale as in previous experiments. Finally, sodium hydroxide was added to a pH 'of 9.0. After 5 min. The efficiency of the refraction was assessed according to the same scale as in Examples 1 to 6. The result is shown in the table and suggests that regardless of whether the ether phosphate is dissolved in an organic solvent (Example 1) or dissolved directly in water, the process of the invention excellent breaking of the emulsion.
Exempel 8 Till en skakcylinder sattes 5 g av en olja (Eldningsolja nr 3). 0,25 g av ett etersulfat, som till ca 75 % utgjordes av ett mo-- noeterfosfat, löstes i l g isopropanol och det hela droppades 7712179-6 på oljan. Slutligen tillsattes 95 ml syntetiskt havsvatten av samma slag som i tidigare exempel och skakcylindern vändes 10 gånger på ca 20 minuter. Den erhållna emulsionen bedömdes på samma sätt som tidigare. Därefter försattes emulsionen med natriumhydroxid till ett pH av 8,7 och pH~förändringens inver- kan på emulsionens brytning bedömdes visuellt efter ca 5 min. efter samma skala som tidigare. Det erhållna resultatet, som framgår av tabellen, visar att även fosfaterade propylenoxidad- dukter med fördel kan användas enligt föreliggande uppfinning. 7712179-6 _uxHwE»n >.w wfiwouwwnaøfluumz wow ~\| Hwxflmncflu. w uxuwspo o.m wfixouømnænwuumz. uxuweua |\m H>xHm|«H|~Hu ß »x»wa»s m.m wfixouwwaaøfiuumz wow . |\w Hwnwuflwnønfia w uxumEuD må flfiwouwæfišfiuumz wow |\w .fihnwuflhnøz m uxnwavn m.m wflxo»w>neø«u»mz uxuwauo |\« H>Mflm|wHu ~. uxuweuø °.m wfixouwwnaøfiuumz uxuwsva .=näaflHv~\« H>xHm|«H|~Ho m uxwmævø m.m u«xouw>nss«H»mz «H|~H wow °.m xmflnoaam wow . |\- H»xH~| u N mflauvmä m _ h QwEmHOGNMwOQOE mfiufiws ~§ uflxouwmåšwofimx uxumavø m.w uflxouwwaeøflflmm uxuwaaø m.m uflxouwmnaøwuuøz vfiuwfi wow >.w Mmfinøeaæ uxuwsuø |\m H»xHø| u a _ wflxonwflhmonm . .mmmñumwwmnflcuwum mm mmm mmwšuwummnflnmmfløëm Äåxoamflhflw Hoë m . . uøwnomuwvm .fimmämxm HHwÄNH.Example 8 To a shaking cylinder was added 5 g of an oil (Fuel Oil No. 3). 0.25 g of an ether sulphate, which was about 75% a monoether phosphate, was dissolved in 1 g of isopropanol and the whole was dropped on the oil.
