Description

Detergents, wetting agents, cleaning agents, foaming agents and dispersants It was found that the polyglycol ethers of aromatic or hydroaromatic oxy compounds, which in the core by at least one hydrocarbon radical or acyl radical with at least q. Carbon atoms are substituted, capillary-active in aqueous solutions or dispersions Effect that they have for use in the most varied branches of technology makes it excellently suited.

The products can be divided according to the length of the polyglycol chain and the resulting degree of water solubility as a wetting agent, as a dispersant, Use emulsifiers, detergents and cleaning agents as well as foam generation agents. Particularly noteworthy is the very good washing effect, which the products on Exercise textiles of all kinds and which one has so far obtained with purely synthetic products could not reach such a degree by far.

Examples of the products to be used according to the invention are Polyglycol ether of p = tert. Butylphenol, isohexylphenol, Isooctylphenol, p-n-dodecylphenol, octadecylphenol; Dodecylnaphthols, isooctylresorcinol, p-oxydiphenyl, o- and p-Benzylphenols, p-Oxybutyrophenone, p-Oxystearophenön, p-Cyclohexylphenol, Isohexylcyclohexanol, isododecylmethylcyclohexanols, etc.

The polyglycol ethers to be used here depend on the length of the polyglycol chain represent oily to solid waxy products. Form with water from milky emulsions to clear solutions. The solutions or emulsions are stable against acids and alkalis as well as against the hardness builders of the water. You can for alone or in a mixture with other textile auxiliaries, with agents which Use bleaching agents to prevent the water hardness builders from precipitating on the fiber and the like can be applied. Examples i. From isooctylphenyl polyglycol ether with a Polyglycol residue consisting of -io mol of glycol is dissolved in 0.5 g in liter of water. A very good washing effect is obtained with cotton. This is increased even more, if you add 0.25 g of soda per liter to the wash liquor.

2. With a solution of q. g isohexylphenyl polyglycol ether with 7 mol Glycol and 1 g of soda per liter of water are made of piece of wool smeared with olive oil .washed. The cleaning effect is excellent.

With the same result can be 1 contains 5 to 17 moles of ethylene oxide which is obtained by the action of ethylene oxide on p-Oxylaurophenon the polyglycol ethers of p-Oxylauroplienons use, and per mole of the ketone approximately.

3. 10 g of a mixture of 95 parts by weight of XYIen01 with 5 parts by weight Isobutylphenyl triglycol ethers contain 30% NaOH per liter of mercerising liquor solved. The mesh and shrink effect on cotton fabric is very good.

d .. i g Isododecylcyclohexylpolyglykolditlier (containing 15 mol glycol) Dissolved in the liter of water gives it to wool and cotton in neutral or soda-alkaline Bathroom has a very good cleaning effect.

5. With a solution of 2 g of p-IsolieXylo-clilorplienylpolyglykoläther with about 7 to 8 mol of glycol and 1/2 g of soda per liter of solution is obtained on wool a very good cleaning effect. .

Instead of the p-isohexyl-o-chlorophenyl polyglycol ether can also other substituted corresponding polyglycol ethers can be used.

6. Cotton laundry is washed in the usual way with a pure solution which contains 0.175 g of isooctyl-o-cresyl polyglycol ether with about 10 glycol residues in the molecule, ig i sodium pyrophosphate and o "2.9 sodium metaphosphate per liter. The cleaning effect is even with heavily soiled laundry outstanding.

; 7. Household laundry is made in a solution containing 10 liters of water about 25 g of crystal soda and 9 g of a dodecylphenyl polyglycol ether with about 12 until i. ¢ contains glycol residues in the molecule. soaked in a known manner. After this Rinse the laundry comes in a wash broth, which per liter o.9 g of the above Dodecylphenylpolyglykolätliers, 5 g crystal soda and i g sodium perborate contains. After the laundry has been brought in, it is slowly heated to a boil for 15 to 20 minutes cooked. Then it is rinsed as usual.

B. i kg of a mixture of 100 g of dry bovine pancreas and goo g of soda and 300 g of isooctylphenyl polyglycol ether, obtained from isooctylphenol and 8 to 10 moles of ethylene oxide, are dissolved in 300 liters of water at from 35 to qo °. With this solution, about 60 kg of dry laundry are washed on the machine for 30 to 10 minutes. The laundry is then rinsed. If desired, you can follow up with another wash cycle with soap or another detergent without added enzymes.

Instead of pancreatic enzymes, enzymes of other origins can also be used, such as those from plants or microorganisms.

G. An isotetradecylphenyl polyglycol ether, the polyglycol ether residue of which consists of 5 moles of ethylene oxide and which is only soluble in water as an emulsion, is an excellent emulsifier for neutral oils: Dissolve 5 g of one such ether in 100 g of machine oil or olive oil and gradually dilute the solution with water. In this way, stable emulsions are obtained.

If you use an isotetradecylphenyl polyglycol ether whose polyglycol ether residue consists of 20 moles of acetylene oxide, it can be used to convert acidic oils, such as olein, into stable, bring finely dispersed emulsion form. Dissolve 3 g of this ether in 100 g of olein and dilute the solution with water or pour the solution into water. Such emulsions are in the most diverse branches of technology as drilling oils, spinning oils, lubricating oils, Spool oils and the like can be used.

ok Normally soiled table linen and underwear are in a bathroom that 3 g of the product of action of 10 moles of ethylene oxide on isooctylphenol in the liter of liquor contains, soaked for several hours at room temperature, rinsed well and then in a wash bath with soap or a synthetic one Detergent like usually washed. By pre-soaking in the manner described above a considerable part of the dirt has already been dissolved out in the cold, so that when subsequent washing process only need to be used in very mild conditions, to get a completely cleaned product.

i i. Soiled kitchen linen is at room temperature in a bathroom, that in the liter of liquor 3 g of the product of action of i i mol of ethylene oxide on isooctylphenyl and 2 g soda calc. contains, soaked overnight and then a usual Subjected to boiling. By using the aforementioned detergent in the soaking bath an excellent pre-cleaning is achieved, so that the whites only require expenditure very small amounts of detergent are required.

12. Underwear made of rayon, rayon, cotton or their blended fabrics is at 30 ° in a bath with 3 g / 1 isododecylphenyl polyglycol ether containing 13 moles of ethylene oxide, with the addition of 2 g of soda calc. and 3 g of sodium perborate such as Usually washed, rinsed and dried. Due to the excellent cleaning power of the detergent mentioned is achieved even under these mild conditions very good cleaning and at the same time very good protection of the fiber material.

13. In 10 parts by weight of the 351% strength aqueous solution of isooctylphenyl polyglycol ether with 6 moles of ethylene oxide, ioo parts by weight of olive oil are gradually stirred in, and the paste thus obtained is slowly diluted with zoo parts by weight of water. In this way, a very stable and finely divided emulsion like her is obtained for example, can be used to melt worsted yarn.

14. 5 parts by weight of the product of action of 5 moles of ethylene oxide on the condensation product of a mixture of isohexylene and isoheptylene with Phenol are dissolved in 100 parts by weight of mineral oil. After stirring in zoo Parts by weight of water is a finely divided emulsion that is necessary for processing of metal parts with cutting tools is well suited. 15. 5 parts by weight of the Product of action of 25 moles of ethylene oxide on 1 mole of isooctylphenol are in ioo Parts by weight of oleic acid dissolved, and the whole is, with stirring, in 300 parts by weight Water entered. The stable and finely divided emulsion obtained is excellent suitable for melting carded yarn material.

16. 100 parts by weight of mineral oil are mixed with 20 parts by weight of the product of 5 moles of ethylene oxide mixed with isooctylphenol and 300 parts by weight in this mixture Stir in water; after adding 50 parts by weight of red iron oxide, one obtains a Extremely durable grinding paste of the water-in-oil type.

17. In a solution of 10 parts isododecylphenyl polyglycol ether with 6 moles of ethylene oxide in 100 parts by weight of petroleum become 20 parts by weight of olein given and then slowly stirred in 40o parts by weight of water.

The emulsion obtained in this way is suitable after the addition of abrasive materials as a polishing agent for metal objects.
