A process for waterproofing leather and skins with a silicone oil and the salt of an N-(C.sub.9 -C.sub.20 -acyl)-amino acid as an emulsifier for the silicone oil, which is carried out in the aqueous phase during or after retanning, and the use of salts of N-acylamino acids as emulsifiers for silicone oils in the waterproofing of leather and skins in the aqueous phase, and the mixtures used for this purpose.

Waterproofing leather and skins

Acyloxybenzenesulfonic acids and their alkali metal and alkaline earth metal salts are prepared by a process comprising sulfonation of a phenyl ester in the presence or absence of a small amount of a complexing agent for the sulfonating agent SO.sub.3 or chlorosulfonic acid, subsequent acylation and, if desired, neutralization to give the alkali metal or alkaline earth metal salt, and, if required, subjecting the latter to oxidative bleaching before drying.

Alkali metal and alkaline earth metal salts of acyloxybenzenesulfonic acids of the formula I ##STR1## where R is a saturated or unsaturated alkyl radical of 1 to 17 carbon atoms or is phenyl which is unsubstituted or monosubstituted or disubstituted by alkyl of 1 to 3 carbon atoms, halogen, methoxy or nitro, are prepared by neutralization, by a method in which a liquid acyloxybenzenesulfonic acid of the formula I and an aqueous solution of an alkali metal or alkaline earth metal hydroxide, carbonate or bicarbonate are combined in water, at from 0.degree. to 60.degree. C. and while mixing thoroughly, so that the pH is kept at from 2.5 to 7.0, and, if desired, the resulting salt is isolated from the aqueous solution in a conventional manner.

The subject invention relates to the use of foam inhibitors in printing pastes based on oil-in-water emulsions or aqueous emulsions. The foam inhibitors are mixtures of monoalkyphosphates and aliphatic esters or high boiling hydrocarbons.

Printing pastes with foam inhibitors

A process for purifying C.sub.8 -C.sub.16 -alkylglycosides which have been obtained by reacting lower alkylglycosides or hydroxyalkylglycosides with C.sub.8 -C.sub.16 -alcohols in the presence of an acid catalyst, by distillative removal of unconverted C.sub.8 -C.sub.16 -alcohols, wherein the distillative removal, at least of the last amounts of unconverted alcohols, is carried out in the presence of glycols whose boiling points are at most 10.degree. above, and at most 30.degree. below, those of the alcohols to be removed.

Alkanes substituted by chlorine atoms and/or sulfochloride groups are prepared by reacting alkanes with chlorine, with or without sulfur dioxide, in a particular throughput ratio, in a reaction chamber inclined to the horizontal, the starting materials being passed through the reaction chamber in co-current, from below. The substituted alkanes or paraffins obtainable by the process of the invention are pesticides, plasticizers, solvents and starting materials for the preparation of such products, as well as of fat liquors, detergents, lubricating oils, synthetic resins and slip agents.
