Process for the production of fatty ketones

A process for the isolation and purification of essentially fatty acid mixtures, which in addition to the methyl branched fatty acids contain saturated and unsaturated, respectively straight chain as well as methyl branched, unsaturated fatty acids, in which the industrial fatty acid mixtures are first hydrogenated by catalysis and then the methyl branched saturated fatty acids are separated, and in which before the hydrogenation if necessary, a separation by the hydrophilization process is provided, this process produces the desired products with a high yield and purity.

Process for the recovery of methyl-branched, saturated C.sub.14 -C.sub.24 -

Quaternary ammonium compounds containing one or two long-chain ester or amide radicals of etherified hydroxycarboxylic acids and, for the remainder, short-chain radicals, which are liquid to pasty substances that may readily be dissolved or dispersed in water or alcohol/water mixtures. They may be used in dilute or concentrated, storable form for softening fabrics without the absorbency of the treated fabrics being adversely affected. The quaternary ammonium compounds are obtained by reaction of epoxyfatty acid esters with amines and subsequent quaternization.

This invention is directed to the preparation of .alpha.-sulfofatty acid esters. More particularly, this invention is directed to a process for the simplified preparation of light-colored, wash-active esters of .alpha.-sulfofatty acids with monovalent C.sub.1 to C.sub.8 alcohols or their salts from fats and oils of vegetable and/or animal origin comprising re-esterification with the monovalent alcohols or saponification and esterification with the monovalent alcohols, separation of the fatty acid ester formed, hydrogenation of the fatty acid ester, sulfonation, and bleaching, wherein a fatty acid ester fraction from which accompanying fatty acid glycerides have been removed to the extent of about 1 percent by weight or less, based upon the weight of the material to be sulfonated, is introduced into the sulfonation stage.

Preparation of light-colored, wash active .alpha.-sulfofatty acid

Lower alkyl esters of higher fatty acids with improved processing properties, particularly sulfonation, are obtained by subjecting lower alkyl esters of higher fatty acids of plant and/or animal origin, or said fatty acids per se, in the presence of esterification catalysts and/or carboxylic acid anhydrides, to a brief temperature treatment above 150.degree. C., and separating simultaneously and/or subsequently, preferably by distillation, the purified lower alkyl esters of higher fatty acids or the purified higher fatty acids from the treated material and the purified higher fatty acids are then esterified with lower alkanols.

The present invention is for a process for the preparation of alkali metal salts of acyl cyanamides, especially those of aliphatic carboxylic acids by reacting carboxylic acid esters of lower alcohols with monoalkali metal cyanamides. The reaction results in a process which is simple and efficient and one which can be used in commercial scale batch or continuous operations.

A continuous process for the bleaching of acid .alpha.-sulfo-fatty acid esters of predominantly C.sub.16-24 fatty acids comprising continuously adding the hydrogen peroxide bleach in aqueous solution as well as from 2% to 50% by weight, based on the sulfonated esters, of a C.sub.6-18 alkylbenzene sulfonic acid, to said raw, acid .alpha.-sulfo-fatty acid esters at a temperature of 40.degree. to 65.degree. C, continuously passing said mixture through a confined zone of dimensions sufficient to give a proper bleach retention time and continuously recovering bleached .alpha.-sulfo-fatty acid esters.

Process and agent for fatting or lubrication of leather and furs based on the salts of sulfonated chlorinated products of higher fatty acids or of esters of higher fatty acids, said fatty acids having from 8 to 24 carbon atoms, especially natural fats and oils or tallow fatty acid methyl ester, having a chlorine content of 20% to 45% by weight and essentially free of olefinic double bonds and having an SO.sub.3 content of from 40 to 150 mol percent based on the chlorinated product, which agent and the leather and furs so treated are extraordinarily resistant to the effect of light, to oxidation and to acids.
