Abstract: Preparation of the trisodium salt of isoserine-N,N-diacetic acid (I) by reaction of acrylonitrile with aqueous hydrogen peroxide to give glycidamide (II) and further reaction of II with the disodium salt of iminodiacetic acid (III) to give I, by carrying out the process continuously and, in it, successively a) reacting together acrylonitrile and aqueous hydrogen peroxide at pH 7-8 and 30-60 DEG C, b) removing unreacted acrylonitrile by distillation, c) passing the reaction mixture over a solid hydrogen peroxide-decomposing catalyst, d) reacting the aqueous solution of II, obtained in this way, with III at pH 7-9 and 40-90 DEG C, e) reacting the resulting solution with a basic sodium compound at pH 9-14 and 60-95 DEG C, f) removing the ammonia which is produced by distillation and g) if desired, working up the aqueous solution of I, obtained in this way, in a manner known per se to give solid I.

Abstract: Alkali metal and alkaline earth metal salts of acyloxybenzenesulfonic acids of the formula I 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 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.

Abstract: Alkylglucosides are prepared by acetalization of glucose with an equivalent amount or an excess of a C3-C5-alkanol in the presence or an acidic catalyst by a method wherein the acetalization is carried out in the presence of an alkali metal salt of a boric acid used in an amount which is equivalent to or in excess of the amount of the catalyst. The alkylglucosides obtained can be used directly, for example as solubilizers, in particular in the cosmetic sector, or can be reacted further to give higher alkylglucosides a

Abstract: 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 SO3 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.
