    摘要： The preparation of alkyl glycosides by reaction of aqueous glycoses having a water content of 10-80% by weight with aliphatic primary alcohols having from 5 to 30 C atoms is described, in which(a) the alcohols and the glycoses are employed in a molar ratio of 2:1 to 10:1,(b) 0.1-5% by weight, based on the amount of the glycoses employed, of the acidic form of an anionic surfactant is used as the acidic catalyst having emulsifying properties,(c) 1-30% by weight, based on the amount of the glycoses employed, of alkyl glycosides is used as a further emulsifier,(d) the aqueous glycose is preheated to 50.degree.-90.degree. C. and the preheated aqueous solution of the glycose is metered with effective mixing into the reaction mixture of alcohol, acidic catalyst and emulsifier in such a manner that an emulsion is formed,(e) the reaction is carried out at from 100.degree. to 150.degree. C. and from 10 to 100 mbar, the water introduced into the reaction mixture and the water formed by the reaction being continuously removed by distillation,(f) after the reaction has ended, the acidic catalyst is neutralized by addition of a base such that the resulting mixture has a pH of 8-10, then(g) the excess alcohol is removed by distillation at from 0.01 to 10 mbar down to a residual content of less than 5% by weight, based on the amount of alkyl glycoside present, and(h) the reaction mixture is bleached at pH 8-10 after conversion into an aqueous paste having a content of from 30 to 70% by weight of alkyl glycoside using a compound eliminating active oxygen.

    摘要： In a process and an apparatus for the continuous preparation of N-acylamino carboxylic acids and N-acylamino sulfonic acids, and their alkali metal salts, from the alkali metal salts of amino carboxylic acids and amino sulfonic acids, respectively, and carbonyl halides in a reactor designed as circulating circuit, the reactants are fed for immediate reaction into the circulating circuit, and a part of the product solution corresponding to the amount fed in is continuously discharged from the circulating circuit. The reactants are circulated by a circulating pump. The temperature in the reactors is controlled. The heat produced in the reaction is removed.
