Abstract: The process entails the extraction of long-chain alkyl glucosides from reaction mixtures which can be obtained by reacting monosaccharides and alcohols containing at least 8 C atoms or by transacetalisation of short-chain alkyl glucosides with alcohols having at least 8 C atoms, and which in each case are adjusted to a pH above 6, with the aid of water.

Abstract: Etherified polyoxyalkylene derivatives of the formula where R1 is hydrogen, C1-C20-alkyl or C3-C5-alkenyl, R2 and R3 independently of one another are each hydrogen, methyl or ethyl, R4 is C1-C4-alkyl and m and n are identical or different and are each greater than or equal to 0, with the proviso that the sum of m and n is from 3 to 300, are prepared by reacting the corresponding hydroxyl-containing polyoxyalkylene derivative with a dialkyl sulfate in the presence of an alkali metal hydroxide by a process in which the reaction is carried out at from 20 DEG to 60 DEG C. in the presence of an aqueous solution of an alkali metal hydroxide, the concentration of alkali metal hydroxide during the entire duration of the reaction being not less than 35% by weight, based on the aqueous phase, and not less than 1 mole of dialkyl sulfate and not less than one mole of alkali metal hydroxide are used per mole equivalent of organic hydroxyl groups.

Abstract: Preparation of aqueous solutions of alkali metal salts or of the ammonium salt of propyne-3-sulphonic acid by reaction of propargyl chloride with an aqueous solution of an alkali metal or ammonium sulphite, hydrogen sulphite and/or disulphite by carrying out the reaction in the presence of 1 to 100% by weight, relative to the amount of the aqueous phase, of one or more organic liquids which are water-immiscible or virtually water-immiscible, insensitive to hydrolysis and inert to propargyl chloride and the alkali metal or ammonium salts of sulphurous acid or their condensation products, or adding the organic liquid after the reaction and subsequently separating off the organic phase from the aqueous phase.
