Abstract: Prepn. of N-alkanoyl-polyhydroxyalkylamines of formula Z-N(R1)C(=O)R2 (I) comprises reacting polyhydroxyalkylamines of formula Z-NH-R1 (II) with alkyl esters of carboxylic acids of formula R3-O-C(=O)-R2 (III), in presence of a basic catalyst. In the prepn. of (a) the total amt. of (III) is heated to 90-130 deg.C and an aq. soln. of (II) is added, with the water introduced being continuously removed by distn. (b) the catalyst is added to the fine suspension of (II) in (III) and conversion to (I) is carried out at 70-100 deg.C with continuous removal by distn. of the alcohol, R3-OH formed and (c) conversion is in absence of organic solvents. In the formulae, Z = polyhydroxyalkyl residue of a mono- or oligo-saccharide; R1 = H or 1-8C alkyl; R2 = 1-21C alkyl; R3 = 1-4C alkyl. USE/ADVANTAGE - (I) are surfactants, used in washing and cleaning compsns. Colourless or light coloured prods. with a high (I) content and smaller amts. of starting materials and by-prods. are obtd. needing no further purification. Formation of clumps and deposits in the reactor is avoided, and the process can be used on the large scale.

Abstract: A process for the decomposition of peroxides (I), is effected by contacting a mixt. contg. (I) with oxide catalysts (II) of manganese, iron, nickel, cobalt, cerium, copper, molybdenum, vanadium and/or tungsten. Pref. (I) is hydrogen peroxide and/or an organic peroxide (II) contains manganese, iron, cerium, copper, vanadium and/or tungsten. The active mass of (II) consists of 1-100 wt.% manganese oxide and 99-0 wt.% of the oxides of iron, cerium, copper, vanadium and/or tungsten and is supported, pref. on cordierite, Al203, Ti02, silica gel and/or Zr02. The reaction is carried out at 0-80 deg.C and 0.01-50 bar. USE/ADVANTAGE - The process is useful for the controlled decomposition of peroxides. The process stream is contaminated with heavy metal ions to a lesser extent than prior art processes.

Abstract: Production of alkyl glycosides by the conversion of aqueous glycoses with a water content of 10 to 80 wt % with aliphatic primary alcohols with 5 to 30 C atoms, in which: (a) the alcohols and the glycoses are used in the molar ratio of 2:1 to 10:1; (b) 0.1 to 5 wt % of the acid form of an anionic tenside in relation to the quantity of glycoses is used as an acid catalyst with emulsifying properties; (c) 1 to 30 wt % of alkylglycosides in relation to the quantity of glycoses used are employed as a further emulsifier; (d) the aqueous glycose is preheated to 50 to 90 DEG C and to the preheated aqueous solution of glycose are correctly dosed added and mixed thoroughly to produce a reaction mixture alcohol, acid catalyst and emulsifier in such a way that an emulsion is produced; (e) the conversion takes place at a temperature of 100 to 150 DEG C and a pressure of 10 to 100 mbar, whereby the water added to the reaction mixture and that produced by conversion is continuously distilled off; (f) after the reaction has been successfully conducted, the acid catalyst is neutralised by the addition of a base so that the resultant mixture has a pH of 8 to 10; whereupon (g) the excess alcohol is distilled off at a pressure of 0.01 to 10 mbar until the residual content is less than 5 wt % in relation to the quantity of alkyl glucoside, and (h) the reaction mixture is bleached with a compound separating the active oxygen after having been converted into an aqueous past with 30 to 70 wt % alkyl glucoside with a pH of 8 to 10.

Abstract: Alkylglucosides are prepared by acetalization of glucose with an equivalent amount or an excess of a C3-C5-alkanol in the presence of 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.
