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: Textiles are pre-treated in an aq. medium by alkaline boiling and/or bleaching, in presence of cpds. of formula (I), where R = 6-10C alkyl; X = H, Na, K or NR1R2R3R4; R1, R2, R3, R4 = H, 1-4C 1-4C alkyl or -CH2CH2OH. R = 7-9C alkyl, pref. 2,4,4-trimethylpentyl or 1-ethylpentyl. The amt. of (I) is 0.1-2 wt.%, w.r.t. the aq. medium.

Abstract: THE PRESENT INVENTION RELATES TO A PROCESS FOR PREPARING 3-CYANO-3,5,5-TRIMETHYLCYCLOHEXANONE (ISOPHORONENITRILE) BY REACTING ISOPHORONE WITH HYDROGEN CYANIDE IN THE PRESENCE OF A BASE AS A CATALYST TO OBTAIN A CRUDE ISOPHORONENITRILE PRODUCT, AND SUBSEQUENTLY DISTILLING THE CRUDE ISOPHORONENITRILE PRODUCT, WITH THE ADDITION BEFORE DISTILLATION OF AT LEAST ONE SPECIFIC SULFONIC ACID OR SPECIFIC CARBOXYLIC ACID. IN ADDITION, THE PRESENT INVENTION RELATES TO THE USE OF A SPECIFIC SULFONIC ACID OR OF A SPECIFIC CARBOXYLIC ACID AS A NEUTRALIZING AGENT BEFORE DISTILLATION OF A CRUDE ISOPHORONENITRILE PRODUCT WHICH HAS BEEN OBTAINED BY REACTING ISOPHORONE WITH HYDROGEN CYANIDE IN THE PRESENCE OF A BASE AS A CATALYST, IN ORDER TO AVOID PRECIPITATES IN THE NEUTRALIZATION OF THE BASE USED AS A CATALYST WITH AN ACID.
