    摘要: A continuous process for the manufacture of carboxylic peracids by reacting the corresponding carboxylic acid with hydrogen peroxide in the presence of a catalyst and in the presence of an inert organic liquid which is a solvent for the peracid and is capable of forming a heterogeneous azeotrope with water, removing the water present in the reaction mixture by distillation of the water/organic liquid azeotrope, and keeping sufficient water in the reaction mixture to allow the formation of an aqueous phase which is separate from an organic phase containing the organic liquid.

    摘要: Quaternary ammonium compounds having the general formula: ##STR1## in which, R.sub.1 is an alkyl or aryl group, unsubstituted or substituted by at least two ester groups;R.sub.2, R.sub.3 and R.sub.4 are alkyl, aryl, aryl alkyl or alkyl aryl groups substituted by ester groups comprising no more than 10 carbon atoms;m, r and n are whole numbers;A.sup. .circle.r- is an anion such that m.times.r=n. The compounds are obtained by treatment of a tert.alcohol-amine with an alkylating or arylating agent and an acylating agent. They may be used as activators of persalts in wash compositions.

    摘要: A process for the manufacture of olefine oxides, comprising reacting, with an olefine, an organic solution of percarboxylic acid which is obtained by reacting the corresponding carboxylic acid with hydrogen peroxide. The organic solvent employed is a mixture of inert organic solvents which does not form an azeotrope with the olefine to be epoxidized or with the olefine oxide, and which contains a volatile solvent, the boiling point of which is lower than that of the olefine oxide, and a solvent of low volatility, the boiling point of which is higher than that of the olefine oxide.

    摘要: Halogenated polyether-polyols lacking terminal primary chlorohydrin and hydroxyl groups are reacted with organic isocyanates to produce semi-rigid or rigid polyurethane foam having excellent physical, mechanical and processing characteristics and good fire-resistance. The polyether-polyols are used individually, as admixtures with each other and/or as admixtures with non-halogenated polyether-polyols.
