摘要： In order to safely prepare peracetic acid in an organic solvent, the bottom is maintained in a certain stationary state during the preparation of aqueous peracetic acid, whereupon the vapor current of peracetic acid, acetic acid and water is absorbed with an organic phosphate with 3-30 carbon atoms. The solution obtained in this manner can be transferred by means of desorption with a low-boiling compound, e.g. an alkyl ester, into this lower-boiling solvent.

摘要： A process for desensitization of water insoluble peroxycarboxylic acids with essentially sodium sulfate in the aqueous phase, wherein the desensitized peroxycarboxylic acids is separated from the mother liquor, and the sodium sulfate contained in the mother liquor is isolated by one- or multi-stage crystallization in purified form as the deca (hepta) hydrate and this, directly or after conversion to an aqueous sodium sulfate solution, and/or anhydrous sodium sulfate is returned to the desensitization process. The process is nonpolluting and can be operated safely on the industrial scale. The peroxycarboxylic acids desensitized according to the invention are characterized by lower heavy metal content and high storage stability.

摘要： Process for continuous production of substantially anhydrous solutions of percarboxylic acid in solvent. Aqueous hydrogen peroxide is first reacted with the corresponding carboxylic acid in the presence of acid catalyst to form percarboxylic acid and water (1). The percarboxylic acid is extracted with solvent (5), to provide a solvent phase containing the percarboxylic acid (11) and an aqueous raffinate (7). The solvent phase is subjected to distillation (12) to provide the anhydrous solution (13). In this distillation (12) the hydrogen peroxide remaining in the solvent phase produced in the extraction (5), is distilled off together with water and some solvent, and the hydrogen peroxide is recovered as an aqueous phase and recycled (14). The aqueous raffinate, which contains hydrogen peroxide, is distilled to remove water (8) and the resulting concentrate is recycled (2) for use in the reaction (1).

摘要： The invention relates too method for the production of epichlorohydrin, wherein a chloropropane-containing ally chloride in excess is reacted in a first reaction stage with hydrogen peroxide. The non-reacted ally chloride is separated and returned to the reaction, wherein part of the separated ally chloride is added to a second reaction stage and reacted with hydrogen peroxide, wherein the hydrogen peroxide quantity is selected in the second reaction stage such that the ally chloride is largely reacted. The chloropropanes are separated from the reaction mixture of the second reaction stage by means of distillation and removed from the process.
