Verfahren zur Herstellung von Percarbonsaeureloesungen

摘要

A percarboxylic acid solution is produced from an adduct of urea and hydrogen peroxide by mixing this adduct with an extracting solvent constituted by a lower alkyl ester, a lower alkyl ketone or a lower alkyl ortho-phosphate, whereby a hydrogen peroxide solution in the extracting solvent results; the said extracting solvent is replaced with the carboxylic acid corresponding to the required percarboxylic acid, whereby reaction of the carboxylic acid with the hydrogen peroxide occurs to give the required percarboxylic acid in solution in said carboxylic acid from which solution water resulting during the reaction is removed by azeotropic distillation.
