A process for the production of a storage stable desensitized aliphatic and/or aromatic percarboxylic acid, comprises reacting at least one aliphatic and/or aromatic carboxylic acid with hydrogen peroxide in the presence of sulphuric acid, and adding to the reaction mixture at least one substance which reacts with sulphuric acid to form a sulphate salt as a desensitizing agent. The substance which reacts with sulphuric acid is preferably sodium hydroxide, magnesium hydroxide or sodium aluminate. The carboxylic acid used is preferably azelaic acid, adipic acid, suberic acid, sebacic acid, 1,12- dodecandioic acid, benzoic acid, isophthalic acid or mellitic acid. |
