Process for decomposing peroxides

摘要

The invention relates to a process for decomposing peroxides contained in organic carboxylic acids which are obtained by oxidation and then purified by distillation. This process is characterised in that there is imposed, in the first distillation column; - either a temperature at the bottom of the column which is at least equal to 175 DEG C and a space velocity which does not exceed 3 hours<-1>; - or a temperature at the bottom of the column which is greater than or equal to 200 DEG C. i
