ABSTRACT:
Primary and secondary hydroperoxide contaminants in a tertiary hydroperoxide composition obtained by oxidation of a branched hydrocarbon are removed by contacting the tertiary hydroperoxide with a carboxylic acid derivative such as an anhydride and a basic compound such as sodium hydroxide. A tertiary hydroperoxide such as tertiary butyl hydroperoxide is purified with minimal loss of the desired tertiary hydroperoxide.
