Abstract
A process for the distillative separation of tertiary alkyl hydroperoxides of the formula R--OOH wherein R is a tertiary alkyl group with 4 to 6 carbon atoms from the corresponding di-tertiary alkyl peroxides resulting during their preparation, which process comprises neutralizing the reaction mixture resulting during the preparation of the tertiary alkyl hydroperoxide, subjecting same to vacuum distillation in the presence of water at a temperature of less than about 45.degree. C. and recovering the purified tertiary alkyl hydroperoxide as a bottoms product.

Process for the production of tertiary alkyl hydroperoxides of the formula
- R--OOH
- wherein
- R is a tertiary alkyl group with 4 to 6 carbon atoms, which process comprises reacting the corresponding tertiary alkyl alcohol with the hydrogen peroxide to obtain the desired tertiary alkyl hydroperoxide including dialkylperoxide impurities, neutralizing the reaction mixture, subjecting same to vacuum distillation in the presence of water at a temperature of less than about 45.degree. C., and recovering, as a bottoms product, the purified tertiary alkyl hydroperoxide in a yield of at least about 83.5%.
