Abstract
The present invention provides a process for the production of dialkyl peroxides by reaction of an alcohol and/or an olefin with an organic hydroperoxide, using an inorganic heteropoly and/or isopoly acid catalyst.
Claims9
A process for the preparation of a dialkyl peroxide having the formula ROOR.sub.1 which comprises reacting a reagent selected from the group consisting of an alcohol having the formula ROH, an olefin having the formula:
- ##STR2## the mixtures in the liquid phase with a hydroperoxide having the formula R.sub.1 OOH, at a temperature of 20.degree.-150.degree. C. and at a pressure sufficient to maintain the liquid phase int eh presence of an effective amount of an inorganic heteropoly or isopoly acid catalyst, in the above formulae R and R.sub.1 are alkyl groups having 1 to 10 carbon atoms, and R.sub.2 and R.sub.3 are hydrogen or R.
A process for the preparation of ditertiary butyl peroxide which comprises reacting a reagent selected from the group consisting of tertiary butyl alcohol, isobutylene, and mixtures with tertiary butyl hydroperoxide in the liquid phase at a temperature of 20.degree.-150.degree. C. and at a pressure sufficient to maintain the liquid phase in the presence of an effective amount of an inorganic heteropoly or isopoly acid catalyst.
A process for the preparation of ditertiary amyl peroxide which comprises reacting a reagent selected from the group consisting of tertiary amyl alcohol, isoamylene and mixtures with tertiary amyl hydroperoxide in the liquid phase at a temperature of 20.degree.-150.degree. C. and at a pressure sufficient to maintain the liquid phase in the presence of an effective amount of an inorganic heteropoly or isopoly acid catalyst.
