| titleOfInvention | Recovery of purified ditertiary butyl peroxide |
| abstract | Ditertiary butyl peroxide can be recovered from a mixture of a minor amount of ditertiary butyl peroxide with a larger amount of tertiary butyl alcohol by distilling said mixture and separating a lighter distillate ditertiary butyl peroxide/tertiary butyl alcohol azeotrope fraction which is resolved by water extraction (80) into a raffinate fraction (84) comprising ditertiary butyl peroxide and an extract fraction (86) comprising water, ditertiary butyl peroxide and tertiary butyl alcohol. The azeotrope can be obtained by reacting isobutane (14) with oxygen (12) to provide a reaction product (16) comprising unreacted isobutane, tertiary butyl hydroperoxide and tertiary butyl alcohol as principal reaction products, and ditertiary butyl peroxide as a minor reaction product, the reaction product (16) being separated by distillation into an unreacted isobutane distillate fraction (22) and the azeotrope (72, 122). |
