Recovery of purified ditertiary butyl peroxide

摘要

It has been discovered in accordance with the present invention that a tertiary butyl alcohol/ditertiary butyl peroxide azeotrope may be recovered from a product containing tertiary butyl alcohol and ditertiary butyl perioxide by distilling the tertiary butyl alcohol product to obtain an overhead fraction containing substantially all of the ditertiary butyl peroxide as a ditertiary butyl peroxide/tertiary butyl alcohol azeotrope and other contaminants. It has been further discovered in accordance with the present invention that the ditertiary butyl peroxide can be recovered from the distillate fraction by extraction with water (e.g., in a countercurrent water extraction tower) to provide a ditertiary butyl peroxide product of any desired degree of purity.
