Abstract
Tertiary butyl alcohol is prepared by the catalytic decomposition of tertiary butyl hydroperoxide, preferably in solution in tertiary butyl alcohol, in the presence of a metal porphine catalyst, optionally promoted with a C.sub.1 to C.sub.18 alkyl thiol and an amine, such as an iron (III) or manganese (III) porphine and, optionally, a thiol such as dodecane thiol and an amine, such as a heterocyclic amine (e.g., pyridine, quinoline, isoquinoline, imidazole or a 1-alkyl or 2-alkyl imidazole).
