Abstract
In order to prepare a feedstock, isobutane is reacted with oxygen in an oxidation zone to provide an oxidation product comprising a solution of tertiary butyl hydroperoxide in unreacted isobutane. A catalyst may be present to catalyze the reaction of the oxygen with the isobutane if desired. The feedstock is charged to a catalytic decomposition zone wherein the tertiary butyl hydroperoxide is decomposed in the presence of an imidazole-promoted metal phthalocyanine catalyst to provide a decomposition reaction product characterized by a compartively high conversion rate and a compartively high selectively of tertiary butyl hydroperoxide to tertiary butyl alcohol.
