Abstract
Motor-fuel grade tertiary butyl alcohol which is prepared, for example, by reacting propylene with tertiary butyl hydroperoxide to form propylene oxide and a tertiary butyl alcohol reaction product contaminated with residual amounts of tertiary butyl hydroperoxide and ditertiary butyl peroxide can be effectively catalytically treated under mild conversion conditions including a temperature of about 80.degree. to 280.degree. C. with a catalyst composed of iron, copper, chromia and cobalt, or the oxides thereof in order to substantially selectively convert the two peroxide contaminants to tertiary butyl alcohol and to thereby provide a treated tertiary butyl alcohol product substantially free from contaminating quantities of such peroxides.
