Abstract
Motor-fuel grade tertiary butyl alcohol contaminated with residual amounts of tertiary butyl hydroperoxide and ditertiary butyl peroxide (which is prepared, for example, by reacting propylene with tertiary butyl hydroperoxide to form propylene oxide and a motor fuel grade tertiary butyl alcohol reaction product) can be effectively catalytically treated under mild conversion conditions including a temperature of about 80.degree. to 200.degree. C. with a catalyst consisting essentially of nickel, copper, chromium and barium 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.
