Abstract
Motor-fuel tertiary butyl alcohol contaminated with residual amounts of tertiary butyl hydroperoxide, ditertiary butyl peroxide and allyl tertiary 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 160.degree. to 200.degree. C. with a catalyst consisting essentially of vitrified silica to substantially completely decompose the peroxide contaminants to thereby provide a treated tertiary butyl alcohol product substantially free from contaminating quantities of such peroxides.
