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 an unsupported catalyst composed of nickel, copper, chromia and iron, or the oxides thereof, or a catalyst containing nickel, copper, chromia and iron which is supported on silica 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.
