    • 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° to 200°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.
    • 被残留量的叔丁基氢过氧化物和二叔丁基过氧化物(其通过例如通过丙烯与叔丁基过氧化氢反应形成环氧丙烷和马达燃料级叔丁醇反应产物制备)的汽油燃料级叔丁醇可以 在温和转化条件下,包括基本上由镍,铜,铬和钡组成的催化剂基本上选择性地将两种过氧化物污染物转化为叔丁醇,从而在温和转化条件下进行有效的催化处理,包括约80至200℃的温度, 基本上没有污染量的这种过氧化物的叔丁醇产物。
