The catalyst- and solvent-free liquid phase air oxidation reaction of ethylbenzene (EB) to 1-phenyl ethyl hydroperoxide (PEHP) was investigated at scheduled temperature and pressure with a separate deacidifying zone. The oxidation reaction was done in the titanium fabricated reactor at an oxygen volume fraction in the outlet gas less than 0.3%. The effects of several reaction parameters were studied in detail. In the optimal reaction conditions and instructions given in this work, the high selectivity to PEHP (above 95%) was achieved with EB conversion around 13%, and a clean feed (water and acid-free) was provided for the propene epoxidation reaction.

低氧体积分数下乙苯的非催化液相空气氧化为1-苯基氢过氧化物

在预定的温度和压力下，通过单独的脱酸区研究了乙苯（EB）的无催化剂和无溶剂液相空气氧化反应，生成1-苯基乙基氢过氧化物（PEHP）。氧化反应在钛制反应器中在出口气体中的氧气体积分数小于0.3％的条件下进行。详细研究了几种反应参数的影响。在这项工作给出的最佳反应条件和指导下，以13％的EB转化率实现了对PEHP的高选择性（95％以上），并且为丙烯环氧化反应提供了清洁的进料（无水和无酸）。
