摘 要
在100℃、0.5MPa下,以Na2CO3溶液为稳定剂的异丙苯液相空气氧化反应过程中,当反应时间相同时,在环流反应器内的过氧化氢异丙苯(CHP)浓度和异丙苯氧化速率均高于鼓泡反应器。在常压、85℃的UOP工艺条件下,经过诱导期后,高/径比相对较小的鼓泡槽反应器不用稳定剂比环流反应器和鼓泡塔反应器对异丙苯的氧化反应更为有利。

[Abstract] When the temperature is 100℃ and the reaction pressure is 0.5MPa,the concentration of CHP and the Liquid oxidation with air speed of isopropylbenzene in Na2CO3 aqueous solution stabilizer are higher in the loop reactor than those in bubble reactor.Under air pressure and 85℃ used in UOP process,the oxidation speed of isopropylbenzene after the induced period with no stabilizer in bubble tank reactor having the smaller ratio of height to diameter is faster than that in loop and bubble reactors respectively.
