摘要:
In a process for producing phenol and cyclohexanone, a cleavage feed containing greater than 40 wt% and no greater than 95 wt% cyclohexyl-1-phenyl-1-hydroperoxide, and at least 5 wt% and less than 60 wt% cyclohexylbenzene is mixed with at least phenol, cyclohexanone, water, and sulfuric acid to produce a cleavage reaction mixture containing from 15 wt% to 50 wt% phenol, from 15 wt% to 50 wt% cyclohexanone, from 1 wt% to 10 wt% cyclohexyl-1 -phenyl- 1 -hydroperoxide, from 5 wt% to 60 wt% cyclohexylbenzene, from 0.1 wt% to 4 wt% water, and from 10 wppm to 1000 wppm sulfuric acid. The cleavage reaction mixture is then reacted at a temperature from 30°C and to 70°C, and a pressure of at least 1 atmosphere for a time sufficient to convert at least 50% of said cyclohexyl-1-phenyl-1-hydroperoxide in said cleavage reaction mixture and produce a cleavage effluent containing phenol and cyclohexanone.
摘要(中):
在生产苯酚和环己酮的方法中,混合含有大于40重量%且不大于95重量%环己基-1-苯基-1-氢过氧化物和至少5重量%且小于60重量%环己基苯的裂解原料混合 至少含有苯酚,环己酮,水和硫酸,以产生裂解反应混合物,其含有15重量%至50重量%的苯酚,15重量%至50重量%的环己酮,1重量%至10重量%的环己基-1 苯基-1-过氧化氢,5重量%至60重量%的环己基苯,0.1重量%至4重量%的水,以及10wppm至1000wppm的硫酸。 然后将裂解反应混合物在30℃至70℃的温度和至少1个气压的压力下反应足以将至少50%的所述环己基-1-苯基-1-氢过氧化物在 所述裂解反应混合物并产生含有苯酚和环己酮的裂解流出物。
