PROCESS FOR PRODUCING PROPYLENE OXIDE |
摘要 |
A process for producing propylene oxide, characterized in that it comprises the following steps and the concentration of isopropylbenzene hydroperoxide in the cumyl alcohol solution is 5 wt.% or lower at the time when the epoxidization step is completed. Oxidation step: a step in which isopropylbenzene is oxidized to obtain isopropylbenzene hydroperoxide. Epoxidization step: a step in which the isopropylbenzene hydroperoxide obtained in the oxidation step is reacted with propylene to obtain propylene oxide and cumyl alcohol. Hydrogenolysis step: a step in which the cumyl alcohol obtained in the epoxidization step is subjected to hydrogenolysis to obtain isopropylbenzene, and the isopropylbenzene is recycled as a feed material to the oxidation step. |
