PROCESS FOR PREPARATION OF CATALYST AND PROCESS FOR PRODUCTION OF ALKYLENE OXIDE USING CATALYST PREPARED BY THE SAME.

摘要

In the case where hydrogen and oxygen are continuously provided with olefin such as propylene to produce alkylene oxide, there was a problem that an amount of alkylene oxide produced is gradually decreased with decline of an catalytic ability of a catalyst to be used. In order to solve the problem, disclosed are a process for preparation of a catalyst comprising a step of contacting a catalyst containing titanosilicate and a noble metal with alcohol having a carbon number of 1-12, and a process for production of alkylene oxide comprising reacting hydrogen, oxygen and olefin in the presence of a catalyst which is prepared by the process as described above and a nitrile compound.
