Title  Screening of Propylene Oxide Isomerization Catalyst

Abstract This paper focuses on the preparation of the allyl alcohol by catalytic isomerization of propylene oxide。 In order to find the high activity and selectivity catalyst, we screened the catalysts about propylene oxide isomerization of allyl alcohol。 A variety of catalysts were prepared, and the activity of several kinds of catalysts were detected and compared by isomerization experiment system。 Through experiments the effects of preparation conditions, reaction conditions, catalysts on the catalytic isomerization were compared。 The results show that among the various catalysts tested (for example: TiO2, lithium phosphate, solid super acid, X-type zeolite, Nano-Ag, etc。), the lithium phosphate is most suitable for this catalyst system。 The active and catalytic performance of Au supported lithium phosphate catalyst was better than that of Cu and Ag as a catalyst for the loading of lithium phosphate。 Lithium phosphate optimum calcination temperature of the catalyst is 320 ℃。 The load rate of 2。80wt。 % of the catalytic effect of Au-Li3PO4 is the best。 The catalyst in this system, the optimum temperature used was 300 ℃。

Keywords：catalysts, isomerization propylene oxide, allyl alcohol, conversion rates
