Catalytic Activity and Acidic Property of Silicon Pyrophosphate*

概要

論文の詳細を見る
Catalytic activity test was carried out by a pulse reactor over a silicon pyrophosphate catalyst, which was prepared by the reaction of triethyl phosphate and silicon tetrachloride. Acidic property, X-ray pattern and infrared spectrum of catalyst sample were measured to characterize the catalyst structure. In the cracking of cumene 80.8％ of conversion to benzene was obtained over the silicon pyrophosphate catalyst, while a commercial solid phosphoric acid catalyst gave a 57.5％ conversion under the same reaction conditions.
