- 中文摘要: The alkylation of methanol by triethylamine to form ethyl methyl ether was studied in the temperature range 310-330.degree.C using .gamma.-alumina and silica-aluminas differing in their silica content. The effect of treating .gamma.-alumina with hydrochloric and boric acid on the reaction rate was also investigated. The results obtained for ether formation over .gamma.-alumina show that the reaction is first order for methanol and zero orde for triethylamine. Alumina-H/sub 3/BO/sub 3/ was found to be the most active catalyst whereas alumina-HCl is the least active towards ether formation. The activity of silica-alumina is proportional to its silica contents.
