The alkylation of methanol by triethylamine to form ethyl methyl ether was studied in the temperature range 310‐330° C using γ‐alumina and silica‐aluminas differing in their silica content. The effect of treating γ‐alumina with hydrochloric and boric acid on the reaction rate was also investigated. The results obtained for ether formation over γ‐alumina show that the reaction is first order for methanol and zero orde for triethylamine. Alumina‐H 3 BO 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.
