Preparation of t-alkyl ether

Abstract

Abstract PURPOSE: To reduce the corrosion of reactors, to decrease by-products such as diisobutylene, and to raise the reactivity, in the preparation of t-alkyl ethers by the reaction of alcohols and isoolefins, by using a heteropolyacid as a catalyst. CONSTITUTION: t-Alkyl ethers are obtained by the reaction of alcohols (e.g. methyl alcohol, ethyl alcohol, etc.) and isoolefins [e.g. 2-methyl-n-butene-1, isobutylene (2-methylpropene-1), 2-methyl-n-pentene-1, etc.] in the presence of a heteropolyacid (e.g. phosphomolybdic acid, phosphotungstic acid, phosphomolybdtungstic acid, etc.) as a catalyst. Since the activity of the catalyst is very high, the reaction can be carried out even around room temperature and products can be obtained in high yield. COPYRIGHT: (C)1980,JPO&Japio
