Methyl tertiary butyl ether, diisopropyl ether and isopropyl tertiary butyl ether production in one step from crude by-product acetone

摘要

A one-step method is disclosed for synthesis of ethers from mixtures of acetone, methanol and t-butyl alcohol which comprises reacting an acetone-rich feed over a bifunctional catalyst comprising 5-45% by weight of a catalyst consisting essentially of a hydrogenation catalyst selected from one or more metals selected from Groups VIA, IB, IVB or VIII of the Periodic Table and a heteropoly acid on 55%-95% of the total weight of the catalyst of a support comprising a compound selected from the group consisting of: a. a metal phosphate or a phosphate of a metalloid element; b. 5 to 95 wt% metal phosphate or phosphate of a metalloid element supported on 95 to 5 wt% Group III or Group IV oxide; and c. a large pore silicoaluminophosphate.
