Methyl tert-butyl ether(MTBE)was prepared from tert-butanol and methanol by etherification reaction with domestic resin catalyst A(hereinafter referred to as catalyst A).The effects of temperature,space velocity,molar ratio of methanol to tert-butanol,and water content of the raw material on conversion rate of tert-butanol and MTBE selectivity were inves-tigated in a pilot plant,and the appropriate process conditions were determined.Compared with the existing indexes of the industrial reaction process between tert-butanol and methanol,the technical indexes of synthesizing MTBE with catalyst A were better,and catalyst A could be used instead of imported catalyst.
