Cation exchange resin LH was prepared by halogenation and sulfonation,and then was used for etherification of alcohol and isobutene to synthesize ethyl tert-butyl ether. The influence of alcohol/isobutene molar ratios,reaction temperatures,space velocity and reaction pressure on the performance of the catalyst was investigated. The experimental results indicated that ethyl tert-butyl ether yield of 85. 5%was attained under the optimal condition as follows:the molar ratio of alcohol to isobutene 1 . 198 ,reaction temperature 65 ℃,space velocity 3 h-1 and reaction pressure 1. 50 MPa.
