摘　　要：采用改性β沸石催化剂,以甲醇和异丁烯为原料气相合成甲基叔丁基醚(MTBE),发现在一定范围内适当增加沸石酸性有利于MTBE的合成,并用FTIR对改性沸石的结构和性能进行了表征。Synthesis of MTBE from methanol and iso-butylene via the modified β zeolite catalysts was studied.It's found that a proper increase in acid strength and concentration was favor to MTBE synthesis.The yield of MTBE was as much as 67.4%.
