摘　　要：以四甲基铵硅酸盐为柱化剂,考察了超声作用对MCM-36分子筛合成的影响.结果表明,超声处理显著缩短了柱化剂进入已撑开的MCM-22(P)层间的插层过程的时间.通过控制插层过程的超声时间可以合成出具有不同层间距的MCM-36分子筛,而且合成的MCM-36分子筛内各层的层间距较均一.Using tetramethylammonium silicate as the pillaring agent, the effects of ultrasonic treatment on the synthesis of the MCM-36 zeolite were investigated. The results show that with the assistance of ultrasonic wave, the intercalation process, in which the pillaring agent enters into the swollen MCM-22 precursor, can be accelerated markedly. The MCM-36 zeolite with various interlayer distances can be synthesized by controlling the ultrasonic time in the intercalation process, and the interlayer distance in the MCM-36 zeolite synthesized is identical.
