Abstract: 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.

Key words: MCM-36 zeolite, ultrasonic wave, pillaring agent, intercalation
