Effect of Aging with Ultrasound on the Synthesis of MCM-49 Zeolite

Abstract

Abstract: The effect of aging with ultrasonic treatment on the synthesis of zeolite MCM-49 was investigated under the conditions of static hydrothermal crystallization using hexamethyleneimine (HMI) as the template. As a result of using ultrasound, highly crystalline MCM-49 is obtained from a silica source with a low specific surface area. Aging with ultrasound can noticeably broaden the crystallization range of MCM-49 and shorten the crystallization time as well as decrease the HMI/SiO2 ratio.

Key words: MCM-49 zeolite, synthesis, aging, ultrasound
