A NEW METHOD FOR THE PREPARATION OF ZEOLITE ZSM-5 BY USING SODIUM <i>n</i>-DODECYLBENZENE SULFONATE

Abstract

Abstract Zeolite ZSM-5 was easily synthesized by using sodium n-dodecylbenzene sulfonate (SDBS) in place of organic ammonium and/or phosphonium ions. A well-crystallized ZSM-5 was obtained by the mild hydrothermal treatment of a reaction mixture composed of SDBS and alumina-silica gel at about 180 °C and PH2O ≈10 kg/cm2 for 4 h.
