Abstract

Zeolite L was synthesized at 180 degrees C/72 h under hydrothermal condition in the presence of diethylamine and triethylamine. Effects of alkylamines on crystallization, textural and morphological behaviors of zeolite L were investigated. Alkylamines facilitated in the crystallization of phase pure zeolite L. The triethylamine modified samples exhibited highest surface area (367 m(2) g(-1)) and microporosity compared to those prepared in the presence of diethylamine. Clam-shaped crystals with nonuniform thickness of the particles were obtained in the presence of diethylamine, while triethylamine yielded cylindrical shaped crystals with hexagonal faced crystal habit. The role of amines having different chemical behaviors toward crystal growth of zeolite L was illustrated with a tentative mechanism. (C) 2014 Elsevier B.V. All rights reserved.
