HY Zeolite Modified by Liquid Silane Deposition and Its Catalytic Activity in Selective tert-Butylation of Naphthalene

Abstract

Abstract: HY zeolite was modified by chemical liquid deposition with i-C4H9Si (OC2H5)3 and a hydrothermal treatment. Due to the modification of microp ore structure and the narrowing of pore opening in the modified samples, t he differenc e in adsorption rate between various adsorbants with different kinetic diam e ters was more pronounced. The suppression was stronger on larger molecules.

Key words: chemical liquid deposition, HY zeolite, naphthalene, tert-butyl alcohol, 2, 6-di-tert-butylnaphthalene
