Basic catalysis of zeolites bimolecular condensation of ethanol

Abstract

It was found for the first time that ethanol mainly converted into 1-butanol by a bimolecular condensation over alkali cation zeolites. the selectivity of the condensation was higher on Rb-LiX zeolite than on all other used zeolites. the experiment results showed that the activities of condensation were related to the acid-base properties of the catalysts. the basicity of the catulyst was essential to thereaction, but on the catalyst showing higher basic strength, the activity of the reaction was not higher.

Key words: ALKALINITY, CONDENSATION REACTION, ETHANOL, ZEOLITE, BUTANOL, MOLECULAR SIEVE CATALYSTS, ACID-BASE PROPERTIES, BIMOLECULAR REACTION
