Carbonylation of ethylene by carbon monoxide on metal zeolite catalysts

Abstract

1. Among metal zeolite catalysts containing palladium, rhodium, platinum, iridium, and ruthenium, palladium catalysts were found to be most active and selective in the carbonylation of ethylene by carbon monoxide. 2. By x-ray diffraction analysis it was found that the crystalline structure of high-silicon zeolites NaM and superhigh-silicon zeolites scarcely changes under the reaction conditions. There are thus new prospects for the preparation of new effective catalysts for the synthesis of carboxylic acids by carbonylation of olefins.
