Dehydration of Ethanol over HF-treated Al2 O3 using the GC-column as Chemical Reactor

Abstract

The effect of treating •y-alumina with hydrofluoric acid on the dehydration reaction of ethanol was investigated at 325°C. The gas chromatographic column was used as a chemical reactor. The rate of formation of ethylene and ether was found to increase by such a treatment. The data obtained were explained by assuming that HF-treated alumina has exclusively Lewis acidity
