INFLUENCE OF PRODUCTS AND PRETREATMENTS ON THE KETONISATION OF ACETIC ACID OVER IRON OXIDE

Abstract

'With a view to understand the mechanistic details of the ketonisation of acetic acid on iron oxide the influence of products on the rate of the reaction was studied at different temperatures. Inhibition of the ketonisation due to water is greater than that due to carbon dioxide and acetone at all temperatures. The extent of catalytic dehydration and dehydrogenation of alcohols and the ketonisation of acetic acid was also studied on catalysts reduced to different degrees. The results suggest the necessity of dehydrogenation as well as dehydration activities of the catalyst for the ketonisation reaction.
