ABSTRACT:
Gamma-Butyrolactone is produced by passing vaporized maleic acid/anhydride or succinic acid/anhydride or mixtures thereof, water, and hydrogen, over a metallic catalyst capable of hydrogenolyzing a carboxylic group to a methyleneoxy group. Even though water is also a byproduct of the reaction, very high yields of gamma-butyrolactone are obtained, and the added water plays a key role in extending catalyst life by suppressing the formation of coke and tar.
