Diethyl ketone prepn from ethylene, carbon monoxide and water - in inert solvent using ruthenium halide catalyst

摘要

The novel prepn. of diethyl ketone comprises reacting ethylene, CO and H2O at 150-300 degrees C/100-350 atmos. press. in the presence of an inert solvent and a Ru halide or its hydrate as catalyst. Diethyl ketone is obtained in high yields and purity, almost free from by products and contg. only small amts. of ethane. The reaction is smooth. The catalyst is specif RuCl3 or RuCl3.3H2O.
