PROCEDE DE SYNTHESE D'ESTERS ETHYLIQUES D'ACIDES CARBOXYLIQUES

摘要

A process is provided for the synthesis of carboxylic acid ethyl eaters by reacting a mixture of carbon monoxide and hydrogen (syngas) with a carboxylic acid or anhydride. The reaction is conducted at a temperature between 100 and 350 DEG C. and a pressure of at least 500 psi (3.45 mPa), in the presence of a ruthenium catalyst. The ethyl ester is preferably pyrolyzed to form ethylene.
