Abstract
This invention is concerned with improving ethylene glycol ester production from the reaction of carbon monoxide and hydrogen in a homogeneous liquid phase mixture containing a ruthenium carbonyl complex catalyst and acyl compound by maintaining the combined concentration of methyl ester, ethylene glycol ester and water in the reaction medium at less than about 30 volume percent. In a preferred embodiment, a continuous process is operated in such a manner that the methyl ester, ethylene glycol ester and water products are removed from the reactor so as to maintain their total volume concentration in the reaction medium at less than about 30 percent.
