ABSTRACT:
This invention relates to the manufacture of ethylene glycol and more particularly to a low pressure process for making ethylene glycol comprising reacting synthesis gas, i.e. a mixture of carbon monoxide and hydrogen, plus 1,3-dioxolane in the presence of a homogenous liquid catalyst containing an effective amount of cobalt-containing compound, a silane or germane-containing promoter dispersed in a dioxolane solvent at a temperature of at least 50.degree. C. and a pressure of at least 500 psi.
