Abstract
Glycol monoethers are produced in high yields by reacting an acetal with carbon monoxide and hydrogen in the presence of a catalyst comprising a cobalt compound and a trivalent organic phosphorus compound or a bidentate chelate ligand containing nitrogen or oxygen. An aldehyde or a compound capable or releasing an aldehyde under reaction conditions and an alcohol can be used instead of the acetal.
