Abstract
Glycol esters of an olefin are prepared by contacting an olefin and a molecular oxygen containing gas in a carboxylic acid medium in the presence of a catalyst. Selectivities to the desired glycol esters are improved by treating the viscous residue and the precursor light components separated from the oxidation effluent by contacting them with water. In a preferred embodiment both residue and precursor light components streams are fed to the same zone wherein they are converted to additional glycol.
