Abstract
Ethylene glycol is prepared in an oxidation zone by the reaction of ethylene, molecular oxygen, and water in the presence of an iodine source to produce a liquid reaction product which is separated into a lower-boiling portion, a glycol fraction and a higher-boiling portion and the higher-boiling portion is recycled to the oxidation zone together with part of the lower-boiling portion.
