ABSTRACT:
Ethylene glycol mono-t-butyl ether is produced by contacting a starting mixture of feed materials comprising ethylene glycol di-t-butyl ether and ethylene glycol with a strongly acidic cation-exchange material, thereby to react said ethylene glycol and ethylene glycol di-t-butyl ether to produce ethylene glycol mono-t-butyl ether; the reaction is carried out at about 30.degree. to 130.degree. C. under an atmospheric pressure or an increased pressure; the molar ratio of the feed ethylene glycol to the feed ethylene glycol di-t-butyl ether is about 1:0.01 to 1:20; the feed material may be a mixture comprising ethylene glycol di-t-butyl ether, ethylene glycol and at least one member selected from the group consisting of ethylene glycol mono-t-butyl ether, diisobutylene, and triisobutylene; also the reaction can be carried out by either a batch process or a continuous flowing process.
