Process for producing ethylene glycol mono-tert-butyl ether

摘要

An improved process for producing ethylene glycol mono-tert-butyl ether by reacting ethylene glycol with isobutylene in the presence of a catalyst of strongly acidic cation-exchange material is disclosed which enables the production of ethylene glycol mono-tert-butyl ether in a high yield while suppressing the formation of by-product ethylene glycol di-tert-butyl ether by previously adding ethylene glycol di-tert-butyl ether to the reaction system and conducting the reaction at temperatures of about 60 to 130 DEG C.
