ABSTRACT:
New bisbenzoin ethers are produced. The method of producing the bisbenzoin ethers comprises the reaction of an alkyl glycol with benzoin utilizing phosphorous oxychloride as the catalyst with hydrogen chloride as acid reacting agent. The use of phosphorous oxychloride as catalyst with hydrogen chloride improves the production of benzoin ethers in general by the reaction of benzoin with the selected alcohol.
