Abstract
O-alkoxyphenols are produced from cyclohexanone or cyclohexanol by chlorination of cyclohexanone or cyclohexanol to trichlorocyclohexanone and reaction of the trichlorocyclohexanone with an aliphatic, monohydric alcohol having one to four carbon atoms and a base to form an intermediate compound or compounds which are further reacted to convert the intermediate compound or compounds to an o-alkoxyphenol.
