摘要： A method is described for the selective dealkylation of 4-tertiary-alkyl-2,5-xylenol while it is admixed with 6-tertiary-alkyl-2,4-xylenol by contacting the mixture of alkylated xylenols with a polymer-bound sulfonic acid catalyst at temperatures of 60.degree. C. or less and pressures of from about 0.5 to 5 atmospheres. The method is useful in separating 2,4-/2,5-xylenol mixtures.

摘要： Crude hydroquinone containing impurities is purified in a sublimation purification apparatus where the crude hydroquinone is introduced into a stirred and fluidized bed, a carrier gas which is inert to the hydroquinone is passed therethrough, and the temperature therein is kept at about 110.degree.-170.degree.C whereby crude hydroquinone is sublimed, and thereafter a mixed gas consisting of the sublimed vapor and the carrier gas is introduced into a condenser at a temperature at about 25.degree.-90.degree.C whereby the hydroquinone only is fractionally solidified. After the sublimation purification, hydroquinone of high purity can be collected.
