Separating 2,5-xylenol from a mixture of 2,5-xylenol and 2,4- xylenol

摘要

A mixture of 2,4-/2,5-xylenol can be alkylated with a suitable alkylating agent over a strongly acidic divinylbenzene-styrene copolymer to afford a greater amount of 4-t-alkyl-2,5-xylenol than 6-t-alkyl-2,4- xylenol provided the alkylation is carried out at a suitably low temperature of up to 60° C.
