A method of producing and separating durene.

摘要

Durene is recovered from a mixture containing durene and hydrocarbons boiling in the gasoline range by fractionating to mixture to produce lower and higher boiling fractions and then cooling the higher boiling fraction to a point where crystallization occurs. The crystallized durene is separated from the mother liquor and subsequently is washed with a wash fluid. The wash fluid, which can be methanol, is returned to the process stream wherein it is converted to gasoline and durene. The separated mother liquor is added to the gasoline fraction. The original mixture of durene and gasoline is obtained by the catalytic conversion of synthesis gas or alcohols and ethers.
