Abstract
Durene is recovered from a mixture rich in durene and containing hydrocarbons boiling in the gasoline range by cooling the mixture to a point where crystallization occurs and separating the crystallized durene. The durene subsequently is washed with a wash fluid. The wash fluid which can be methanol, is returned to a process wherein it is converted to gasoline and durene. The separated mother liquor is added to the gasoline fraction. The original mixture is obtained by the catalytic conversion of synthesis gas and methanol or by other means.
