Abstract

The intermediate solvent is separated after distillation of the liquor, either in the vapour phase using boiling point differentials or in the liquid phase from the condensate using density differences i.e. with an upper and lower drain from a condensate collection tank. The intermediate is recovered in the form of an alcohol-water mixture from which the alcohol is extracted in turn using conventional means.
