Abstract
A process for separating a fatty and/or rosin acid from an unsaponifiable compound. A feedstream comprising the acids and unsaponifiable compound is contacted with an aqueous alcohol solvent which is selective for and absorbs the fatty and/or rosin acid. An extract stream comprising the solvent and acids, and a raffinate stream comprising the unsaponifiable compound may then be recovered. The feedstock is best used in a diluent which is preferably a hydrocarbon.
