How acid from a chemical reaction mixture was separated by ionic liquids

摘要

A process for removing acids from reaction mixtures using an auxiliary base, in which the auxiliary base: combines with the acid to form a salt which is liquid at temperatures at which the product of value does not significantly decompose during the removal of the liquid salt, and the salt of the auxiliary base with the product of value or the solution of the product of value in a suitable solvent forms two immiscible liquid phases.
