Document Type and Number:
Japanese Patent JP2007534647
Kind Code:
A
Abstract:
Method of separating acids from reaction mixtures by means of an auxiliary base, where the auxiliary base b) reacts with the acid to form a salt which is liquid at temperatures at which the desired product is not significantly decomposed while the liquid salt is being separated off and c) the salt of the auxiliary base forms two immiscible liquid phases with the desired product or the solution of the desired product in a suitable solvent, in which the auxiliary base used is an alkylmidazole, which has a solubility in 30% strength by weight sodium chloride solution at 25° C. of 10% by weight or less and whose hydrochloride has a melting point below 55° C.
