Abstract
A process for the manufacture of quinine gentisinate comprises mixing quinine and gentisic acid or a quinine salt and a gentisic acid salt in a medium capable of dissolving these components. In an example quinine base and gentisic acid each dissolved in ethyl acetate are reacted to give the salt. The same product is obtained by a double decomposition reaction between quinine hydrochloride and sodium gentisate in an aqueous medium.
