An improved method is disclosed for preparing sodium and calcium 2,2ʹ-oxodisuccinates from maleic anhydride, or maleic acid, and malic acid, in which ether-bond formation is conducted with both calcium and sodium ions copresent in an ultimately homogeneous, concentrated, basic aqueous environment at temperatures between about 65°C and about 85°C.
Under these conditions, 2,2ʹ-oxodisuccinate salt production is an unexpectedly rapid, effective, convenient and potentially economical process.
