ABSTRACT:
Novel polyfunctional compounds and a process for their preparation are disclosed. These compounds and their alkali metal salts are useful metal sequestrants and/or detergent builders. Selected compounds are also intermediates useful in the syntheses of aconitic acid as well as isocitric and alloisocitric acids and their lactones. The novel polyfunctional compounds are obtained from the reaction of maleic anhydride with selected active methylene or methine containing compounds.
