Sulfosuccinates are synthesized by a reaction of maleic anhydride or an unsaturated dibasic acid anhydride with alcohols or any compound with a hydroxyl group. The maleic monoester or diester formed is then sulfonated with sodium sulfite/bisulfite for form alkyl or dialkyl sulfosuccinates, respectively, as shown in Figure 1.
