Reaction Steps
Sulfomaleic anhydride (20 gm) is mixed with 37.2 gm (0.6 mole) of ethylene glycol and heated at 80°C for 4 hours. A solution of 16 gm (0.4 mole) of sodium hydroxide in 75 ml of water is then added and the mixture heated at 80°C for 4 hours. The mixture is then mixed with acetone to precipitate trisodium α-hydroxyethoxy-β-sulfosuccinate, which is purified by repeated extractions with hot acetone to remove all ethylene glycol and water followed by filtration and drying in an oven.
