Versuchsvorschrift
Sulfomaleic anhydride, 3.9 gm, was dissolved in 25 ml of methanol and refluxed for 5 hours. Then, 24 gm of 25% sodium methoxide in methanol was added and the solution was refluxed for 2 hours. The methanol was then evaporated and the residue was dissolved in 100 ml of water and heated for 1 hour at 80°C. The solution was then decolorized with 5 gm of charcoal, filtered and evaporated. The crude residue of trisodium α-methoxy-β-sulfosuccinate was purified by trituration with acetic acid and then filtered, washed with acetone and dried.
