실험 절차

Eight parts by weight of sodium hydroxide and 9.8 parts by weight of maleic anhydride are added to 100 parts by weight of water to obtain a homogeneous solution of disodium maleate. On addition of 10.4 parts by weight of sodium bisulfite to the foregoing solution and stirring, the reaction proceeds exothermically. After the evolution of heat has settled down, the stirring is continued for a further 3 hours at 60°C. A rotary evaporator is then used and the water is removed from the reaction mixture to obtain 26.4 parts by weight of a white powder of trisodium sulfosuccinate.
