Procedure

Fifty-seven grams (0.57 moles) maleic anhydride is dissolved in 500 mis ethanol. With the aid of a pH meter the pH is adjusted to 8.5-8.6 with sodium carbonate. The solution is evaporated on the roto evaporator and dried in a vacuum oven. Ninety-four grams (0.57 moles) of product having a purity of 99.4% (NMR analysis) is obtained.
