Procedure

A mixture of 31.83 g of 200 proof ethanol and 4.356 g of 98% sodium succinate was prepared and heated to 30° C. Sulfuric acid (2.817 g, 98%) was then added to the ethanol/sodium succinate slurry with stiffing to produce free succinic acid and sodium sulfate. Following the procedure described in Example 1, a conversion of 68.6% of sodium succinate was obtained after 1 hour.
