Procedure

A mixture of 10.02 g of 200 proof ethanol and 0.502 g of 98% sodium succinate was prepared and heated to 30° C. These quantities allowed for a final solution of 10 wt % succinic acid in ethanol to be obtained upon acidification. The solubility of succinic acid in ethanol at 30° C. is about 12 wt %. Sulfuric acid (H2SO4) (0.338 g, 98%) was added to the ethanol/sodium succinate slurry with stirring to produce free succinic acid and sodium sulfate.
