Succinic Acid

Succinic acid is a colorless crystal; Relative density 1.572 (25/4 ℃), melting point 188 ℃, decomposes at 235 ℃; Distillation under reduced pressure can sublime; Soluble in water, slightly soluble in ethanol, ether, and acetone.In industry, succinic acid is often prepared by catalytic reduction of succinic acid, and succinic acid can also be prepared by hydrolysis of succinonitrile. In the laboratory, succinic acid can be obtained by reacting two molecules of sodium salt of diethyl malonate with iodine, followed by hydrolysis and decarboxylation.Melting point: 188 ℃ Boiling point: 235 ℃ (partially converted to anhydride).
