Succinic acid;Butane diacid;Butanedioic acid;1,2-ethanedicarboxylic acid;amber acid
CAS : 110-15-6
formula : C4H6O4
MW : 118.09
Chinese name : succinate; Succinate
English title : Succinic acid; Butane diacid; Butanedioic acid; 1,2-ethanedicarboxylic acid; amber acid

nature Description : Prism-like white crystal. The findings of combustible. Two Crystal (α-and β - type), the α-137 ° C stability, and the β - over 137 ° C stability. Melting point in the following heating, succinic acid distillation of dehydration Anhydride. The temperature of 188 ° C, the boiling point of 235 ° C (dehydration decomposition). The relative density of 1.572 (25 / 4 ° C), the refractive index of 1.452 (20 ° C). Dissolved in water, ethanol and ether, is not soluble in chloroform, dichloro-free, almost insoluble in benzene, carbon disulfide, carbon tetrachloride and petroleum ether. Odorless.

production methods : succinate addition to exist in amber, still widespread in a variety of plants, animal tissues. More industrial method, mainly in the following categories :

1. Oxidation paraffin generated by the oxidation of various acid mixtures can be separated in butanediol.

2. Hydrogenation maleic anhydride or fumarate in hydrogenation catalysts under reaction, generate succinate and then isolated products. Nickel catalyst for precious metals or, the reaction temperature is about 130-140 ° C.

3. Acrylic oxo synthesis in acrylic and carbon monoxide catalyst, generating succinate. Yet industrialization.

4. Electrolytic Oxidation with sulfuric acid anhydride and water by 1:0.5:4 ratio in ceramic electrolyzer electrolysis, available succinate.

5. Acetylene law acetylene and carbon monoxide and water in [CO (CO) 4] the presence of catalysts. 80-250 ° C reaction temperature, pressure 2.94 - 49.03MPa in acidic media reaction available succinate.

purposes : basic organic chemicals. Mainly used in the coatings, dyes, adhesives and medicine. Succinic acid production by the alkyd resin is the best of flexure, flexibility and water resistance. Succinate the two phenyl ester is a dye intermediates, and anthraquinone reaction generated anthraquinone dye. The pharmaceutical industry made available its production sulfa drug, vitamin A, vitamin B and felt so. In addition, succinic acid in paper manufacturing, the textile industry has a wide range of uses, but also can be used as a lubricant, photographic chemicals and surfactants raw materials. Succinic acid can be made for food ilizers liquor, fodder, sweets and other flavorings.
