Succinic acid, Bio-based,Fermentation 99.7% Food Grade Bio Succinic Acid /Succinic Acid Powder
Introduction
Succinic acid is colorless crystal; relative density is 1.572 (25/4℃), melting point is 188℃, decomposed at 235℃; distillation under reduced pressure can sublimate; soluble in water, slightly soluble in ethanol, ether and acetone.
In industry, succinic acid is often produced by catalytic reduction of succinic acid, and succinic acid can also be prepared by hydrolysis of succinonitrile. In the laboratory, succinic acid can be prepared by reacting two molecules of sodium salt of diethyl malonate with iodine, followed by hydrolysis and decarboxylation.
The important use of succinic acid is to prepare five-membered heterocyclic compounds. For example, succinic acid loses water rapidly upon heating to form succinic anhydride, which is a furan ring compound. Succinic anhydride is an important raw material for the manufacture of drugs, dyes and alkyd resins. Succinic anhydride and ammonia are heated together to form succinimide. The hydrogen on the imino group of succinimide can be replaced by bromine to form N-bromosuccinimide, which is a brominated reagent and a mild oxidant for organic synthesis. Succinic acid has anti-spasmodic, expectorant and diuretic effects in medicine. Diethyl succinate is an important intermediate in organic synthesis. Dibutyl succinate and dioctyl ester are plasticizers of plastics. Copolymerization of diallyl succinate with 1,3-butadiene can produce synthetic rubber.
