Succinic acid is an organic compound, a dicarboxylic acid with chemical formula (CH2)2(COOH)2. The name derives from Latin succinum, meaning amber, from which the acid may be obtained.
Succinic acid will react with sodium carbonate in aqueous solution to give sodium succinate.
Succinic acid can be bought from various wine-making suppliers.
Lastly it can be bought from chemical suppliers and online.
Succinic acid was historically obtained from the distillation of amber.
Succinic acid can be obtained from the fermentation of wines, along with acetic acid.
A more convenient route involves the partial hydrogenation of maleic acid.
Oxidation of 1,4-butanediol will yield succinic acid.
Carbonylation of ethylene glycol will also yield succinic acid.
- Make polyesters
- Make fumaric acid
- Make succinic anhydride
- Synthesis of 1,4-butanediol
Succinic acid may be irritant and should be handled with care.
Succinic acid should be kept in closed bottles, away from volatile compounds.
No special disposal is required.
