Synthetic route
Mainly synthesized through the following methods
Esterification reaction method (most commonly used):
Succinic acid+excess methanol, heated and refluxed under the catalysis of concentrated sulfuric acid, produces dimethyl succinate and water.
Reaction equation:
HOOC?CH2?CH2?COOH+2CH3OH?>CH3OOC?CH2?CH2?COOCH3+2H2O
Catalytic carboxylation method: Butadiene reacts with carbon dioxide under the action of a catalyst.
Biological synthesis method: utilizing microbial fermentation, with environmental advantages (emerging method)
