Synthesis Route and Production Method

Dihydropyran method: Dihydropyran is hydrolyzed by heating in nitric acid, then cooled and stirred with sodium nitrate. The product is obtained through vacuum evaporation and cooling crystallization, with a yield of approximately 70–75%.

Hydrolysis of glutaronitrile is refluxed with hydrochloric acid for 4 hours. The residue after evaporation contains glutaric acid and ammonium chloride, which are extracted with ether and purified by recrystallization.

Cyclohexanone Oxidation Method: In industry, adipic acid is produced by nitric acid oxidation of cyclohexanone, with glutaric acid as a byproduct.

By-product recovery method: Recovered from the process of producing oxidized paraffin through paraffin oxidation, with separation and purification achieved via water extraction or distillation.

Cyclopentanone Liquid-Phase Oxidation Method: An Industrial Feasible Oxidation Route.

Dihydropyran method: Preparation by oxidation of dihydropyran, suitable for specific process conditions.

1,3-Propanediol method: In the laboratory, 1,3-propanediol can be used as the raw material for preparation.

Used mainly in the fields as follows,

Production of maleic anhydride: This is one of its most core applications.

Drugs intermediates: Used for synthesizing α-ketoglutaric acid, peroxypentanoic acid, and B-(4-chlorophenyl)glutaric acid, among others, and further employed in the production of antihypertensive drugs.

Polymer Industry: Serves as an initiator for synthetic resins and synthetic rubber, and is also used in the synthesis of plasticizers.

Organic Synthesis: Can be used to prepare ester compounds such as dimethyl glutarate and diethyl glutarate.

Cleaning Agent Material: Due to its mild chemical properties and excellent compatibility, it is suitable for specific industrial cleaning applications.
