In the field of chemical production raw materials, there are many upstream and downstream related products of GBL(γ-butyrolactone). The following are some of the main upstream and downstream related products:

1. Upstream products:

(1) Succinic acid: Succinic acid is one of the important raw materials of GBL, and GBL can be produced through esterification, lactonization and other reactions.

(2) Maleic anhydride: Maleic anhydride is also one of the main raw materials of GBL, which can be obtained by hydrogenation, hydrolysis and other reactions.

(3) Hydrogen: In the production process of GBL, hydrogen needs to be used as a reducing agent.

2. Downstream products:

(1)N-methylpyrrolidone (NMP):GBL can be used as one of the raw materials to react with methylamine to produce N-methylpyrrolidone, which is an important organic solvent and chemical raw material.

(2) electrolyte solution: GBL can be used as a solvent for the preparation of electrolyte solutions for electrochemical devices such as lithium ion batteries.

(3)γ-aminobutyric acid (GABA):GBL can generate γ-aminobutyric acid through ring-opening polymerization, which is an important neurotransmitter and biologically active substance.

above is only a part of the upstream and downstream related products of GBL. In fact, as an important organic chemical raw material, GBL has a wide range of applications in the fields of chemical industry, medicine, pesticide, electronics, etc., and its upstream and downstream related products are also very rich.
