What are the upstream raw materials of GBL? What do the downstream products contain?

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



1. Upstream items:(1) Succinic acid: Succinic acid is one of the crucial raw materials of GBL, which is able to be produced by esterification, lactonization and other reactions.(2) Maleic anhydride: Maleic anhydride is also one of the main raw materials of GBL, and GBL is able to be obtained through hydrogenation, hydrolysis and other reactions. And(3) Hydrogen: In the manufacturing process of GBL, hydrogen needs to be applied as a reducing agent.

2. Pretty interesting, huh?. Downstream items:(1)N-methylpyrrolidone(NMP):GBL is able to be applied as one of the raw materials to react with methylamine to create N-methylpyrrolidone, which is an crucial organic solvent-based products and chemical raw material.(2) Electrolyte solution: GBL is able to be applied as a solvent-based products to prepare electrolyte solution to electrochemical devices such as lithium ion batteries.(3)γ-aminobutyric acid(GABA):GBL is able to generate γ-aminobutyric acid through ring-opening polymerization, which is an crucial neurotransmitter and biologically active chemical. First The above is only a part of the upstream and downstream related items of GBL. But In fact, as an crucial organic chemical raw material, GBL has a wide range of applications in chemical, medical, pesticide, electronics and other fields, and its upstream and downstream related items are also very rich.
