What downstream products of γ-butyrolactone (GBL) do you know?

In the downstream applications of BDO industry chain products, γ-butyrolactone (GBL) is an important organic chemical raw material and fine chemical intermediate, which is widely used in petrochemicals, medicines, dyes, pesticides and fine chemicals. Commonly used in the manufacture of α-pyrrolidone, NMP, polyvinylpyrrolidone, α-acetyl-γ-butyrolactone, etc.

(1) N-methylpyrrolidone (NMP)

It is derived from the condensation of γ-butyrolactone and methylamine. As an efficient and selective solvent, this product is mainly used to extract acetylene, butadiene, isoprene, and aromatic hydrocarbons in lubricating oil fractions to improve the quality of lubricating oil. It is especially used as an environmentally friendly non-toxic solvent and lithium The demand for battery electrolyte is extremely rapid; as a resin processing solvent, it is used to make a variety of vinyl coatings; as a polymerization reaction solvent, it is used to make polyimide heat-resistant resin, polyamide, polyphenylene ether, etc.; in addition, it can Synthesis of fine chemicals such as pharmaceuticals, pigments, spices and cleaning agents.

(2) Cyclopropylamine (CPA)

It is an important fatty amine containing a three-membered ring. It is mainly used in the synthesis of medicines, pesticides, and fine chemicals. It is especially used in large quantities in medicine. It is mainly used to synthesize ciprofloxacin, anthrafloxacin, spafloxacin, and ciprofloxacin. Nicotinic acid, etc.

(3) 2-pyrrolidone (α-pyrrolidone), N-vinylpyrrolidone (NVP) and polyvinylpyrrolidone (PVP)

With the continuous development of various related industries, the demand for γ-butyrolactone (GBL) in the other fields mentioned above will continue to grow, especially in medicine, pesticides, spices, artificial plasma, and the preparation of vitamins and chlorophyll. The prospects are promising and will become GBL’s new demand growth point.
