1,4-Butanediol-catalyzed dehydrogenation of γ-butyrolactone (GBL) to γ-butyrolactone (BDO) is an important application of BDO. GBL is an important organic chemical raw material and fine chemical intermediate nmp solvent. It is mainly used in organic synthesis to produce cyclopropylamine, α-pyridone, n-methylpyridone, α-acetyl-γ-butyrolactone, n-vinylpyrrolidone and polyvinylpyrrolidone, and can also be used as a paint remover, so It is widely used in petrochemical, pharmaceutical, pesticide and other fields. Used in electronic applications, mainly for export

GBL Industry Chain Situation

NMP is a different polarity solvent in the process of aprotic signal transmission. It has the advantages of low toxicity, high boiling point, outstanding ability to solve problems, strong selectivity and good stability nmp. It can be widely used in the production of aromatics for extraction; acetylene , the purification of olefins and diolefins, and is also used to study the solvents of polymers and the medium of polymerization system reactions, such as polyamide, polyimide, polyphenylene sulfide and other engineering plastics and aramid fibers. The use of insulating structural materials, pesticides, pigments and cleaning agents, etc.

Main application fields of NMP

NMP products are widely used in lithium batteries, pharmaceuticals, pigments, cleaning agents, insulating materials and other industries 1 methyl 2 pyrrolidone. At present, the main production market is concentrated in the manufacture of lithium-ion batteries, electric vehicle power batteries, para-aramid fibers and other fields.

Aramid fiber: It is a new type of national high-tech synthetic fiber, which can be mainly divided into two types: para-aramid fiber (PPTA, aramid 1414) and meta-aramid fiber (PMIA, aramid fiber) 1313).

Features: It has excellent properties such as ultra-high strength, high mold, high temperature resistance, acid and alkali resistance, and light weight. Its strength is 5 to 6 times that of steel wire, 2 to 3 times that of steel wire or glass fiber mold, and its toughness is 2 times that of steel wire. , but the quality is only about 1/5 of steel wire.

Wide range of uses: para-aramid fibers can be used in aerospace, marine and automotive industries; they can be used to make hard bulletproof armor and soft bulletproof vests; they can be used for repair and reinforcement of infrastructure and buildings, such as conveyor belts, cables, special Protective clothing, sports equipment, electronic equipment, etc.

As a synthetic water-soluble polymer, polyvinylpyrrolidone (PVP) has the general properties of water-soluble polymers, such as colloidal protection, film formation, adhesion, moisture absorption, solubilization or solidification, etc., but its biggest feature is that it has Excellent solubility and physiological compatibility.

Among synthetic polymers, PVP soluble in water and most organic solvents is relatively rare, with low toxicity and good physiological compatibility, especially in fields closely related to people's health, such as medicine, food, and cosmetics. With the price drop of its raw material butyrolactone, it will show a good development prospect.
