Background:

2-Pyrrolidone can be miscible with water, alcohol, ether, chloroform, benzene, ethyl acetate and carbon disulfide; it is hardly soluble in petroleum ether. Its main purpose is to make polyvinylpyrrolidone (PVP) monomer N-vinylpyrrolidone (NVP). Is also a high-grade solvent. It is used in the production of pharmaceuticals, resins, acetylene recycling, and special ink for floor wax. NVP can be prepared by the reaction of 2-pyrrolidone and acetylene, and then polymerized to obtain PVP. PVP has excellent solubility, low toxicity, film-forming properties, complexation, surface activity and chemical stability. It is widely used in medicine, food, and Japan. Used in the fields of chemicals, coatings, polymer polymerization, etc., it also has many uses in textiles, printing and dyeing, papermaking, photosensitive materials, agriculture and animal husbandry, etc.

There are three main industrial production routes for 2-pyrrolidone:

1) Rabo method: the raw material acetylene and formaldehyde are first reacted to produce 1.4-butynediol, which is hydrogenated to 14-butanediol, converted to γ-butyrolactone, and then combined with Ammonia reaction produces 2-pyrrolidone.

2) Recently, due to the successful development of a new process for the production of cis or 1.4-butanediol by butane oxidation, and the abundant sources of γ-butyrolactone, it has become the main route for the production of pyrrolidone series products. 1.4 Butanediol should be obtained, which is reduced to aminobutyronitrile by partial hydrogenation, and then hydrolyzed and cyclized to 2-pyrrolidone.

On the premise of ensuring quality, the diversification of products and the fashionable style make our Purity 99.9% N-Methyl Pyrrolidone (NMP) (872-50-4) sell well at home and abroad, and have won the trust and high praise of our customers. The company practices unremitting technical research and persistent quality management. We are willing to be a qualified supplier with sincere service and high quality, and look forward to cooperating with you.
