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.

We emphasize progress and introduce new solutions into the market each year for 99.8% NMP/N-Methyl Pyrrolidone CAS: 872-50-4. We promote a working atmosphere of learning, sharing and practice, so that our employees can find solutions to problems more quickly and accurately. We insist on not wasting voluntarily, and the sustainability of the industry, and take up the social responsibility of a large enterprise.
