Applications of NMP

N-methylpyrrolidone (NMP) is a polar aprotic solvent. It has low toxicity, high boiling point and outstanding solubility. The advantages of strong selectivity and good stability. Widely used in aromatic hydrocarbon extraction, purification of acetylene, olefins and diolefins, solvents for polyvinylidene fluoride, electrode auxiliary materials for lithium ion batteries, syngas desulfurization, lubricating oil refining, lubricating oil antifreeze, olefin extractant, difficult Solvents in the polymerization of engineering plastics, agricultural herbicides, insulating materials, integrated circuit production, cleaning of precision instruments in the semiconductor industry, circuit boards, PVC exhaust gas recovery, cleaning agents, dye auxiliaries, dispersants, etc. It is also used as a solvent for polymers and a medium for polymerization, such as engineering plastics and aramid fibers. It can also be used in pesticides, medicines and cleaning agents. The main uses of different grades of N-methylpyrrolidone are listed below:

1. Industrial grade: lubricating oil refining, lubricating oil antifreeze, syngas desulfurization, electronic insulation materials, agricultural herbicides, pesticide auxiliaries, PVC exhaust gas recovery, auxiliaries and dispersants for the production of high-grade coatings, inks, pigments, etc. For example, it is used to extract aromatic hydrocarbons in lubricating oil to achieve the purpose of refining lubricating oil; due to the high solubility of NMP to resin, it can be used as a solvent for resin and Chemicalbook to be used in the manufacture of coatings, floor paints, varnishes, composite coatings, film-forming, integrated Circuit enameled wire insulation materials, fiber fabrics and adhesives and other products.

2. Ordinary grade: extraction and recovery of basic organic raw materials, such as acetylene concentration and extraction of butadiene, isoprene, aromatic hydrocarbons, etc. It can be used as a solvent for recovering acetylene from natural gas or light naphtha thermal cracking gas, and the purity of recovering concentrated acetylene can reach 99.7%; as an extractant for separating and recovering high-purity butadiene from cracked C4 hydrocarbons, the recovery rate can reach 97%. %, the purity of recovered butadiene is 99.7%, and it is used as an extractant for recovering high-purity isoprene in cracking C5 hydrocarbons, and the recovery purity of isoprene reaches 99%; when it is used as an extractant for aromatic hydrocarbons, it has high solubility for aromatic hydrocarbons. With low vapor pressure, the loss rate of extractant is low and the recovery rate of aromatics is high.

3. Reagent grade: Degreasing, degreasing, dewaxing, polishing, rust prevention, paint stripping, etc. in industries that require strict control of metal ions and microparticles in integrated circuits, hard disks, etc. Cleaning of precision instruments, LCD liquid crystal materials, PCB printed circuit boards, hard disks; and solvents produced in the pharmaceutical industry such as artificial kidney function membrane fluid, seawater desalination membrane fluid, etc.
