Description:
01.N-methylpyrrolidinone (NMP), molecular formula :C5H9NO, English :1-Methyl-2-pyrrolidinone, colorless to light yellow transparent liquid, slightly ammonia odor, miscible with water in any proportion, soluble in ethyl ether, acetone, esters, halogenated hydrocarbons, aromatics and other organic solvents.
02.Almost all solvents completely mixed with Chemicalbook, boiling point 204ºC, flash point 91ºC, strong hygroscopic, chemical stability, carbon steel, aluminum does not corrode, slightly corrosive to copper.
03.It has the advantages of low viscosity, good chemical stability and thermal stability, high polarity, low volatility, and infinite miscibility with water and many organic solvents.
04.This product is a micro drug, the allowable limit concentration in the air is 100PPM.
USE:
01.industrial grade: lubricating oil refining, lubricating oil antifreeze, syngas desulfurization, electronic insulation materials, agricultural herbicides, pesticide additives, PVC exhaust recovery, high-grade paint, ink, pigment production of additives and dispersants. For example, it is used to extract aromatics in lubricating oil to achieve the purpose of refining lubricating oil; Because NMP has a large solubility to resin, as a solvent for resin processing can be specifically used in the manufacture of paint, floor paint, varnish, composite coating film, integrated circuit enamelled wire insulation materials, fiber fabrics and adhesives and other products.
02, ordinary grade: extraction and recovery of basic organic raw materials, such as acetylene concentration and butadiene, isoprene, aromatics and other extraction. It can be used as a solvent to recover acetylene from natural gas or light naphtha pyrolysis gas, and the purity of recovered and concentrated acetylene is 99.7%. Chemicalbook is used as extractive agent for separating and recovering high-purity butadiene from cracked C4 hydrocarbon with recovery rate of 97% and purity of 99.7%. It is used as extractive agent for recovering high-purity isoprene from cracked C5 hydrocarbon with recovery purity of 99%. When used as an aromatics extractant, due to its high solubility to aromatics and low vapor pressure, the extraction agent loss rate is low and the recovery rate of aromatics is high during the process.
03.Integrated circuit, hard disk and other requirements for strict control of metal ions and particles of the industry of deoiling, degreasing, dewaxing, polishing, rust, paint, etc., such as photoresist removal liquid, IC semiconductor industry precision instruments, LCD liquid crystal materials, PCB printed circuit board, hard disk cleaning; And artificial kidney functional membrane liquid, seawater desalination membrane liquid and other solvents produced in the pharmaceutical industry.
