八、Application
N-methyl pyrrolidone (NMP) is a non-proton transfer in polar solvents. With little toxicity, high boiling point, dissolved strength stands out. Benefits of selecting strong and good stability. Widely for aromatic extraction, and acetylene, and olefin, and II olefin of purification, poly partial II fluoride vinyl of solvent, lithium ion battery of electrode secondary material, synthesis gas desulfurization, and lubricant refined, and lubricant anti-frozen agent, and olefin extraction agent, and, and difficult dissolved engineering plastics aggregate Shi of solvent, agricultural herbicide, insulated material, and IC making, semiconductor industry precision instruments, and circuit board of wash NET, PVC exhaust recovery, cleaning agent, and dye auxiliaries, and dispersed agent,. Solvent for polymers and polymerization reaction of the media, such as engineering plastics and Kevlar. Also available in terms of pesticides, pharmaceuticals and cleaning agents。
NMP is efficient selective solvent, easy recovery and so on. NMP in the electronic industry uses mainly in the following areas:
(1) NMP is used as solvent of poly vinylidene fluoride and lithium-ion secondary battery electrode material.
(2) can be used for photoresist removal liquid, LCD liquid crystal materials production;
(3) used in the production of the solvents;
(4) the cleaning of semiconductor industry of precision instruments, printed circuit boards.
