Mugadziri Mutengo Wakanaka N-METHYL PYRROLIDONE (NMP) CAS: 872-50-4

tsananguro pfupi:

N-Methyl Pyrrolidone inonzi NMP, molecular formula: C5H9NO, Chirungu: 1-Methyl-2-pyrrolidinone, chitarisiko chisina ruvara kusvika kuchiedza chero chinopenya mvura, kunhuhwirira kweammonia zvishoma, kusanganiswa nemvura mune chero chikamu, inonyungudika muether, acetone Uye zvakasiyana-siyana organic solvents, hydrocarbon inonhuhwirira. yakasanganiswa nezvose zvinonyungudutsa, 204 ℃ inovira, flash point 91 ℃, yakasimba hygroscopicity, stable chemical properties, isingaparadzire carbon steel, aluminium, copper Inoodza zvishoma. NMP ine zvakanakira zve low viscosity, yakanaka kugadzikana kwemakemikari uye kugadzikana kwekupisa, yakakwirira polarity, kuderera kuderera, uye kusingaperi miscibility nemvura uye akawanda organic solvents. NMP idiki-mushonga, uye inotenderwa muganho wekuisa mumhepo ndeye 100PPM.

Zvikumbiro zveNMP

N-methylpyrrolidone (NMP) inonzi polar aprotic solvent. Iyo ine yakaderera toxicity, yakakwirira yekubikira nzvimbo uye yakatanhamara solubility. Zvakanakira kusarudza kwakasimba uye kugadzikana kwakanaka. Inoshandiswa zvakanyanya mukunhuhwirira kwehydrocarbon kubviswa, kucheneswa kweacetylene, olefins uye diolefins, zvinonyungudutsa zve polyvinylidene fluoride, electrode axiliary zvinhu zve lithium ion mabhatiri, syngas desulfurization, mafuta ekuzora, kuzora antifreeze, olefin inobvisa mupurasitiki, yakaoma polymerization muinjiniya, yakaoma polymerization zvinhu, Integrated rekita kugadzirwa, kucheneswa zvakarurama zviridzwa mu semiconductor indasitiri, matunhu mapuranga, PVC exhaust gasi kupora, kuchenesa vamiririri, dhayi ebetsero, dispersants, etc. Inoshandiswawo sechinhu chinonyungudutsa chepolymers uye chepakati chepolymerization, zvakadai seinjiniya mapurasitiki uye aramid fibers. Inogonawo kushandiswa mumishonga yezvipembenene, mishonga uye mishonga yekuchenesa. Iko kushandiswa kukuru kwemagiredhi akasiyana eN-methylpyrrolidone akanyorwa pazasi:

1. Indasitiri giredhi: mafuta ekunatsa, mafuta ekuzora antifreeze, syngas desulfurization, zvemagetsi insulation zvinhu, zvekurimisa herbicides, pesticide anobatsira, PVC exhaust gasi kupora, anobatsira uye dispersants pakugadzirwa kwepamusoro-giredhi coatings, ingi, pigments, etc. Semuenzaniso, chinangwa che hydrocarbon chinoshandiswa kuburitsa kabhoni yemafuta ekuzora. kuchenesa mafuta ekuzora; nekuda kwekunyungudika kwakanyanya kweNMP kune resin, inogona kushandiswa sechinhu chinonyungudutsa cheresin uye Chemicalbook kuti ishandiswe mukugadzira machira, pendi yepasi, mavhanishi, mabhanhire akaumbwa, firimu-kuumba, yakabatanidzwa Circuit enameled wire insulation zvinhu, fiber machira uye adhesive uye zvimwe zvigadzirwa.

2. Ordinary giredhi: kudhirowa uye kudzoreredzwa kwezvakatanga organic raw materials, senge acetylene concentration uye kutorwa kwebutadiene, isoprene, anonhuwirira hydrocarbons, etc. Inogona kushandiswa sechinhu chinonyungudutsa chekudzoreredza acetylene kubva kugasi rechisikigo kana light naphtha thermal cracking gasi, uye kuchena kwekuwanazve yakanyungudutswa 9% kusvika semushonga wekuparadzanisa uye kudzorera yakakwirira-kuchena butadiene kubva kune yakatsemuka C4 hydrocarbons, chiyero chekudzorera chinogona kusvika 97%. %, kuchena kwekudzorerwa butadiene i 99.7%, uye inoshandiswa sechinhu chinobvisa chekudzorera high-purity isoprene mukupwanya C5 hydrocarbons, uye kuchena kwe isoprene kunosvika 99%; kana ichishandiswa sechinobvisirwa mahydrocarboni anonhuwirira, ine kunyungudika kwakanyanya kumahydrocarboni anonhuwirira. Nekuderera kwehuputi hwemhepo, chiyero chekurasikirwa kwechigadzirwa chakaderera uye chiyero chekudzorera chearomatics chakakwirira.

3. Reagent giredhi: Degreasing, degreasing, dewaxing, polishing, rust prevention, pende stripping, etc. mumaindasitiri anoda kudzora kwakasimba kwesimbi ions uye microparticles mumatunhu akabatanidzwa, hard disks, etc. Kucheneswa kwezviridzwa zvakanyatsojeka, LCD liquid crystal materials, PCB yakadhindwa mapuranga ematunhu, hard disks; uye zvinonyungudutsa zvinogadzirwa muindasitiri yemishonga zvakaita seyekuita itsvo inoshanda membrane fluid, mvura yegungwa desalination membrane fluid, nezvimwe.
