Kodi N-Methylpyrrolidone ndi chiyani?
N-Methylpyrrolidone (NMP) ndi organic pawiri wopangidwa ndi 5-membered lactam.Ndi madzi opanda mtundu, ngakhale zitsanzo zodetsedwa zimatha kuwoneka zachikasu.Imasakanikirana ndi madzi komanso zosungunulira zopezeka m'chilengedwe.N-Methylpyrrolidone (NMP) ndi zosungunulira zabwino kwambiri, zomwe zimagwiritsidwa ntchito kwambiri popaka, mafuta, mankhwala, mankhwala, mabatire a lithiamu ndi zina.
M'makampani opanga mankhwala, N-Methylpyrrolidone (NMP) imagwiritsidwa ntchito popanga mankhwala ndi njira zonse zoperekera pakamwa ndi transdermal, zomwe zimagwiritsidwa ntchito kwambiri pamankhwala, mankhwala ochizira Chowona Zanyama, mankhwala apakatikati.
M'munda wa mafakitale, N-Methylpyrrolidone (NMP) ingagwiritsidwe ntchito mu ndende ya acetylene, kuchotsa butadiene, zipangizo zamagetsi zamagetsi, zokutira zapamwamba, zowonjezera mankhwala, inki, pigment, mafakitale oyeretsa mafakitale ndi mafakitale ena.NMP imagwiritsidwanso ntchito kwambiri pakupanga batri ya lithiamu ion, monga chosungunulira cha electrode kukonzekera.Mabatire a lithiamu-ion amagwiritsidwa ntchito kwambiri pazinthu zamagetsi zonyamula, monga laputopu, mafoni am'manja ndi makamera a digito.
Amagwiritsidwanso ntchito ngati zosungunulira pokonzekera malonda a polyphenylene sulfide.Potengera chikhalidwe chake chosasinthika komanso kuthekera kosungunula zinthu zosiyanasiyana, N-Methylpyrrolidone (NMP) itha kugwiritsidwanso ntchito m'mafakitale a petrochemical ndi mapulasitiki ngati zosungunulira.
Mwachidule, N-Methylpyrrolidone (NMP) yakhala chinthu chofunikira kwambiri chamankhwala chomwe chimathandizanso kwambiri m'mafakitale osiyanasiyana.
Kodi N-Methylpyrrolidone imapangidwa bwanji?
Pali njira zingapo zomwe zingagwiritsidwe ntchito popanga N-Methylpyrrolidone (NMP) Njira imodzi yodziwika bwino yopangira NMP imaphatikizapo kuchiza γ-butyrolactone(GBL) ndi methylamine, yomwe imakhala yotentha kwambiri komanso kuthamanga kwambiri. mu chubu chosakanizira ndi γ-butyrolactone (GBL) akhoza kupangidwa ndi dehydrogenated wa 1,4-Butanediol (BDO).Njira ina imaphatikizapo hydrogenation ya N-methylsuccinimide komanso momwe acrylonitrile ndi methylamine yotsatiridwa ndi hydrolysis.
Njira ina yopangira N-Methylpyrrolidone (NMP) ndi njira ya pyrrolidone yomwe imachokera ku pyrrolidone ndi haloalkanes ngati zipangizo.
