Taw qhia
N-vinylcaprolactam yog ib qho organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab kev nyab xeeb cov ntaub ntawv ntawm N-vinylcaprolactam:
Zoo:
N-vinylcaprolactam yog cov xim tsis muaj xim rau lub teeb daj nrog cov ntxhiab tsw tshwj xeeb.
Siv:
N-vinylcaprolactam muaj ntau yam kev siv hauv kev lag luam tshuaj. Nws yog ib qho tseem ceeb ntawm cov khoom siv hluavtaws, uas tuaj yeem siv los ua monomer ntawm polymers, catalyst rau cov tshuaj tiv thaiv polymerization, raw khoom rau surfactants thiab plasticizers. Nws kuj tseem siv tau rau hauv thaj chaw xws li txheej, inks, dyes, thiab roj hmab.
Txoj kev:
Ib txoj kev npaj rau N-vinylcaprolactam yog tau los ntawm cov tshuaj tiv thaiv ntawm caprolactam thiab vinyl chloride nyob rau hauv alkaline tej yam kev mob. Cov kauj ruam tshwj xeeb yog kom yaj caprolactam hauv cov kuab tshuaj uas tsim nyog, ntxiv vinyl chloride thiab alkaline catalyst, thiab cua sov cov tshuaj tiv thaiv reflux rau lub sijhawm, thiab cov khoom tuaj yeem tau txais los ntawm distillation lossis extraction.
Cov ntaub ntawv kev nyab xeeb:
N-vinylcaprolactam tej zaum yuav ua rau khaus ntawm daim tawv nqaij thiab ob lub qhov muag nyob rau hauv tej yam kev mob, thiab yuav tsum tau muab yaug nrog dej txaus tam sim ntawd tom qab sib cuag. Thaum siv thiab tuav cov khoom sib xyaw, nws yuav tsum hnav cov khoom tiv thaiv tsim nyog xws li hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv kom ntseeg tau tias qhov chaw ua haujlwm zoo. Nws yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav, kom deb ntawm hluav taws thiab cov khoom tawg. Thaum siv thiab khaws cia, thov ua raws li cov txheej txheem kev nyab xeeb thiab cov lus qhia tsim nyog.
