Cia thiab ceev faj
Khaws N-(2-Hydroxyethyl)-2-pyrrolidon CAS 3445-11-2 ntawm 5-30℃hauv kaw HDPE / amber iav nruas nyob rau hauv qhov chaw txias, qhuav, zoo-ventilated cheeb tsam, deb ntawm qhib hluav taws, muaj zog oxidants thiab ncaj qha tshav ntuj. Hnav hnab looj tes nitrile, looj tsom iav dub thiab daim npog qhov ncauj; zam kev nqus pa, daim tawv nqaij / qhov muag tiv thaiv kom tsis txhob mob me. Reseal nruj nreem tom qab siv kom tsis txhob volatilization thiab noo noo nqus. Pov tseg los ntawm cov ntawv tso cai pov tseg pov tseg; thauj raws li cov kua uas tsis muaj teeb meem, tsis muaj inhibitor xav tau, kom deb ntawm qhov kub-kub qhov chaw.
Dab tsi yog qhov txiaj ntsig ntawm kev noj N-(2-Hydroxyethyl)-2-pyrrolidon?
N-(2-Hydroxyethyl)-2-pyrrolidon CAS 3445-11-2 yog cov kua tsis muaj tshuaj lom tsis muaj xim tsis muaj kuab paug nrog cov kuab tshuaj zoo heev thiab tshuaj lom neeg ruaj khov, tsis muaj nplaim taws, hygroscopic me ntsis thiab tsis muaj kev pheej hmoo ntawm tus kheej-polymerization nyob rau hauv ib txwm cia.
N-(2-Hydroxyethyl)-2-pyrrolidon nta dual hydroxyl-pyrrolidone polar pawg rau universal dissolution kev ua tau zoo; zoo compatibility nrog organic / inorganic tshuaj, siab purity kom ruaj khov khoom zoo, nqi-zoo rau hnyav thiab nruab nrab daim ntaub ntawv nrog tsawg volatility thiab dav kev khiav hauj lwm kub ntau yam.
