xov xwm

N-methylmorpholine yog ib qho organic compound nrog cov mis mos molecular C5H11NO. Nws yog cov kua uas tsis muaj xim nrog cov ntxhiab tsw ntawm ammonia thiab rhiab rau huab cua. Nws yog miscible nrog dej, ethanol, benzene thiab ether; nws yog flammable, corrosive thiab me ntsis tshuaj lom. , muaj ib tug pungent tsw, thiab nqus tau pa vapor yog irritating rau ntawm daim tawv nqaij thiab mucous daim nyias nyias. LD50 1970 mg/kg. Qhov siab tshaj plaws tso cai nyob rau hauv huab cua yog 5 mg / m3.

[Packaging]: 180kg galvanized chim, kuj raws li tus neeg yuav tsum tau muaj.
[Siv]: Hauv kev lag luam polyurethane, N-methylmorpholine yog siv los ua cov khoom siv rau polyester polyurethane mos thaiv npuas. N-Methylmorpholine feem ntau yog siv los ua cov kuab tshuaj (cov kuab tshuaj zoo heev rau dyes, tyrosol, wax thiab shellac, thiab lwm yam), tus neeg sawv cev extraction, stabilizer rau chlorinated hydrocarbons, analytical reagents, catalysts, corrosion inhibitors, N-methylmorpholine Phenoline kuj tseem siv rau hauv cov synthesis ntawm roj hmab accelerators thiab lwm yam tshuaj zoo. N-methylmorpholine kuj tseem siv los ua polyurethane catalyst thiab catalyst rau synthesis ntawm ampicillin thiab hydroxybenzylpenicillin. N-methylmorpholine tuaj yeem tsim los ntawm oxidizing hydrogen peroxide. Nws yog spinning hnyav rau Lyocell (feem ntau hu ua Tencel) thiab Newcell artificial fibers, uas tam sim no hu ua "ntsuab fibers". Nws kuj tseem siv tau los ua cov kuab tshuaj. Kev tsim cov zaub casings.
[Storage]: kaw hauv qhov chaw txias thiab tsaus, qhov cua thiab qhuav ntawm qhov kub tsawg; khaws cia cais los ntawm oxidants thiab acids.
