Lub npe: N-ethylmorpholine.

Abbreviation: NEM.

Lub npe Askiv: N-ethylmorpholine.

Cov mis mos molecular yog C6H13NO thiab qhov hnyav molecular yog 115.2. CAS Nr .: 100-74-3

Tus qauv qauv:

Lub cev thiab tshuaj muaj zog

N-Ethylmorpholine yog cov xim tsis muaj xim rau cov kua daj me ntsis nrog cov viscosity (23 ° C) ntawm 2.3mPa.s, tus txheeb ze ntom ntom ntawm 0.916, qhov ntsuas tsis pom kev (23 ° C) ntawm 1.4415, qhov kub ntawm 138 ~ 139 ° C. , thiab qhov chaw khov ntawm -60 ~ -63 ℃, flash point (TCC) yog 32 ℃, vapor siab (20 ℃) ​​yog 813Pa. Soluble hauv dej, Pka = 7.8.

Khoom purity ≧98% lossis ≧99%, ya raws ≦0.5

Cov yam ntxwv thiab kev siv

Nws tuaj yeem siv los ua cov khoom siv hluav taws xob hauv PU thiab muaj ntxhiab tsw tsawg dua NMM. N-ethylmorpholine feem ntau yog siv los ua cov kuab tshuaj rau cov roj thiab cov resins, thiab tseem tuaj yeem siv los ua ib qho nruab nrab hauv cov organic synthesis. Tam sim no, qee lub tuam txhab xws li Air Products thiab Momentive zoo li tsis muab cov khoom no lawm.

N-ethylmorpholine thiab N-methylmorpholine yog nruab nrab-lub zog tertiary amine catalysts, tshwj xeeb tshaj yog tsim rau zus tau tej cov polyester-hom saj zawg zog polyurethane foams nrog zoo daim tawv nqaij tsim kev ua tau zoo. N-ethylmorpholine tseem tuaj yeem muaj qhov muaj zog catalytic ntawm cov tshuaj tiv thaiv gel tom qab ua npuas dej nce mus rau qhov siab tshaj plaws, nthuav cov hlwb mus rau qhov siab tshaj plaws. Ntxiv mus, cov tshuaj tiv thaiv foaming thiab gelation cov tshuaj tiv thaiv yuav tsis hloov pauv vim qhov sib txawv catalyst concentrations, tab sis qhov tsis zoo yog qhov tsw muaj zog.
