N-Methyldiethanolamine Siv Thiab Synthesis

Chemical Properties	N-Methyldiethanolamine (MDEA) yog xim tsis muaj xim rau daj kua nplaum nrog cov ntxhiab tsw zoo li ammonia. Nws yog kiag li soluble nyob rau hauv dej. N-Methyldiethanolamine yog ib qho alkyl alkanolamine.Nws ua ke cov yam ntxwv ntawm ob qho tib si amines thiab cawv kom nws muaj peev xwm ua rau muaj kev cuam tshuam ntawm ob qho tib si cawv thiab amines: tsim quaternary amine ntsev, xab npum, thiab esters.
Siv	N-methyldiethanolamine yog siv los ua ib qho nruab nrab hauv kev sib txuas ntawm ntau yam khoom. Nws cov chemistry tshwj xeeb tau ua rau nws siv ntau qhov chaw, suav nrog cov txheej txheem, cov khoom siv roj nplua nyeem, polishes, tshuaj ntxuav tes, tshuaj tua kab, cov khoom tu tus kheej, tshuaj, tshuaj urethane catalysts, thiab tshuaj kho dej. Nws kuj yog siv rau hauv kev nqus cov kua qaub gases, catalyst rau polyurethane foams, pH tswj tus neeg saib xyuas.
Siv	N-Methyldiethanolamine yog reagent siv los tiv thaiv boronic acids li N-methyl-O, O-diethanolamine esters.
Kev npaj	N-methyldiethanolamine yog tsim los ntawm cov tshuaj tiv thaiv ntawm ethylene oxide thiab methylamine.
Synthesis Reference (cov)	Phau ntawv Journal of the American Chemical Society, 107, p. 6659, 1985 ibDOI:10.1021/j00309a039
Kev piav qhia dav dav	Cov kua dej tsis muaj xim.
Cua & Dej Reactions	Soluble dej heev.
Reactivity Profile	N-Methyldiethanolamine yog ib qho aminoalcohol. Amines yog cov khoom siv tshuaj. Lawv neutralize acids tsim cov ntsev ntxiv rau dej. Cov tshuaj tiv thaiv acid-base no yog exothermic. Tus nqi ntawm tshav kub uas hloov zuj zus mus rau ib mole ntawm amine nyob rau hauv ib tug neutralization yog feem ntau ywj siab ntawm lub zog ntawm amine raws li ib tug puag. Amines yuav tsis sib haum nrog isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, thiab acid halides. Flammable gaseous hydrogen yog tsim los ntawm amines ua ke nrog cov muaj zog txo cov neeg ua haujlwm, xws li hydrides. N-Methyldiethanolamine yuav hnov mob nrog oxidizing cov ntaub ntawv.
Health Hazard	Kev nthuav tawm tuaj yeem ua rau khaus ntawm qhov muag, qhov ntswg thiab caj pas.
Hluav Taws Xob	Kev phom sij tshwj xeeb ntawm Cov Khoom Siv Hluav Taws Xob: Ua kom khaus vapors thiab cov pa roj carbon monoxide, xws li nitrogen oxides thiab carbon monoxide, tuaj yeem tsim thaum muaj hluav taws kub.
Flammability thiab Explosibility	Tsis yog nplaim taws
Environmental Fate	N-methyldiethanolamine tau yooj yim biodegradable, thiab nws cov peev xwm bioconcentration tsawg. Kev tso tawm rau ib puag ncig yuav tsis mob thiab yuav degrade sai. Lub peev xwm rau kev txav mus los hauv av yog siab heev. Nws yog me ntsis tshuaj lom rau cov kab mob hauv dej ntawm qhov mob hnyav.
khaws cia	N-methyldiethanolamine yog ruaj khov nyob rau hauv ib txwm cia thiab siv tej yam kev mob, tab sis siab kub yuav ua rau nws decompose. Cov khoom decomposition nyob ntawm qhov kub thiab txias, huab cua, thiab muaj lwm yam khoom siv. Tsis txhob sib cuag nrog nitrites, muaj zog acids, thiab muaj zog oxidizers. Tsis txhob xav txog kev sib cuag nrog halogenated hydrocarbons. N-methyldiethanolamine tuaj yeem hnov mob nrog halogenated organics, ua rau kub thiab / lossis siab nce. Nws yog corrosive thaum ntub. Cov cua kub siab tshaj 60 degree (140 degree F) nyob rau hauv lub xub ntiag ntawm txhuas tuaj yeem ua rau corrosion thiab tsim cov roj hydrogen flammable.
