3-Methylamino-1, 2-propanediol Siv Thiab Synthesis

Kev piav qhia	3-Methylamino-1, 2-propanediol (MAPD) yog cov kua ntshiab nrog cov tshuaj formula C₄H₁₁TSIS MUAJ₂. Nws tuaj yeem raug tsim los ntawm allylamine thiab alkanolamine los ntawm cov txheej txheem thermal. Nws reacts nrog chloride los tsim methyl chloroacetate, uas tuaj yeem hloov mus rau hauv 3-methylamino-1, 2-propanediol los ntawm cov tshuaj tiv thaiv methanol. Cov txheej txheem tsim khoom rau cov khoom no tau pom tias tsim kom muaj cov khoom phom sij tsawg xws li polycyclic aromatic hydrocarbons (PAHs) thiab dioxins.
Chemical Properties	clear colorless mus rau daj ntseg viscous kua
Siv	3-Methylamino-1, 2-propanediol yog ib qho reactive compound uas yog siv nyob rau hauv synthesis ntawm organic acids. Nws kuj yog siv los ua ib qho nruab nrab hauv kev tsim cov polyethylene glycols thiab particle coatings.
Txhais	ChEBI: 3-methylamino-1, 2-propanediol yog ib qho amine thib ob.
Kev npaj	3-Methylamino-1, 2-propanediol (MAPD) yog synthesized los ntawm reacting 3-chloro-1,2-propanediol (CPD) nrog monomethyl amine nyob rau hauv alkaline ib puag ncig los ntawm kev ntxiv sodium hydroxide. Tom qab ntawd, cov khoom tau dhau los ua cov kauj ruam ua kom huv. N-Methyl-1-amino-2, 3-propandiol (45A) Methylamine (172ml ntawm 40}% daws hauv dej, 2 mol) tau txias rau {{13} } degree thiab 2,{{10}}epoxy-1-propanol (25g, 0.34mol) tau ntxiv ntawm tus nqi kom tswj qhov kub ntawm lossis qis dua 10 degree . Qhov sib tov yog stirred rau 3 teev ntawm 0 degree. Tshaj methylamine thiab dej tau evaporated nyob rau hauv vacuo thiab cov khoom raug purified los ntawm distillation ntawm 103-105 degree, ntawm 0.5 mm Hg, muab cov compound 3-Methylamino-1, 2-propanediol .
