N-methylacetamide yog cov siv lead ua dawb zoo li koob lossis cov kua pob tshab tsis muaj xim. Daim ntawv tshwj xeeb yuav txawv nyob ntawm qhov kub thiab txias, siab thiab lwm yam xwm txheej.

Cov khoom siv lub cev: Cov mis molecular ntawm N-methylacetamide yog C3H7NO, thiab qhov hnyav molecular yog 73.09. Nws lub ntsiab lus yaj feem ntau yog ntawm 26-28 ° C, thiab nws lub ntsiab lus kub yog 204 ~ 206 ° C. Nws muaj cov dej zoo solubility thiab qhov ceev ntawm 0.9571 ntawm 25 ° C. Tsis tas li ntawd, nws lub ntsiab lus flash yog 108 ° C, qhia tias cov tshuaj yuav flammable ntawm qhov kub siab dua.
Cov khoom siv tshuaj lom neeg thiab kev siv: N-methylacetamide ruaj khov hauv tshuaj, tsis yooj yim rau decompose, thiab muaj peev xwm zoo los yaj lwm cov tshuaj. Nws feem ntau siv ua cov organic solvent thiab tuaj yeem siv ua cov khoom nruab nrab hauv kev tsim cov organic xws li tshuaj tua kab thiab tshuaj. Hauv kev lag luam tsim tshuaj, N-methylacetamide kuj yog cov khoom siv raw khoom siv feem ntau, xws li kev tsim cov tshuaj cephalosporins.

Hauv kev xaus lus, N-methylacetamide feem ntau yog nyob rau hauv daim ntawv ntawm cov siv lead ua dawb zoo li koob lossis cov kua tsis muaj xim pob tshab. Nws muaj ntau yam khoom siv lub cev thiab tshuaj lom neeg thiab siv dav hauv kev tsim cov organic thiab kev tsim tshuaj.

Cov kev siv ntawm N-methylacetamide

Cov kuab tshuaj organic: N-methylacetamide yog cov kua tsis muaj xim thiab pob tshab ntawm chav tsev kub thiab siab. Nws muaj cov dej yaj zoo thiab yog cov kuab tshuaj organic nrog kev ruaj khov tshuaj zoo. Nws tsis yooj yim rau decompose thiab tuaj yeem yaj ntau yam tshuaj. Nws yog siv dav hauv cov tshuaj organic synthesis.

Kev sib xyaw ua ke ntawm cov organic: N-methylacetamide yog ib qho tseem ceeb ntawm kev sib xyaw ua ke ntawm cov organic. Nws tuaj yeem koom nrog ntau yam kev hloov pauv ntawm cov organic xws li alkylation, hydroxylation, thiab phosphation, thiab muab cov khoom siv raw tseem ceeb rau kev sib xyaw ua ke ntawm cov tshuaj tua kab, tshuaj, thiab lwm yam.

Cov Khoom Siv Ua Tshuaj: Hauv kev lag luam tsim tshuaj, N-methylacetamide yog cov khoom siv raw uas siv ntau, piv txwv li, nws yog siv los tsim cov tshuaj tua kab mob cephalosporin. Hom tshuaj tua kab mob no muaj cov yam ntxwv ntawm cov tshuaj tua kab mob thiab muaj zog tua kab mob, thiab siv dav hauv kev kho mob.

Hauv kev xaus, N-methylacetamide muaj cov ntawv thov tseem ceeb hauv cov organic solvents, organic synthesis intermediates, thiab cov ntaub ntawv raw khoom tsim tshuaj
