Taw qhia

N-Methylacetamide yog ib qho organic compound. Nws yog cov kua xim tsis muaj xim uas yog soluble hauv dej thiab ntau cov kuab tshuaj organic hauv chav tsev kub.

N-methylacetamide feem ntau yog siv rau hauv cov organic synthesis ua ib qho hnyav thiab nruab nrab. N-methylacetamide kuj tuaj yeem siv los ua tus neeg ua kom lub cev qhuav dej, tus neeg sawv cev ammonia, thiab carboxylic acid activator hauv cov tshuaj organic synthesis.

Kev npaj ntawm N-methylacetamide feem ntau tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm acetic acid nrog methylamine. Cov kauj ruam tshwj xeeb yog ua rau cov tshuaj acetic acid nrog methylamine ntawm molar piv ntawm 1: 1 nyob rau hauv cov xwm txheej tsim nyog, thiab tom qab ntawd distillation thiab purification kom tau txais cov khoom lag luam.

Cov ntaub ntawv kev nyab xeeb: Cov vapor ntawm N-methylacetamide tuaj yeem ua rau lub qhov muag thiab ua pa ua pa, thiab muaj qhov ua rau mob me me thaum sib cuag nrog daim tawv nqaij. Thaum siv lossis tuav, yuav tsum muaj kev tiv thaiv tus kheej, xws li hnav tsom iav tiv thaiv, hnab looj tes tiv thaiv, thiab lwm yam. N-methylacetamide kuj muaj tshuaj lom rau ib puag ncig, yog li nws yuav tsum ua raws li cov cai thiab kev tiv thaiv ib puag ncig thiab ua tib zoo saib xyuas. pov tseg kom raug. Thaum siv thiab khaws cia, yuav tsum ua raws li cov txheej txheem kev nyab xeeb thiab cov txheej txheem ua haujlwm.
