N,N-Dimethylacetamide (DMAc) yog xim tsis muaj xim, siab- boiling, polar aprotic solvent nrog lub boiling point ntawm kwv yees li 165℃(329-330℃F) thiab ib tug melting point ntawm -20℃(-4℃F). Nws yog siv nyob rau hauv ntau yam kev lag luam, nrog rau kev tsim cov hluavtaws fibers, plastics, pharmaceuticals, thiab electronics.
DMACyog ib tug polar solvent uas yog miscible nrog dej, cawv, ethers, thiab ntau organic solvents. Nws muaj qhov kub ntawm 165-166 degree, ua rau nws muaj txiaj ntsig rau siab - qhov kub thiab txias cov txheej txheem distillation.

Kev txiav txim siab txog kev nyab xeeb ntawm N, N-Dimethylacetamide (DMAc)
DMAC raug cais raws li cov tshuaj lom thiab muaj kev phom sij los ntawm ntau lub koom haum tswj hwm, suav nrog US Environmental Protection Agency (EPA) thiab European Chemicals Agency (ECHA). Nws tuaj yeem ua rau tawv nqaij thiab qhov muag khaus, ua pa thiab plab hnyuv, thiab ua rau muaj menyuam thiab kev loj hlob toxicity. Ntev ntev lossis rov ua dua rau DMAC kuj tseem tuaj yeem ua rau lub siab thiab lub raum puas, thiab ua rau muaj kev pheej hmoo ntawm mob qog noj ntshav.
Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau ua raws li DMAC nrog kev ceev faj kom tsim nyog, xws li hnav khaub ncaws tiv thaiv, hnab looj tes, thiab tsom iav, siv lub tshuab ua pa kom txaus thiab ntim khoom, thiab zam kev sib cuag ncaj qha thiab noj. DMAC tseem yuav tsum tau muab khaws cia thiab thauj mus rau hauv qhov chaw txias, qhuav, thiab qhov chaw zoo - qhov cua, nyob deb ntawm qhov chaw kub, qhov hluav taws kub, thiab cov khoom siv tsis sib xws.
