N,N-Dimethylformamide DMF tshuaj ua li cas?
DMF yog tsim los ntawm cov tshuaj tiv thaiv catalytic ntawm dimethylamine thiab carbon monoxide nyob rau hauv siab thiab kub. Cov txheej txheem no yuav tsum tau ua tib zoo saib xyuas thiab kev tswj xyuas kom ntseeg tau tias qhov purity thiab zoo ntawm cov khoom.
(CH₃)₂NH + CO → (CH₃)₂NCHO
