Kev Siv Khoom Siv Hluav Taws Xob DMF:
CAS 68-12-2 N,N-Dimethylformamide DMF yog ib qho tseem ceeb ntawm cov organic thiab cov kuab tshuaj zoo. Nws yog siv los ua hnyav rau txiv neej- ua tawv thiab tshuaj fiber ntau, kuj tseem siv los ua cov khoom siv rau kev sib txuas ntawm cov tshuaj tua kab ntawm siab -kev ua tau zoo thiab tsis muaj tshuaj lom, raws li cov pa nqus tau los cais thiab ntxuav cov roj hauv kev lag luam petrochemical, raws li cov khoom siv ntawm sulfadiazine, cortisone thiab vitamin B6 hauv kev lag luam tshuaj, thiab DMF kua hauv vaporse kuj yog ib qho tshuaj kho.
Cov ntaub ntawv kev nyab xeeb
1. Toxicity: N,N-Dimethylformamide muaj qee yam toxicity rau tib neeg. luv-lub sij hawm los yog ntev- lub sij hawm raug yuav ua rau lub cev ua pa, siab, thiab ob lub raum. Tsis tas li ntawd, DMF muaj peev xwm nqus tau los ntawm daim tawv nqaij.
