Cov khoom siv tshuaj lom neeg:

N-methylformamide cov khoom ntshiab yog cov kua tsis muaj xim, pob tshab thiab viscous, mp-3.8 ℃, bp198 ℃, n25D1.43Chemicalbook10, qhov ceev ntawm qhov sib piv 0.9986 (25 ℃), soluble hauv dej, thiab tseem tuaj yeem yaj cov ntsev inorganic. Nws muaj Hygroscopic, yooj yim decomposes hauv cov kua qaub lossis alkaline.

Kev Siv:

N-methylformamide yog ib qho khoom siv tseem ceeb ntawm cov organic synthetic raw khoom. Nws yog siv rau hauv kev tsim cov tshuaj tua kab, tshuaj tua kab thiab acaricides monoformamidine thiab diformamidine. Nws kuj tseem siv rau hauv kev tsim tshuaj, tawv hluavtaws, tawv dag thiab ua cov kuab tshuaj rau cov ntaub fiber tshuaj.

txoj kev tsim khoom

Txoj kev methylamine yog los ntawm kev sib cuam tshuam ntawm methylamine thiab carbon monoxide. CO + CH3NH2 → HCONHCH3 Muab 87.05kg / h, thaum muab 56.5kg / h ntawm carbon monoxide nrog cov ntsiab lus ntawm 9Chemicalbook 9.5%, qhov kub ntawm cov tshuaj tiv thaiv yog 90 ° C, thiab qhov siab yog 2.53MPa. Tshem tawm 140.75kg ntawm cov khoom sib xyaw uas muaj 80.5% (feem pua ​​​​​​ntawm pawg) ntawm monomethylamine txhua teev, uas yog, qhov ntau ntawm N-methylformamide yog 113.4kg ib teev, thiab lub peev xwm tsim khoom ntawm 1L reactor yog 1.89kg N-methylformamide ib teev.
