Izakhiwo zamakhemikhali:

Umkhiqizo omsulwa we-N-methylformamide uketshezi olungenambala, olubonakalayo noluqinile, mp-3.8℃, bp198℃, n25D1.43Chemicalbook10, ukuminyana okuhlobene okungu-0.9986 (25℃), oncibilikayo emanzini, futhi ungancibilikisa nosawoti ongaphili. Une-Hygroscopic, ubola kalula ezixazululweni ezine-acidic noma ze-alkaline.

Ukusetshenziswa:

I-N-methylformamide iyinto ebalulekile yokwenziwa kwezinto eziphilayo. Isetshenziswa ekuhlanganiseni izibulala-zinambuzane, izibulala-zinambuzane kanye ne-acaricides i-monoformamidine kanye ne-diformamidine. Iphinde isetshenziswe ekukhiqizeni imithi, isikhumba sokwenziwa, isikhumba sokwenziwa kanye nesinyibilikisi sezindwangu zefayibha yamakhemikhali.

indlela yokukhiqiza

Indlela ye-methylamine isuselwa ekusebenzisaneni phakathi kwe-methylamine ne-carbon monoxide. I-CO+CH3NH2→HCONHCH3 Ihlinzeka ngo-87.05kg/h, ngenkathi ihlinzeka ngo-56.5kg/h we-carbon monoxide enokuqukethwe okungu-9Chemicalbook9.5%, izinga lokushisa lokusabela lingu-90°C, kanti ingcindezi ingu-2.53MPa. Khipha u-140.75kg wengxube equkethe u-80.5% (ingxenye enkulu) we-monomethylamine njalo ngehora, okungukuthi, inani lokukhiqiza le-N-methylformamide lingu-113.4kg ngehora, kanti amandla okukhiqiza e-reactor engu-1L angu-1.89kg N-methylformamide ngehora.
