ʻO ka huahana maʻemaʻe N-methylformamide he wai ʻole kala, moakāka a mānoanoa hoʻi, mp-3.8℃, bp198℃, n25D1.43Chemicalbook10, ka nui pili 0.9986 (25℃), hiki ke hoʻoheheʻe ʻia i ka wai, a hiki ke hoʻoheheʻe i nā paʻakai inorganic. Loaʻa iā ia ka Hygroscopic, maʻalahi ke palaho i nā hopena acidic a alkaline paha.

Hoʻohana:

He mea koʻikoʻi ka N-methylformamide i ka synthesis o nā pesticides, insecticides a me nā acaricides monoformamidine a me diformamidine. Hoʻohana ʻia nō hoʻi i ka hana ʻana i nā lāʻau lapaʻau, ka ʻili synthetic, ka ʻili artificial a me ke ʻano he solvent no nā lole fiber kemika.

ʻano hana

Ua loaʻa ke ʻano methylamine mai ka pilina ma waena o ka methylamine a me ke kalapona monoxide. CO+CH3NH2→HCONHCH3 E hoʻolako i 87.05kg/h, ʻoiai e hoʻolako ana i 56.5kg/h o ke kalapona monoxide me ka ʻike o 9.5%, ʻo ka mahana o ka hopena he 90°C, a ʻo ke kaomi he 2.53MPa. E lawe i waho i 140.75kg o ka hui ʻana me 80.5% (hapa nui) o ka monomethylamine i kēlā me kēia hola, ʻo ia hoʻi, ʻo ka nui o ka hana ʻana o N-methylformamide he 113.4kg i kēlā me kēia hola, a ʻo ka hiki ke hana o ka reactor 1L he 1.89kg N-methylformamide i kēlā me kēia hola.
