Aia ka N-methylacetamide ma ke ʻano o nā kristal keʻokeʻo e like me ke kui a i ʻole ka wai moakaka ʻole. Hiki ke ʻokoʻa ke ʻano kikoʻī ma muli o ka mahana, ke kaomi a me nā kūlana ʻē aʻe.

Nā ʻano kino: ʻO ke ʻano molekala o N-methylacetamide ʻo C3H7NO, a ʻo ke kaumaha molekala he 73.09. ʻO kona kiko heheʻe ma waena o 26-28°C, a ʻo kona kiko paila he 204 ~ 206°C. Loaʻa iā ia ka solubility maikaʻi i ka wai a me ka nui o 0.9571 ma 25°C. Eia kekahi, ʻo kona kiko lapalapa he 108°C, e hōʻike ana he hiki ke lapalapa ka mea i nā mahana kiʻekiʻe.
Nā waiwai kemika a me nā hoʻohana: He paʻa kemika ʻo N-methylacetamide, ʻaʻole maʻalahi ke palaho, a he hiki ke hoʻoheheʻe i nā hui ʻē aʻe. Hoʻohana pinepine ʻia ia ma ke ʻano he mea hoʻoheheʻe organik a hiki ke hoʻohana ʻia ma ke ʻano he waena i ka synthesis organik e like me nā pesticides a me nā lāʻau lapaʻau. I ka ʻoihana hana lāʻau lapaʻau, ʻo N-methylacetamide kekahi mea maka kumu i hoʻohana pinepine ʻia, e like me ka synthesis o nā molekala lāʻau cephalosporins.

I ka hōʻuluʻulu manaʻo, ʻo N-methylacetamide ke ʻano nui o nā kristal keʻokeʻo e like me ke kui a i ʻole ka wai aniani ʻole. Loaʻa iā ia nā ʻano kino a me nā kemika like ʻole a hoʻohana nui ʻia i ka synthesis organik a me ka hana lāʻau lapaʻau.

Nā hoʻohana ʻana o N-methylacetamide

Mea hoʻoheheʻe kūlohelohe: He wai ʻole kala a moakaka ka N-methylacetamide ma ka mahana o ka lumi a me ke kaomi. Loaʻa iā ia ka solubility maikaʻi i ka wai a he mea hoʻoheheʻe kūlohelohe me ke kūpaʻa kemika maikaʻi. ʻAʻole maʻalahi ka palaho a hiki ke hoʻoheheʻe i nā ʻano hui like ʻole. Hoʻohana nui ʻia ia i ka kemika synthesis organik.

‌Waena hana organik: He mea nui ka N-methylacetamide i ka hana organik. Hiki iā ia ke komo i nā ʻano hana organik like ʻole e like me ka alkylation, hydroxylation, a me ka phosphation, a hāʻawi i nā mea maka koʻikoʻi no ka hana organik o nā pesticides, nā lāʻau lapaʻau, a pēlā aku.

Nā mea maka hana lāʻau lapaʻau: I ka ʻoihana hana lāʻau lapaʻau, ʻo N-methylacetamide kahi mea maka maʻamau i hoʻohana ʻia, no ka laʻana, hoʻohana ʻia ia e synthesize i nā antibiotic cephalosporin. Loaʻa i kēia ʻano antibiotic nā ʻano o ka ʻōnaehana bactericidal a me ka hopena antibacterial ikaika, a hoʻohana nui ʻia i ka hana lapaʻau.

I ka hōʻuluʻulu manaʻo, he mau noi koʻikoʻi ko N-methylacetamide i nā mea hoʻoheheʻe organik, nā mea waena synthesis organik, a me nā mea hana lāʻau lapaʻau.
