N, N-dimethylformamide | 68-12-2

ʻO N, N-dimethylformamide kahi mea hoʻoheheʻe polar aprotic maikaʻi loa e hiki ke hoʻoheheʻe i ka hapa nui o nā mea organik a me nā mea ʻole a hiki ke hui pū me ka wai, nā ʻawaʻawa, nā ethers, aldehydes, ketones, esters, halogenated hydrocarbons a aromatic hydrocarbons. .
Hoʻopuni ʻia ka hopena maikaʻi o ka mole N,N-dimethylformamide e nā pūʻulu methyl, e hana ana i kahi pale steric e pale ai i nā ion maikaʻi ʻole mai ka hoʻokokoke ʻana a pili wale me nā ion maikaʻi. ʻOi aku ka ʻoi aku o ka ʻeleʻele ma mua o nā anion solvated.
ʻOi aku ka maʻalahi o ka hoʻokō ʻana i nā hopena ionic he nui ma N,N-dimethylformamide ma mua o nā mea hoʻoheheʻe protic maʻamau, e like me ka pane ʻana o nā carboxylates a me nā hydrocarbons halogenated i N,N-dimethylformamide ma ke ana wela. Hiki iā ia ke hoʻoulu i nā esters i nā hua kiʻekiʻe a kūpono loa no ka synthesis o nā esters i hoʻopaʻa ʻia.
Hiki ke hoʻomākaukau ʻia ka N,N-dimethylformamide e ka hopena o ka formamide a me ka dimethylamine, a i ʻole ma ka hopena o kahi hopena methanol o dimethylamine a me carbon monoxide i mua o ka sodium alkoxide. N, N-dimethylformamide loaʻa nā waiwai hoʻoheheʻe maikaʻi no nā ʻano polymers like ʻole polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, etc., a hoʻohana nui ʻia i ka kiʻiʻoniʻoni plastik, pena, fiber a me nā ʻoihana ʻē aʻe; Hiki ke hoʻohana ʻia ma ke ʻano he mea pena e wehe i ka pena.

Pākē: 180KGS / Drum a i ʻole 200KGS / Drum a i ʻole kāu noi.
E mālama: E kūʻai ma kahi wahi maloʻo.
