Dimethylamide/ DimethylFormamide
Hoʻohana:ʻO Dimethylamide (DMF) kahi mea maka kemika koʻikoʻi a me ka mea hoʻoheheʻe hana kiʻekiʻe, i hoʻohana nui ʻia i nā ʻoihana e like me ka polyurethane, acrylic, pharmaceuticals, pesticides, dyes, electronics, etc. Ma ke ʻano he mea holoi a hoʻōla i ka ʻoihana polyurethane, hoʻohana nui ʻia ia i ka hana ʻana o ka ʻili synthetic pulu; Ma ke ʻano he mea waena lāʻau lapaʻau synthetic i ka ʻoihana lāʻau lapaʻau, hoʻohana nui ʻia ia i ka hana ʻana o nā lāʻau doxycycline, cortisone, a me sulfonamide; Ma ke ʻano he mea hoʻoheheʻe i ka ʻoihana fiber acrylic, hoʻohana nui ʻia ia no ka hana wili maloʻo o nā fiber acrylic; Hoʻohana ʻia i ka ʻoihana pesticide e synthesize i nā insecticides pesticide maikaʻi a haʻahaʻa ka ʻona; Hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe dye i ka ʻoihana dye; Ke kinai ʻana i nā ʻāpana tinned a me ka hoʻomaʻemaʻe ʻana i nā papa kaapuni i ka ʻoihana electronics; ʻO nā ʻoihana ʻē aʻe e pili ana i nā mea lawe o nā kinoea weliweli, nā mea hoʻoheheʻe no ka crystallization lāʻau, nā adhesives, etc.
Inoa kemika: N, N-dimethylacetamide
ʻO Dimethylacetamide kahi mea hoʻoheheʻe polar ikaika ʻole protonated hiki ke hoʻoheheʻe i nā hui like ʻole a hui pū ʻia me ka wai, nā ethers, ketones, esters, a me nā mea ʻē aʻe. Loaʻa iā ia ke kūpaʻa wela kiʻekiʻe, ke kū'ē hydrolysis haʻahaʻa, ka pala haʻahaʻa, a me ka ʻawaʻawa haʻahaʻa. Loaʻa iā ia ka solubility maikaʻi no nā resins like ʻole, ʻoiai ka resin polyurethane a me ka resin polyimide, a hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe no nā olonā synthetic pale wela, nā kiʻiʻoniʻoni plastik, nā uhi, nā lāʻau lapaʻau, a me ka milo acrylonitrile. ʻO Dimethylacetamide, ma ke ʻano he mea hoʻohaʻahaʻa haʻahaʻa, kahi paila kiʻekiʻe, a me ka polarity kiʻekiʻe non proton solvent a me ka chemical intermediate, hoʻohana nui ʻia ma nā kahua e like me nā mea synthetic, nā lāʻau lapaʻau, nā pesticides, nā olonā kemika, ka hana ʻaila, a me nā pigments organik.
He aha nā hoʻohana nui o ka dimethyl formamide?
01hoʻohana ʻia ma ke ʻano he reagent analytical a me ka solvent no ka ethylene resin a me ka acetylene
02he mea hoʻoheheʻe organik maikaʻi loa i hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe no ka polyurethane, polyacrylonitrile, a me ka polyvinyl chloride, a me he mea maka no nā mea unuhi, nā lāʻau lapaʻau, a me nā pesticides e like me imidacloprid
03ʻAʻole wale ka Dimethylformamide he mea maka kemika i hoʻohana nui ʻia, akā he mea hoʻoheheʻe maikaʻi loa hoʻi me nā ʻano hoʻohana like ʻole. He mea hoʻoheheʻe maikaʻi ʻo Dimethylformamide no nā polymers kiʻekiʻe like ʻole e like me ka polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, etc. Hiki ke hoʻohana ʻia no ka milo pulu o nā olonā synthetic e like me nā olonā polyacrylonitrile a me ka synthesis o ka polyurethane; Hoʻohana ʻia no ka hana ʻana i nā kiʻiʻoniʻoni plastik; Hiki ke hoʻohana ʻia hoʻi ma ke ʻano he mea wehe pena no ka wehe ʻana i ka pena; Hiki iā ia ke hoʻoheheʻe i kekahi mau pigments solubility haʻahaʻa, e hāʻawi ana iā lākou i nā ʻano o nā dyes. Hoʻohana ʻia ʻo Dimethylformamide no ka unuhi ʻana i ka hydrocarbon aromatic, a no ka hoʻokaʻawale ʻana a me ka hoʻihoʻi ʻana i ka butadiene mai ka hapa C4 a me ka isoprene mai ka hapa C5. Hiki ke hoʻohana ʻia hoʻi ma ke ʻano he reagent kūpono no ka hoʻokaʻawale ʻana i nā ʻāpana non hydrocarbon mai ka paraffin. Loaʻa iā ia ke koho maikaʻi no ka solubility o ka waikawa isophthalic a me ka waikawa terephthalic: ʻoi aku ka nui o ka solubility o ka waikawa isophthalic i loko o ka dimethylformamide ma mua o ka waikawa terephthalic. Hiki i ka unuhi ʻana o ka solvent a i ʻole ka crystallization hapa i loko o ka dimethylformamide ke hoʻokaʻawale i nā mea ʻelua. I loko o ka ʻoihana petrochemical, hiki ke hoʻohana ʻia ka dimethyl formamide ma ke ʻano he mea hoʻomoʻa kinoea no ka hoʻokaʻawale ʻana a me ka hoʻomaʻemaʻe ʻana i nā kinoea. I nā hopena organik, ʻaʻole hoʻohana nui ʻia ka dimethylformamide ma ke ʻano he solvent, akā he mea nui hoʻi i ka synthesis organik. Hiki ke hoʻohana ʻia e hana i nā chlorpyrifos i loko o ka ʻoihana pesticide; I loko o ka ʻoihana lāʻau lapaʻau, hiki ke hoʻohana ʻia e synthesize iodide pyrimidine, doxycycline, cortisone, vitamin B6, iodoside, Qubijing, thiapyrimidine, N-formyl sarcolysin, antineoplastic acid, methoxyaromaine, bianzapine, cyclohexanone nitrourea, furfururacil, hemostatic acid, Fenfenmethasone, medroxyprogesterone, biliveratrol, chlorpheniramine, a pēlā aku. Hoʻokani ʻo Dimethylformamide i kahi hana catalytic i ka hydrogenation, dehydrogenation, dehydration, a me nā hopena dehalogenation, e hōʻemi ana i ka mahana o ka hopena a hoʻomaikaʻi i ka maʻemaʻe o ka huahana.
04ʻO ka reagent titration solution ʻole aqueous, solvent no ka ethylene resin a me ka acetylene, synthesis organik, photometry, gas chromatography stationary phase (ka mahana hana kiʻekiʻe loa 50 ℃, solvent methanol), ka hoʻokaʻawale ʻana a me ka nānā ʻana o nā hydrocarbons C2-C5, a me ka hiki ke hoʻokaʻawale i ka maʻamau, isobutene, cis, a me ka trans butene. Ka nānā ʻana i nā koena pesticide. Synthesis organik. Synthesis peptide. Hoʻohana ʻia i ka ʻoihana kiʻi paʻi kiʻi.
