Kumukūʻai maikaʻi o ka mea hana N,N-DIMETHYLFORMAMIDE (DMF) CAS 68-12-2

He mea hoʻoheheʻe maikaʻi ʻo DMF no nā ʻano polymers kiʻekiʻe e like me ka polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, a pēlā aku, a 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 ka ʻili plastik; hiki ke hoʻohana ʻia hoʻi ma ke ʻano he mea huki pena no ka wehe ʻana i ka pena; hiki iā ia ke hoʻoheheʻe i kekahi mau pigments haʻahaʻa-solubility, i loaʻa i nā pigments nā ʻano o nā dyes. Hoʻohana ʻia ʻo DMF no ka unuhi ʻala a me ka hoʻokaʻawale ʻana a me ka hoʻōla ʻana o ka butadiene mai nā ʻāpana C4 a me ka isoprene mai nā ʻāpana C5, a hiki ke hoʻohana ʻia 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 soluble o ka waikawa isophthalic i ka DMF ma mua o ka waikawa terephthalic, ka unuhi ʻana o ka solvent a i ʻole ka crystallization hapa, hiki ke hoʻokaʻawale ʻia nā mea ʻelua. I ka ʻoihana petrochemical, hiki ke hoʻohana ʻia ʻo DMF ma ke ʻano he mea hoʻomoʻa kinoea e hoʻokaʻawale a hoʻomaʻemaʻe i nā kinoea. Ma ke ʻano he mea hoʻōla no ka holoi ʻana i ka Chemicalbook i ka ʻoihana polyurethane, hoʻohana nui ʻia ia i ka hana ʻana o ka ʻili synthetic pulu; ma ke ʻano he mea hoʻoheheʻe i ka ʻoihana fiber acrylic, hoʻohana nui ʻia ia i ka hana milo maloʻo o ka fiber acrylic; i ka ʻoihana uila e like me ka quenching o nā ʻāpana tin-plated a me nā papa kaapuni. ʻO nā ʻoihana ʻē aʻe e komo pū me nā mea lawe o nā kinoea weliweli, nā mea hoʻoheheʻe no ka crystallization lāʻau, nā mea hoʻopili, a pēlā aku. I nā hopena organik, ʻaʻole hoʻohana nui ʻia ʻo DMF ma ke ʻano he mea hoʻoheheʻe no ka hopena, akā he mea waena koʻikoʻi hoʻi i ka synthesis organik. I ka ʻoihana pesticide, hiki ke hoʻohana ʻia e hana i ka ciprofloxacin; i ka ʻoihana lāʻau lapaʻau, hiki ke hoʻohana ʻia e synthesize i ka iodine, doxycycline, cortisone, vitamin B6, iodine, quercetin, pyrantel, N-formylsarcomin, Oncoline, methoxyfen, benzodiazepine, cyclohexyl nitrosourea, furoflurouracil, hemostatic acid, bepartame, megestrol, bilevita, chlorpheniramine, sulfonamides Production. Loaʻa iā DMF kahi hopena catalytic i nā hopena o ka hydrogenation, dehydrogenation, dehydration a me dehydrohalogenation, i hoʻohaʻahaʻa ʻia ka mahana o ka hopena a hoʻomaikaʻi ʻia ka maʻemaʻe o ka huahana.

1. He mea hoʻoheheʻe organik maikaʻi loa ia, i hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe no ka polyurethane, polyacrylonitrile, a me ka polyvinyl chloride, a hoʻohana pū ʻia hoʻi ma ke ʻano he mea unuhi, ma ke ʻano he mea maka no nā lāʻau lapaʻau a me nā pesticides.

2. Hoʻohana ʻia ma ke ʻano he reagent analytical a me ka solvent no ka vinyl resin a me ka acetylene

3. ʻAʻole wale ia he mea maka kemika me nā ʻano hoʻohana like ʻole, akā he mea hoʻoheheʻe maikaʻi loa me nā ʻano hoʻohana like ʻole. He mea hoʻoheheʻe maikaʻi ʻo DMF no nā ʻano polymers kiʻekiʻe e like me ka polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, etc., a 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 ma ke ʻano he mea huki pena no ka wehe ʻana i ka pena; hiki iā ia ke hoʻoheheʻe i kekahi mau pigments haʻahaʻa-solubility, i loaʻa i nā pigments nā ʻano o nā dyes. Hoʻohana ʻia ʻo DMF no ka unuhi ʻala a me ka hoʻokaʻawale ʻana a me ka hoʻōla ʻana o ka butadiene mai nā ʻāpana C4 a me ka isoprene mai nā ʻāpana C5, a hiki ke hoʻohana ʻia ma ke ʻano he reagent maikaʻi 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 soluble o ka waikawa isophthalic i ka DMF ma mua o ka waikawa terephthalic, lawe ʻia ka unuhi solvent i loko o ka dimethyl chemicalbook acid formamide A i ʻole ka crystallized hapa, hiki ke hoʻokaʻawale ʻia nā mea ʻelua. I ka ʻoihana petrochemical, hiki ke hoʻohana ʻia ʻo DMF ma ke ʻano he mea hoʻomoʻa kinoea e hoʻokaʻawale a hoʻomaʻemaʻe i nā kinoea. I nā hopena organik, ʻaʻole hoʻohana nui ʻia ʻo DMF ma ke ʻano he solvent no ka hopena, akā he mea nui hoʻi i ka synthesis organik. I ka ʻoihana pesticide, hiki ke hoʻohana ʻia e hana i ka ciprofloxacin; I loko o ka ʻoihana lāʻau lapaʻau, hiki ke hoʻohana ʻia e synthesize i ka iodine, doxycycline, cortisone, vitamin B6, iodine, quercetin, pyrantel, N-formylsarcomin, Tumorine, Methoxyfen mustard, Bian nitrogen mustard, cyclohexyl nitrosourea, furoflurouracil, hemostatic acid, bepartame, megestrol, bilevitamin, chlorpheniramine, etc. Loaʻa i ka DMF kahi hopena catalytic i nā hopena o ka hydrogenation, dehydrogenation, dehydration a me dehydrohalogenation, i hoʻohaʻahaʻa ʻia ka mahana o ka hopena a hoʻomaikaʻi ʻia ka maʻemaʻe o ka huahana.

4. Mea hoʻoheheʻe titration ʻaʻole wai. Mea hoʻoheheʻe no ka vinyl a me ka acetylene. Hoʻoholo photometric. Hoʻonā paʻa chromatographic gas (ka mahana hana kiʻekiʻe loa 50 ℃, ʻo ka mea hoʻoheheʻe he methanol), hoʻokaʻawale Chemicalbook analysis C2 ~ C5 hydrocarbons, a hiki ke hoʻokaʻawale i ka maʻamau, isobutene a me cis, trans-2-butene. Ka nānā ʻana i nā koena pesticide. Organic Synthesis. Peptide synthesis. No ka ʻoihana kiʻi paʻi kiʻi.
