Mea Hana Maikaʻi Kumukuai N,N-DIMETHYLFORMAMIDE(DMF) CAS 68-12-2

ʻO DMF kahi mea hoʻoheheʻe maikaʻi no nā ʻano polymers kiʻekiʻe e like me ka polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, a me nā mea ʻē aʻe, a hiki ke hoʻohana ʻia no ka wili pulu o nā fibers synthetic e like me ka polyacrylonitrile fibers, a me ka synthesis o polyurethane; Hoʻohana ʻia no ka hana kiʻiʻoniʻoni plastik; hiki ke hoʻohana ʻia ma ke ʻano he pena kala no ka wehe ʻana i ka pena; hiki iā ia ke hoʻoheheʻe i kekahi mau puaʻa haʻahaʻa haʻahaʻa, i loaʻa i nā puaʻa nā ʻano o nā mea pena. Hoʻohana ʻia ʻo DMF no ka unuhi ʻana a me ka hoʻokaʻawale ʻana a me ka hoʻihoʻi ʻana o ka butadiene mai nā hakina C4 a me ka isoprene mai nā hakina 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 ka koho maikaʻi no ka solubility o ka waikawa isophthalic a me ka waikawa terephthalic: ʻoi aku ka maʻemaʻe o ka isophthalic acid i DMF ma mua o ka terephthalic acid, solvent extraction a hapa Crystallization, hiki ke hoʻokaʻawale ʻia nā mea ʻelua. I ka ʻoihana petrochemical, hiki ke hoʻohana ʻia ka DMF ma ke ʻano he mea hoʻoheheʻe kinoea e hoʻokaʻawale a hoʻomaʻemaʻe i nā kinoea. Ma ke ʻano he lāʻau lapaʻau no ka holoi ʻana i ka Chemicalbook i ka ʻoihana polyurethane, hoʻohana nui ʻia i ka hana ʻana i ka ʻili synthetic pulu; ma ke ʻano he mea hoʻoheheʻe i loko o ka ʻoihana fiber acrylic, hoʻohana nui ʻia i ka hana ʻana i ka wili maloʻo o ka fiber acrylic; i loko o ka 'oihana uila e like me ka quenching o ka tin-plated 'āpana a me kaapuni papa 'ē aʻe 'oihana e lawe i ka pilikia kinoea, solvents no ka lāʻau crystallization, adhesives, etc. I ka organic reactions, DMF ole wale hoʻohana 'ia e like me ka'ūheheʻe no ka pane, akā, he mea koʻikoʻi waena ma ka organic synthesis. I ka ʻoihana pesticide, hiki ke hoʻohana ʻia e hana i ka ciprofloxacin; i ka ʻoihana lāʻau lapaʻau, hiki ke hoʻohana ʻia e synthesize iodine, doxycycline, cortisone, vitamin B6, iodine, quercetin, pyrantel, N-formylsarcomin, Oncoline, methoxyfen, benzodiazepine, cyclohexyl nitrosourea, furoflurouracil, hemostatic acid, bepartame chloriraminevita, bepartylame, methoxyfen, benzodiazepine. Hana ʻia. He hopena catalytic ka DMF i nā hopena o ka hydrogenation, dehydrogenation, dehydration a me ka dehydrohalogenation, no laila e hoʻohaʻahaʻa ʻia ka mahana hopena a hoʻomaikaʻi ʻia ka maʻemaʻe o ka huahana.

1. He mea hoʻoheheʻe organik maikaʻi loa ia, i hoʻohanaʻia ma keʻano he mea hoʻoheheʻe no ka polyurethane, polyacrylonitrile, a me ka polyvinyl chloride, a hoʻohanaʻia hoʻi ma keʻano he extractant, ma keʻano he mea maka no nā lāʻau lapaʻau a me nā pesticides.

2. Hoʻohana ʻia e like me ka analytical reagent a me ka solvent no ka vinyl resin a me ka acetylene

3. ʻAʻole ia he mea hoʻohana kemika wale nō me ka nui o ka hoʻohana ʻana, akā he mea hoʻoheheʻe maikaʻi loa me ka nui o nā hoʻohana. ʻO DMF kahi mea hoʻoheheʻe maikaʻi no nā ʻano polymers kiʻekiʻe e like me ka polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, a me nā mea ʻē aʻe, a hiki ke hoʻohana ʻia no ka wili pulu o nā fibers synthetic e like me ka polyacrylonitrile fibers, a me ka synthesis o polyurethane; Hoʻohana ʻia no ka hana kiʻiʻoniʻoni plastik; hiki ke hoʻohana ʻia ma ke ʻano he pena kala no ka wehe ʻana i ka pena; hiki iā ia ke hoʻoheheʻe i kekahi mau puaʻa haʻahaʻa haʻahaʻa, i loaʻa i nā puaʻa nā ʻano o nā mea pena. Hoʻohana ʻia ʻo DMF no ka unuhi ʻana a me ka hoʻokaʻawale ʻana a me ka hoʻihoʻi ʻana o ka butadiene mai nā hakina C4 a me ka isoprene mai nā hakina 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 ka koho maikaʻi no ka solubility o ka waikawa isophthalic a me ka waikawa terephthalic: ʻoi aku ka maʻalahi o ka waika isophthalic i DMF ma mua o ka waikona terephthalic, lawe ʻia ka hoʻoheheʻe ʻana i loko o ka dimethyl chemicalbook acid formamide A i ʻole i hoʻokaʻawale ʻia, hiki ke hoʻokaʻawale ʻia nā mea ʻelua. I ka ʻoihana petrochemical, hiki ke hoʻohana ʻia ka DMF ma ke ʻano he mea hoʻoheheʻe kinoea e hoʻokaʻawale a hoʻomaʻemaʻe i nā kinoea. I loko o nā mea kūlohelohe, ʻaʻole hoʻohana nui ʻia ʻo DMF ma ke ʻano he solvent no ka hopena, akā he mea 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 iodine, doxycycline, cortisone, vitamin B6, iodine, quercetin, pyrantel, N-formylsarcomin, Tumorine, Methoxyfen mustard, Bian nitrogen mustard, cyclohexyl nitrosourea, furoflurouracil, hemomestatic acid, betrolamine. Loaʻa ka hopena catalytic i nā hopena o ka hydrogenation, dehydrogenation, dehydration a me ka dehydrohalogenation, no laila e hoʻohaʻahaʻa ʻia ka mahana hopena a hoʻomaikaʻi ʻia ka maʻemaʻe o ka huahana.

4. Non-aqueous titration solvent. Mea hoʻoheheʻe no ka vinyl a me ka acetylene. Hoʻoholo kiʻi kiʻi. ʻO ke kinoea chromatographic stationary solution (ʻoi loa ka wela o ka hana 50 ℃, he methanol ka mea hoʻoheheʻe), hoʻokaʻawale ʻana i ka puke Kimia C2 ~ C5 hydrocarbons, a hiki ke hoʻokaʻawale i ka maʻamau, isobutene a me cis, trans-2-butene. Ka nānā ʻana i ke koena pesticide. Hoʻo·hui kino. ʻO ka hoʻohuihui peptide. No ka ʻoihana kiʻi.
