ʻO TianJia Mea Hana Hoʻohui Meaʻai Dimethylamide/Dimethylformamide
Hoʻohana:ʻO Dimethylamide (DMF) he mea waiwai nui kemika a me ka mea hoʻoheheʻe kiʻekiʻe, hoʻohana nui ʻia i nā ʻoihana e like me ka polyurethane, acrylic, pharmaceuticals, pesticides, dyes, electronics, etc. hoʻohana ʻia i ka hana ʻana i ka ʻili synthetic pulu;Ma keʻano he lāʻau lapaʻau synthetic ma waena o kaʻoihana lāʻau lapaʻau, hoʻohana nuiʻia i ka hanaʻana i nā lāʻau doxycycline, cortisone, a me sulfonamide;Ma ke ʻano he mea hoʻoheheʻe i ka ʻoihana fiber acrylic, hoʻohana nui ʻia no ka hana ʻana i ka wili maloʻo o nā fibers acrylic;Hoʻohana ʻia i ka ʻoihana pesticide e synthesize maikaʻi a haʻahaʻa haʻahaʻa i ka pesticide insecticides;Hoʻohana ʻia e like me ka mea hoʻoheheʻe wai i ka ʻoihana wai;Ke kinai ʻana i nā ʻāpana tinned a me ka hoʻomaʻemaʻe ʻana i nā papa kaapuni i ka ʻoihana uila;ʻO nā ʻoihana ʻē aʻe nā mea lawe i nā kinoea weliweli, nā mea hoʻoheheʻe no ka crystallization lāʻau lapaʻau, adhesives, etc.
Inoa kemika: N, N-dimethylacetamide
ʻO ka Dimethylacetamide kahi mea hoʻoheheʻe polar non protonated ikaika e hiki ke hoʻoheheʻe i nā pūhui like ʻole a hiki ke hui pū me ka wai, ethers, ketones, esters, a me nā mea ʻē aʻe.Loaʻa iā ia ka solubility maikaʻi no nā resins like ʻole, ʻoi aku ka polyurethane resin a me ka polyimide resin, a hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe no nā fiber synthetic pale wela, nā kiʻiʻoniʻoni plastik, nā uhi, nā lāʻau lapaʻau, a me ka wili acrylonitrile.ʻO Dimethylacetamide, ma ke ʻano he haʻahaʻa haʻahaʻa, kahi paila kiʻekiʻe, a me ka polarity kiʻekiʻe non proton solvent a me ka intermediate chemical, hoʻohana nui ʻia i nā kula e like me nā mea synthetic, pharmaceuticals, pesticides, chemical fibers, petroleum processing, and organic pigments.
He aha nā hoʻohana nui o ka dimethyl formamide?
01hoʻohana ʻia ma ke ʻano he analytical reagent 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 ka mea maka no nā extractants, pharmaceuticals, a me nā pesticides e like me imidacloprid.
03ʻAʻole ʻo Dimethylformamide wale nō kahi mea hoʻohana kemika i hoʻohana nui ʻia, akā he mea hoʻoheheʻe maikaʻi loa me ka nui o ka hoʻohana ʻana.ʻO ka dimethylformamide he mea hoʻoheheʻe maikaʻi no nā polymers kiʻekiʻe e like me ka polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, a me nā mea'ē aʻe.Hoʻohana ʻia no ka hana kiʻiʻoniʻoni plastik;Hiki ke hoʻohana ʻia e like me ka wehe ʻana i ka pena no ka wehe ʻana i ka pena;Hiki iā ia ke hoʻoheheʻe i kekahi mau puaʻa haʻahaʻa haʻahaʻa, hāʻawi iā lākou i nā ʻano o nā kala.Hoʻohana ʻia ʻo Dimethylformamide no ka unuhi ʻana i ka hydrocarbon aromatic, a me ka hoʻokaʻawale ʻana a me ka hoʻihoʻi hou ʻana i ka butadiene mai ka hakina C4 a me ka isoprene mai ka hakina C5.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 isophthalic acid a me ka terephthalic acid: ʻoi aku ka nui o ka solubility o ka isophthalic acid i ka dimethylformamide ma mua o ka terephthalic acid.Hiki ke hoʻokaʻawale i nā mea ʻelua i ka hoʻokaʻawale ʻana a i ʻole ka crystallization ʻāpana i ka dimethylformamide.I ka ʻoihana petrochemical, hiki ke hoʻohana ʻia ka dimethyl formamide ma ke ʻano he mea hoʻoheheʻe kinoea no ka hoʻokaʻawale ʻana a me ka hoʻomaʻemaʻe ʻana i nā kinoea.I loko o nā hopena kūlohelohe, ʻaʻole hoʻohana nui ʻia ka dimethylformamide ma ke ʻano he solvent, akā he mea koʻikoʻi hoʻi i ka synthesis organik.Hiki ke hoʻohana ʻia e hana i nā chlorpyrifos i ka ʻoihana pesticide;I ka ʻoihana lāʻau lapaʻau, hiki ke hoʻohana ʻia e synthesize i ka pyrimidine iodide, doxycycline, cortisone, vitamin B6, iodoside, Qubijing, thiapyrimidine, N-formyl sarcolysin, antineoplastic acid, methoxyaromaine, bianzapine, cyclohexanone nitrourea, Femetrostatic acid, methoxyaromaine. , biliveratrol, chlorpheniramine, a pēlā aku.Hoʻokani ʻo Dimethylformamide i ka hana catalytic i ka hydrogenation, dehydrogenation, dehydration, a me nā hopena dehalogenation, e hōʻemi ana i ka mahana hopena a me ka hoʻomaikaʻi ʻana i ka maʻemaʻe o ka huahana.
04Non aqueous solution titration reagent, solvent no ka ethylene resin a me ka acetylene, organic synthesis, photometry, gas chromatography stationary phase (ke kiʻekiʻe o ka hana wela 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 trans butene .Ka nānā ʻana i ke koena pesticide.ʻO ka hoʻohuihui ʻana.ʻO ka hui ʻana o ka peptide.Hoʻohana ʻia i ka ʻoihana kiʻi.
