ʻO ka wai aniani ʻaʻohe waihoʻoluʻu a i ʻole ka wai melemele māmā me ka ʻala iʻa

1. He mea hoʻoheheʻe organik maikaʻi loa ia, i hoʻohana ʻia e like me ka solvent no ka polyurethane, polyacrylonitrile, a me ka polyvinyl chloride.Hoʻohana ʻia ia ma ke ʻano he mea maka no nā extractants, 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 ʻo Dimethylformamide wale nō kahi mea hoʻoheheʻe kemika maikaʻi loa, akā he mea hoʻoheheʻe maikaʻi loa.ʻO ka dimethylformamide he mea hoʻoheheʻe maikaʻi no nāʻano polymers e like me ka polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, a me nā mea'ē aʻe, a hiki ke hoʻohanaʻia no ka wili pulu o nā fibers synthetic e like me ka polyacrylonitrile fiber, a me ka synthesis o polyurethane;Hoʻohana ʻia i ka hana kiʻiʻoniʻoni plastik;hiki ke hoʻohana ʻia e like me ka wehe ʻana i ka pena e wehe i ka pena;hiki iā ia ke hoʻoheheʻe i kekahi mau puaʻa haʻahaʻa haʻahaʻa, e hāʻawi ana i nā puaʻa i nā ʻano o nā kala.Hoʻohana ʻia ʻo Dimethylformamide no ka unuhi ʻana a me ka hoʻokaʻawale ʻana o 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 ke koho maikaʻi i 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 i ka Chemicalbook ke hoʻokaʻawale i nā mea ʻelua.I ka ʻoihana petrochemical, hiki ke hoʻohana ʻia ka dimethylformamide ma ke ʻano he mea e hoʻokaʻawale a hoʻomaʻemaʻe i ke kinoea.I loko o nā hopena kūlohelohe, ʻaʻole hoʻohana nui ʻia ka dimethylformamide 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 nā insecticide;i ka ʻoihana lāʻau lapaʻau, hiki ke hoʻohana ʻia e synthesize iodosamine, doxycycline, cortisone, vitamin B6, iodoside, ququjing, pyrantel, N-formyllysar Onumaric acid, methoxy mustard, chlorambucil, nitrosourea, furfurouracil, tranexamic acid, metgestrolmethasone. chlorpheniramine, etc. He hopena catalytic ka Dimethylformamide i nā hopena o ka hydrogenation, dehydrogenation, dehydration a me ka dehydrohalogenation, e hoʻemi ana i ka mahana hopena a hoʻomaikaʻi i ka maʻemaʻe o ka huahana.

4.Titration o nā mea hoʻoheheʻe wai ʻole.Mea hoʻoheheʻe no ka resin vinyl a me ka acetylene.Hoʻoholo kiʻi kiʻi.ʻO ke kinoea chromatographic stationary wai (ʻoi loa ka hoʻohana ʻana i ka mahana he 50 ℃, ka mea hoʻoheheʻe he methanol), hoʻokaʻawale ʻo Chemicalbook no ka nānā ʻana i nā hydrocarbons C2-C5, a hiki ke hoʻokaʻawale i ka maʻamau a me ka isobutene a me ka cis a me ka trans-2-butene.Ka nānā 'ana i nā koena pesticide.Hoʻohui ʻia.ʻO ka hui ʻana o nā peptides.No ka ʻoihana kiʻi.
