N,N-Dimethylacetamide (DMAc) CAS 127-19-5 Maʻemaʻe ≥99.80% (GC) Hale Hana

ʻO N,N-Dimethylacetamide (DMAc) (CAS: 127-19-5) he mea hoʻoheheʻe polar aprotic kiʻekiʻe, micro ammonia ʻala, mana hoʻoheheʻe ikaika loa, hiki ke hoʻoheheʻe ʻia, hiki ke hoʻoheheʻe ʻia me ka wai, nā mea ʻala, nā esters, ketones, alcohols, etera, benzene a me ka chloroform a me nā mea ʻē aʻe a hiki i ka hoʻoulu ʻana o nā pūhui molekala.Hoʻohana nui ʻia ia e like me ka solvent a me ka catalyst.ʻO ka mea hoʻoheheʻe, me kahi kiʻekiʻe e hoʻolapalapa ai, ke kiko uila, ke kūpaʻa wela a me ke kūpaʻa kemika o ka mea hoʻoheheʻe, hoʻohana ʻia no ka polyacrylonitrile spinning solvent, synthetic resin a me nā resins maoli, formic acid vinyl ester resin, vinyl pyridine copolymer and aromatic carboxylic acid.Hiki ke hoʻohana ʻia ka catalyst i ke kaʻina hana o ka hoʻomehana ʻana e hana i ka hopena o ka cyanide, sodium halide a me metala cyanide e hana i ka hopena o ka alkyl acetylene, organic halide a me isocyanate.Hiki ke hoʻohana ʻia ʻo N, N-Dimethylacetamide ma ke ʻano he electrolytic solvent a me ke kiʻi me ka solvent coupler, de paint agent, organic synthesis of raw material, pesticide a me nā lāʻau lapaʻau.ʻO ka hoʻokaʻawale ʻana o ka styrene mai ka hakina C8, unuhi, distillation, solvent, etc.
Hoʻohana ʻia ʻo N, N-Dimethylacetamide ma ke ʻano he polar solvent i ka synthesis organik a me nā hopena e pili ana i nā kumu ikaika e like me ka sodium hydroxide.Hoʻohana ʻia ia e like me ka solvent no nā fibers e like me polyacrylonitrile, spandex, ma ke ʻano he excipient i nā lāʻau lapaʻau.vumon, busulfex a ma ka ʻoihana hoʻopili.Loaʻa iā ia ka noi ma ke ʻano he ʻano hopena i ka hana ʻana i nā lāʻau lapaʻau, agrochemical, dyes a me nā plasticizers.Hoʻohana nui ʻia ia i ka ʻoihana polymer ma muli o kona mana hoʻonā kiʻekiʻe no nā polymers molecular-weight kiʻekiʻe a me nā resins synthetic.He kuleana koʻikoʻi ia ma ke ʻano he catalyst ma nā ʻano hopena like ʻole.cyclization, halogenation, cynidation, alkylation and dehydrogenation a hoʻonui i ka hua o nā huahana nui.Hoʻohana ʻia ʻo ia ma ke ʻano he mea unuhi no ka aila a me nā kinoea, i ka wehe ʻana i ka pena, i ka hana ʻana i nā pūhui hoʻoneʻe paʻi kiʻi a me ka mea hoʻoheheʻe booster i nā uhi.
ʻO DMAc kahi mea hoʻoheheʻe synthetic i hana ʻia mai ka hopena o ka dimethylamine a me ka acetic acid a i ʻole acetic anhydride.Hoʻopili pinepine ʻia ʻo DMAc me nā hoʻohana ʻoihana he nui, ma ke ʻano he mea hoʻomaka a i ʻole he waena.ʻO DMAc kahi mea hoʻoheheʻe maikaʻi i hoʻohana ʻia i ka polymer dissolution, ʻoi aku hoʻi i ka ʻoihana fiber.
ʻO N, N-Dimethylacetamide kahi mea hoʻoheheʻe maikaʻi loa a hana pinepine ma ke ʻano he catalyst i ka halogenation, cyclization, a me nā hopena alkylation.He mea hoʻoheheʻe ʻoihana koʻikoʻi no ka polyacrylonitrile, vinyl resins, cellulose derivatives, styrene polymers a me linear polyesters.Hoʻohana ʻia ia i loko o nā keʻena hana analytical a pau ma ke ʻano he mea nui o ka pae kelepona i High Performance Liquid Chromatography (HPLC) a me Liquid Chromatography - Mass Spectrometry (LC-MS).N, N-dimethylacetamide lithium chelate complexes intercalate cationic sites in layered silicates.
Hoʻohana nui ʻia ʻo N, N-Dimethylacetamide ma ke ʻano he mea hoʻoheheʻe ʻenehana a waena i ka hana ʻana i nā lāʻau lapaʻau, nā kemika maikaʻi, nā agrochemical, polymers, a me nā resins.Hoʻohana ʻia ʻo ia ma ke ʻano he mea hoʻoheheʻe wili i ka hana ʻana o nā fibers o nā polymers like ʻole, me ka acrylic, polyurethane, polyurea copolymer, a me ka meta-aramid.Eia kekahi, hoʻohana pū ʻia kēia solvent aprotic dipolar i nā X-ray a me nā huahana kiʻi a me ka hana ʻana i nā kiʻiʻoniʻoni polyimide.
