Aha kemịkalụ: N, N-dimethylacetamide
Dimethylacetamide bụ ihe mgbaze siri ike nke na-abụghị protonated nke nwere ike ịgbaze ọtụtụ ihe dị iche iche ma na-agwakọta ya kpamkpam na mmiri, ethers, ketone, esters, wdg. Ọ nwere nnukwu nkwụsi ike okpomọkụ, obere iguzogide hydrolysis, obere nchara, na obere nsí. Ọ nwere ezigbo mgbaze maka ọtụtụ resins, ọkachasị polyurethane resin na polyimide resin, enwere ike iji ya dị ka ihe mgbaze maka eriri sịntetik na-eguzogide okpomọkụ, ihe nkiri plastik, mkpuchi, ọgwụ, na acrylonitrile spinning. Dimethylacetamide, dị ka obere nsí, ebe a na-esi mmiri nke ọma, na nnukwu polarity non proton solvent na chemical intermediate, bụ nke a na-ejikarị eme ihe n'ọhịa dịka ihe sịntetik, ọgwụ, ọgwụ nje, eriri kemịkalụ, nhazi mmanụ ala, na agba organic.
Kedu ihe bụ isi eji dimethyl formamide eme ihe?
01eji ya dị ka ihe nyocha na ihe mgbaze maka ethylene resin na acetylene
02bụ ihe mgbaze organic magburu onwe ya nke a na-eji dị ka ihe mgbaze maka polyurethane, polyacrylonitrile, na polyvinyl chloride, yana ihe eji emepụta ihe, ọgwụ, na ọgwụ nje dịka imidacloprid
03Dimethylformamide abụghị naanị ihe eji emepụta kemịkalụ nke a na-ejikarị eme ihe, kamakwa ọ bụ ihe mgbaze dị mma nke nwere ọtụtụ ojiji. Dimethylformamide bụ ezigbo ihe mgbaze maka ọtụtụ polymer dị elu dịka polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, wdg. Enwere ike iji ya maka ịgbagharị mmiri nke eriri sịntetik dịka eriri polyacrylonitrile na njikọta nke polyurethane; A na-eji ya eme ihe nkiri plastik; A pụkwara iji ya dị ka ihe na-ewepụ agba maka iwepụ agba; Ọ nwekwara ike ịgbaze ụfọdụ agba ndị na-agbaze obere, na-enye ha njirimara nke agba. A na-eji Dimethylformamide eme ihe maka mwepụta hydrocarbon aromatic, yana maka ikewapụ na iweghachite butadiene na C4 fraction na isoprene na C5 fraction. A pụkwara iji ya dị ka ihe na-arụ ọrụ dị irè maka ikewapụ ihe ndị na-abụghị hydrocarbon na paraffin. Ọ nwere ezigbo nhọrọ maka ịgbaze nke isophthalic acid na terephthalic acid: ịgbaze nke isophthalic acid na dimethylformamide karịrị nke dị na terephthalic acid. Mwepụta ihe mgbaze ma ọ bụ kristal akụkụ na dimethylformamide nwere ike kewaa ha abụọ. N'ụlọ ọrụ petrochemical, enwere ike iji dimethyl formamide dị ka ihe na-amịkọrọ gas maka ikewapụ na imezi gas. Na mmeghachi omume organic, a naghị eji dimethylformamide eme ihe dị ka ihe mgbaze, kamakwa ọ bụ ihe dị mkpa na njikọta organic. Enwere ike iji ya mepụta chlorpyrifos na ụlọ ọrụ ọgwụ ahụhụ; N'ụlọ ọrụ ọgwụ, enwere ike iji ya mepụta pyrimidine iodide, doxycycline, cortisone, vitamin B6, iodoside, Qubijing, thiapyrimidine, N-formyl sarcolysin, antineoplastic acid, methoxyaromaine, bianzapine, cyclohexanone nitrourea, furfurouracil, hemostatic acid, Fenfenmethasone, medroxyprogesterone, biliveratrol, chlorpheniramine, na ndị ọzọ. Dimethylformamide na-arụ ọrụ dị mkpa na hydrogenation, dehydrogenation, dehydrogenation, na dehalogenation mmeghachi omume, na-ebelata okpomọkụ mmeghachi omume ma na-eme ka ịdị ọcha ngwaahịa dịkwuo mma.
04Ihe na-eme ka mmiri ghara ịcha mmiri, ihe mgbaze maka ethylene resin na acetylene, njikọ organic, photometry, usoro chromatography gas stainless phase (oke okpomọkụ ọrụ kachasị 50 ℃, methanol solvent), nkewa na nyocha nke hydrocarbons C2-C5, na ikike nkewa nke nkịtị, isobutene, cis, na trans butene. Nyocha ihe fọdụrụ nke ọgwụ nje. Nhazi organic. Nhazi peptide. Ejiri ya na ụlọ ọrụ foto.
