Zita remakemikari: N, N-dimethylacetamide
Dimethylacetamide chinhu chakasimba chine polar non protonated solvent chinogona kunyungudutsa makemikari akasiyana-siyana uye chinogona kusanganiswa nemvura, ethers, ketones, esters, nezvimwewo. Chine kugadzikana kwakanyanya kwekupisa, chinodzivirira hydrolysis shoma, ngura shoma, uye chepfu shoma. Chine kunyunguduka kwakanaka kwemaresini akasiyana-siyana, kunyanya polyurethane resin ne polyimide resin, uye chinogona kushandiswa se solvent ye fibers dze synthetic dzinodzivirira kupisa, mafirimu epurasitiki, ma coatings, pharmaceuticals, uye acrylonitrile spinning. Dimethylacetamide, se low toxicity, high boiling point, uye high polarity non proton solvent uye chemical intermediate, chinoshandiswa zvakanyanya muminda yakaita sezvinhu zvekugadzira, pharmaceuticals, pesticides, chemical fibers, petroleum processing, uye organic pigments.
Ndezvipi zvinonyanya kushandiswa ne dimethyl formamide?
01inoshandiswa semushonga wekuongorora uye solvent ye ethylene resin uye acetylene
02chinhu chakanaka kwazvo chinoshandiswa se organic solvent ye polyurethane, polyacrylonitrile, uye polyvinyl chloride, pamwe chete nekugadzira zvinhu zvinoburitsa, mishonga, uye mishonga yezvipembenene yakaita se imidacloprid.
03Dimethylformamide haisi chinhu chinoshandiswa zvakanyanya chete nemakemikari, asiwo chinhu chinonyungudutsa chakanaka chine mashandisirwo akasiyana-siyana. Dimethylformamide chinhu chinonyungudutsa chakanaka chepolymers dzakasiyana-siyana dzakadai sepolyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, nezvimwewo. Inogona kushandiswa pakunyorova mafiber ekugadzira akadai sepolyacrylonitrile fibers uye kugadzira polyurethane; Inoshandiswa pakugadzira purasitiki; Inogona zvakare kushandiswa semushonga wekubvisa pendi; Inogona zvakare kunyungudutsa mamwe mavara asina kunyunguduka, zvichivapa hunhu hwedhayi. Dimethylformamide inoshandiswa pakuburitsa aromatic hydrocarbon, pamwe nekuparadzanisa nekudzorera butadiene kubva kuchikamu cheC4 uye isoprene kubva kuchikamu cheC5. Inogona zvakare kushandiswa semushonga unoshanda wekuparadzanisa zvinhu zvisiri zvehydrocarbon kubva kuparaffin. Ine sarudzo yakanaka yekunyungudutsa kweisophthalic acid neterephthalic acid: kunyunguduka kweisophthalic acid mudimethylformamide kwakakura kupfuura kuri muterephthalic acid. Kubvisa zvinonyungudutsa kana kupatsanura chikamu chekristall mu dimethylformamide kunogona kuparadzanisa zviviri izvi. Muindasitiri ye petrochemical, dimethyl formamide inogona kushandiswa sechinhu chinonyungudutsa gasi pakuparadzanisa nekunatsa magasi. Mukuita kwe organic, dimethylformamide haingoshandiswi zvakanyanya se solvent, asiwo chinhu chakakosha mukugadzirwa kwe organic. Inogona kushandiswa kugadzira chlorpyrifos muindasitiri yemishonga yezvipembenene; Muindasitiri yemishonga, inogona kushandiswa kugadzira pyrimidine iodide, doxycycline, cortisone, vitamin B6, iodoside, Qubijing, thiapyrimidine, N-formyl sarcolysin, antineoplastic acid, methoxyaromaine, bianzapine, cyclohexanone nitrourea, furfouracil, hemostatic acid, Fenfenmethasone, medroxyprogesterone, biliveratrol, chlorpheniramine, nezvimwewo. Dimethylformamide inoita basa re catalytic mu hydrogenation, dehydrogenation, dehydration, uye dehalogenation reactions, kuderedza tembiricha ye reaction uye kuvandudza kuchena kwechigadzirwa.
04Mhinduro isina mvura inonzi titration reagent, solvent ye ethylene resin ne acetylene, organic synthesis, photometry, gas chromatography stationary phase (high operating tembiricha 50 ℃, solvent methanol), kupatsanurwa uye kuongororwa kwe C2-C5 hydrocarbons, uye kugona kupatsanura normal, isobutene, cis, uye trans butene. Kuongororwa kwepesticide residue. Organic synthesis. Peptide synthesis. Inoshandiswa muindasitiri yekutora mifananidzo.
