Lebitso la lik'hemik'hale: N, N-dimethylacetamide
Dimethylacetamide ke solvent e matla e sa etseng proton e ka qhalang metsoako e fapaneng mme e kopanngwa ka botlalo le metsi, di-ether, di-ketone, di-ester, jj. E na le botsitso bo phahameng ba mocheso, khanyetso e tlase ya hydrolysis, tshenyo e tlase, le chefo e tlase. E na le ho qhibiliha ho hotle bakeng sa di-resin tse fapaneng, haholo-holo resin ya polyurethane le resin ya polyimide, mme e ka sebediswa e le solvent bakeng sa difaeba tsa maiketsetso tse hanelang mocheso, difilimi tsa polasetiki, dikobo, meriana le ho potoloha ha acrylonitrile. Dimethylacetamide, e le tjhefo e tlase, ntlha e phahameng ya ho belisa, le polarity e phahameng non proton solvent le chemical intermediate, e sebediswa haholo masimong a kang thepa ya maiketsetso, meriana, dibolayadikokwanyana, difaeba tsa dikhemikhale, ts'ebetso ya peterole le di-pigment tsa organic.
Tšebeliso e ka sehloohong ea dimethyl formamide ke efe?
01e sebelisoa e le sesebelisoa sa ho sekaseka le ho qhibilihisa bakeng sa resin ea ethylene le acetylene
02ke tharollo e ntle ka ho fetisisa ea lintho tse phelang e sebelisoang e le tharollo ea polyurethane, polyacrylonitrile, le polyvinyl chloride, hammoho le thepa e tala bakeng sa li-extractants, meriana le chefo e bolaeang likokoanyana tse kang imidacloprid
03Dimethylformamide ha se feela thepa e tala e sebelisoang haholo ea lik'hemik'hale, empa hape ke tharollo e ntle haholo e nang le mefuta e mengata ea ts'ebeliso. Dimethylformamide ke tharollo e ntle bakeng sa li-polymer tse fapaneng tse phahameng joalo ka polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, jj. E ka sebelisoa bakeng sa ho phutholla ka metsi likhoele tsa maiketsetso joalo ka likhoele tsa polyacrylonitrile le ho kopanya polyurethane; E sebelisoa bakeng sa ho etsa filimi ea polasetiki; E ka boela ea sebelisoa e le sesebelisoa sa ho tlosa pente bakeng sa ho tlosa pente; E ka boela ea qhala mebala e itseng e qhibilihang ka tlase, e ba fang litšobotsi tsa dae. Dimethylformamide e sebelisoa bakeng sa ho ntša hydrocarbon e nkhang hamonate, hammoho le ho arola le ho khutlisa butadiene ho tsoa karolong ea C4 le isoprene ho tsoa karolong ea C5. E ka boela ea sebelisoa e le sesebelisoa se sebetsang sa ho arola likarolo tse seng tsa hydrocarbon ho tloha paraffin. E na le khetho e ntle bakeng sa ho qhibiliha ha isophthalic acid le terephthalic acid: ho qhibiliha ha isophthalic acid ho dimethylformamide ho feta ho feta ho terephthalic acid. Ho ntšoa ha solvent kapa ho kristalella karoloana ho dimethylformamide ho ka arola tse peli. Indastering ea petrochemical, dimethyl formamide e ka sebelisoa e le monya khase bakeng sa ho arola le ho hloekisa likhase. Likarabelong tsa lintho tse phelang, dimethylformamide ha e sebelisoe feela e le solvent, empa hape ke karolo ea bohlokoa ea motsoako oa lintho tse phelang. E ka sebelisoa ho hlahisa chlorpyrifos indastering ea chefo e bolaeang likokoanyana; Indastering ea meriana, e ka sebelisoa ho kopanya pyrimidine iodide, doxycycline, cortisone, vithamine B6, iodoside, Qubijing, thiapyrimidine, N-formyl sarcolysin, antineoplastic acid, methoxyaromaine, bianzapine, cyclohexanone nitrourea, furfouroacil, hemostatic acid, Fenfenmethasone, medroxyprogesterone, biliveratrol, chlorpheniramine, jj. Dimethylformamide e bapala karolo ea catalytic ho hydrogenation, dehydrogenation, dehydration, le dehalogenation reactions, ho fokotsa mocheso oa karabelo le ho ntlafatsa bohloeki ba sehlahisoa.
04Tharollo e seng metsi e etsang hore reagent ea titration e se ke ea e-ba metsi, e leng solvent bakeng sa resin ea ethylene le acetylene, synthesis ea organic, photometry, gas chromatography stationary phase (mocheso o phahameng oa ts'ebetso oa 50 ℃, solvent methanol), karohano le tlhahlobo ea li-hydrocarbon tsa C2-C5, le bokhoni ba ho arola normal, isobutene, cis, le trans butene. Tlhahlobo ea masala a chefo e bolaeang likokoanyana. Synthesis ea organic. Synthesis ea peptide. E sebelisoa indastering ea ho nka lifoto.
