Amathegi Omkhiqizo

Ukusetshenziswa:I-Dimethylamide (DMF) iyi-chemical proper solvent ebalulekile kanye ne-solvent esebenza kahle, esetshenziswa kakhulu ezimbonini ezifana ne-polyurethane, i-acrylic, imithi, izibulala-zinambuzane, amadayi, izinto zikagesi, njll. Njenge-ejenti yokuwasha nokupholisa embonini ye-polyurethane, isetshenziswa kakhulu ekukhiqizweni kwesikhumba esimanzi esenziwe; Njengesidakamizwa sokwenziwa esiphakathi embonini yemithi, isetshenziswa kabanzi ekukhiqizweni kwemithi ye-doxycycline, i-cortisone, kanye ne-sulfonamide; Njenge-solvent embonini ye-acrylic fiber, isetshenziswa kakhulu ekukhiqizweni kwe-dry spinning ye-acrylic fiber; Isetshenziswa embonini yezinambuzane ukukhiqiza izibulala-zinambuzane ezisebenzayo nezinobuthi obuphansi; Isetshenziswa njenge-solvent yodayi embonini yedayi; Ukucima izingxenye ezifakwe ethini kanye nokuhlanza amabhodi wesekethe embonini ye-elekthronikhi; Ezinye izimboni zifaka abathwali bamagesi ayingozi, izinyibilikisi zokwakheka kwezidakamizwa, izinamathiseli, njll.

Igama lamakhemikhali: N, N-dimethylacetamide

I-Dimethylacetamide iyi-solvent enamandla ye-polar non-protonated engancibilikisa ama-compound ahlukahlukene futhi ixutshwe ngokuphelele namanzi, ama-ether, ama-ketone, ama-ester, njll. Inokuzinza okuphezulu kokushisa, ukumelana okuphansi kwe-hydrolysis, ukugqwala okuphansi, kanye nobuthi obuphansi. Inokuncibilika okuhle kwama-resin ahlukahlukene, ikakhulukazi i-polyurethane resin kanye ne-polyimide resin, futhi ingasetshenziswa njenge-solvent yama-fibre synthetic amelana nokushisa, amafilimu epulasitiki, izembozo, imithi, kanye ne-acrylonitrile spinning. I-Dimethylacetamide, njenge-toxicity ephansi, iphuzu lokubila eliphezulu, kanye ne-polarity ephezulu ye-non-proton solvent kanye ne-chemical intermediate, isetshenziswa kabanzi emikhakheni efana nezinto zokwenziwa, imithi, izibulala-zinambuzane, imicu yamakhemikhali, ukucubungula i-petroleum, kanye nemibala ephilayo.

Yiziphi izindlela eziyinhloko zokusebenzisa i-dimethyl formamide?

01isetshenziswa njenge-reagent yokuhlaziya kanye nesinyibilikisi se-ethylene resin kanye ne-acetylene

02iyi-solvent enhle kakhulu esetshenziswa njenge-solvent ye-polyurethane, i-polyacrylonitrile, ne-polyvinyl chloride, kanye nezinto zokusetshenziswa ezikhipha izinto, imithi, kanye nezibulala-zinambuzane ezifana ne-imidacloprid

03I-Dimethylformamide ayiyona nje into eluhlaza esetshenziswa kakhulu ngamakhemikhali, kodwa futhi iyisithako esihle kakhulu esinokusetshenziswa okubanzi. I-Dimethylformamide iyisithako esihle sama-polymer ahlukahlukene aphezulu njenge-polyethylene, i-polyvinyl chloride, i-polyacrylonitrile, i-polyamide, njll. Ingasetshenziswa ekuphotheni okumanzi kwemicu yokwenziwa njengemicu ye-polyacrylonitrile kanye nokuhlanganiswa kwe-polyurethane; Isetshenziselwa ukwenza ifilimu yepulasitiki; Ingasetshenziswa futhi njengesisusi sopende sokususa upende; Ingaphinde incibilikise ama-pigment athile ancibilikayo aphansi, iwanike izici zamadayi. I-Dimethylformamide isetshenziselwa ukukhipha i-aromatic hydrocarbon, kanye nokuhlukanisa nokubuyisa i-butadiene engxenyeni ye-C4 kanye ne-isoprene engxenyeni ye-C5. Ingasetshenziswa futhi njenge-reagent ephumelelayo yokuhlukanisa izingxenye ezingezona i-hydrocarbon ku-paraffin. Inokukhetha okuhle kokuncibilika kwe-isophthalic acid kanye ne-terephthalic acid: ukuncibilika kwe-isophthalic acid ku-dimethylformamide kukhulu kunalokho okuku-terephthalic acid. Ukukhishwa kwe-solvent noma ukwakheka kwekristalu okuyingxenye ku-dimethylformamide kungahlukanisa lokhu kokubili. Embonini ye-petrochemical, i-dimethyl formamide ingasetshenziswa njengento emunca igesi yokuhlukanisa nokucwenga amagesi. Ekuphenduleni kwezinto eziphilayo, i-dimethylformamide ayisetshenziswa kabanzi nje kuphela njengesinyibilikisi, kodwa futhi iyindawo ebalulekile ekuhlanganisweni kwezinto eziphilayo. Ingasetshenziswa ukukhiqiza i-chlorpyrifos embonini yezibulala-zinambuzane; Embonini yemithi, ingasetshenziswa ukuhlanganisa i-pyrimidine iodide, i-doxycycline, i-cortisone, i-vitamin B6, i-iodoside, i-Qubijing, i-thiapyrimidine, i-N-formyl sarcolysin, i-antineoplastic acid, i-methoxyaromaine, i-bianzapine, i-cyclohexanone nitrourea, i-furfouroacil, i-hemostatic acid, i-Fenfenmethasone, i-medroxyprogesterone, i-biliveratrol, i-chlorpheniramine, njalo njalo. I-Dimethylformamide idlala indima yokuvuselela ekuhlanganiseni i-hydrogenation, ekuhlukaniseni i-hydrogenation, ekuphelelweni kwamanzi emzimbeni, nasekususweni kwe-halogenation, ukunciphisa izinga lokushisa lokusabela nokuthuthukisa ubumsulwa bomkhiqizo.

04I-reagent ye-titration yesisombululo esingemanzi, i-solvent ye-ethylene resin ne-acetylene, ukwakheka kwezinto eziphilayo, i-photometry, isigaba esimile se-gas chromatography (izinga lokushisa eliphezulu lokusebenza elingu-50 ℃, i-solvent methanol), ukuhlukaniswa nokuhlaziywa kwama-hydrocarbon e-C2-C5, kanye nekhono lokuhlukanisa i-normal, i-isobutene, i-cis, ne-trans butene. Ukuhlaziywa kwezinsalela zezibulala-zinambuzane. Ukwakheka kwezinto eziphilayo. Ukwakheka kwe-peptide. Kusetshenziswa embonini yezithombe.
