Ukusetshenziswa:I-Dimethylamide (DMF) iyi-chemical material eluhlaza kanye ne-solvent esebenza kahle kakhulu, esetshenziswa kakhulu ezimbonini ezifana ne-polyurethane, i-acrylic, imithi, izibulala-zinambuzane, odayi, izinto zikagesi, njll. Njenge-ejenti yokugeza nokwelapha embonini ye-polyurethane, ikakhulukazi esetshenziselwa ukukhiqizwa kwesikhumba esimanzi sokwenziwa;Njengesidakamizwa sokwenziwa esimaphakathi embonini yezemithi, sisetshenziswa kabanzi ekukhiqizeni izidakamizwa ze-doxycycline, i-cortisone, ne-sulfonamide;Njenge-solvent embonini ye-acrylic fibre, isetshenziselwa ikakhulukazi ukukhiqizwa kokuphotha okomile kwamafayili e-acrylic;Isetshenziswa embonini yezibulala-zinambuzane ukuze kuhlanganiswe izibulala-zinambuzane ezisebenzayo nezinobuthi obuphansi;Isetshenziswa njenge-solvent edayi embonini yodayi;Ukucinywa kwezingxenye zikathayela nokuhlanzwa kwamabhodi esekethe embonini yezogesi;Ezinye izimboni zihlanganisa abathwali bamagesi ayingozi, izinyibilikisi ze-crystallization yezidakamizwa, izinto zokunamathisela, njll.

Igama lekhemikhali: N, N-dimethylacetamide

I-Dimethylacetamide iyi-solvent eqinile ye-polar engeyona i-protonated engancibilikisa inhlanganisela ehlukahlukene futhi ixubene ngokuphelele namanzi, ama-ether, ama-ketone, ama-esters, njll. Inokuqina okuphezulu kokushisa, ukumelana ne-hydrolysis ephansi, ukugqwala okuphansi, nobuthi obuphansi.Inoncibilika kahle kuma-resin ahlukahlukene, ikakhulukazi i-polyurethane resin kanye ne-polyimide resin, futhi ingasetshenziswa njengesixazululi semicu yokwenziwa engashisi ukushisa, amafilimu epulasitiki, okokumboza, kwezemithi, nokuphotha kwe-acrylonitrile.I-Dimethylacetamide, njengobuthi obuphansi, indawo ebilayo ephezulu, kanye ne-polarity ephezulu engeyona i-proton solvent kanye namakhemikhali aphakathi nendawo, isetshenziswa kabanzi emikhakheni efana nezinto zokwenziwa, imithi, izibulala-zinambuzane, imicu yamakhemikhali, ukucutshungulwa kwe-petroleum, kanye ne-organic pigments.

Yiziphi ukusetshenziswa okuyinhloko kwe-dimethyl formamide?

01isetshenziswa njenge-reagent yokuhlaziya kanye ne-solvent ye-ethylene resin ne-acetylene

02iyi-solvent enhle kakhulu ye-organic esetshenziswa njenge-solvent ye-polyurethane, i-polyacrylonitrile, ne-polyvinyl chloride, kanye nempahla eluhlaza yokukhishwa, imithi, kanye nezibulala-zinambuzane ezifana ne-imidacloprid.

03I-Dimethylformamide ayiyona nje into eluhlaza yamakhemikhali esetshenziswa kabanzi, kodwa futhi iyincibilikisi enhle kakhulu enezinhlobonhlobo zokusetshenziswa.I-Dimethylformamide iyi-solvent enhle yama-polymers aphakeme ahlukahlukene njenge-polyethylene, i-polyvinyl chloride, i-polyacrylonitrile, i-polyamide, njll. Ingasetshenziselwa ukuphotha okumanzi kwemicu yokwenziwa efana ne-polyacrylonitrile fibers kanye nokuhlanganiswa kwe-polyurethane;Isetshenziselwa ukwenza ifilimu yepulasitiki;Ingasetshenziswa futhi njengesikhiphi sikapende sokususa upende;Ingaphinda incibilikise izingulube ezithile ezincibilikayo eziphansi, ibanike izici zodayi.I-Dimethylformamide isetshenziselwa ukukhishwa kwe-hydrocarbon enamakha, kanye nokuhlukanisa nokubuyisela i-butadiene kusuka kungxenyana ye-C4 kanye ne-isoprene kusuka kungxenyana ye-C5.Ingasetshenziswa futhi njenge-reagent ephumelelayo yokuhlukanisa izingxenye ezingezona i-hydrocarbon kupharafini.Inokukhethwa okuhle kokuncibilika kwe-isophthalic acid ne-terephthalic acid: ukuncibilika kwe-isophthalic acid ku-dimethylformamide kukhulu kunaleyo e-terephthalic acid.Ukukhishwa kwe-solvent noma i-crystallization eyingxenye ku-dimethylformamide kungahlukanisa kokubili.Embonini ye-petrochemical, i-dimethyl formamide ingasetshenziswa njengesithako segesi sokuhlukanisa nokucwengisisa amagesi.Ekuphenduleni kwezinto eziphilayo, i-dimethylformamide ayisetshenziswa nje kuphela njenge-solvent, kodwa futhi iyingxenye ebalulekile ekuhlanganiseni kwe-organic.Ingasetshenziselwa ukukhiqiza i-chlorpyrifos embonini yezibulala-zinambuzane;Embonini yezemithi, ingasetshenziswa ukwenza 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 i-furourane, i-progesterone, i-nitrourea, i-progesteroni, , i-biliveratrol, i-chlorpheniramine, njalonjalo.I-Dimethylformamide idlala indima ebalulekile ku-hydrogenation, dehydrogenation, dehydration, kanye nokusabela kwe-dehalogenation, ukunciphisa izinga lokushisa lokuphendula kanye nokwenza ngcono ukuhlanzeka komkhiqizo.

04I-Reagent ye-non-aqueous solution titration reagent, i-solvent ye-ethylene resin ne-acetylene, i-organic synthesis, i-photometry, isigaba segesi se-chromatography (izinga lokushisa eliphezulu lokusebenza 50 ℃, i-solvent methanol), ukuhlukaniswa nokuhlaziywa kwe-C2-C5 hydrocarbons, kanye nekhono lokuhlukanisa evamile, isobutene. , cis, kanye ne-trans butene .Ukuhlaziywa kwezinsalela zezibulala-zinambuzane.I-Organic synthesis.I-Peptide synthesis.Isetshenziswa embonini yezithombe.
