Tohu Hua

Whakamahinga:Ko te Dimethylamide (DMF) he rauemi matū nui me te whakarewa mahi nui, e whakamahia ana i roto i nga ahumahi penei i te polyurethane, acrylic, pharmaceuticals, pesticides, waikano, hikohiko, me etahi atu. whakamahia i roto i te hanga o te hiako waihanga maku;Hei takawaenga rongoa rongoa i roto i te umanga rongoa, ka whakamahia nuitia ki te hanga doxycycline, cortisone, me nga raau taero sulfonamide;Ka rite ki te whakarewa i roto i te ahumahi muka kiriaku, Kei te nuinga whakamahia te reira mo te hanga miro maroke o muka kiriaku;Ka whakamahia i roto i te umanga pesticide ki te whakahiato i te pai me te iti o te paitini pesticide pesticide;Ka whakamahia hei whakarewa waikano i roto i te ahumahi waikano;Te whakakore i nga waahanga tiini me te horoi i nga papa taiawhio i roto i te ahumahi hiko;Ko etahi atu ahumahi ko nga kaikawe hau morearea, nga whakarewa mo te whakamaaramatanga tarukino, nga taapiri, aha atu.

Ingoa matū: N, N-dimethylacetamide

Ko te Dimethylacetamide he whakarewa kaha kore protonated polar ka taea te whakakore i nga momo pūhui, ka uru katoa ki te wai, ethers, ketones, esters, me etahi atu.He pai te whakarewatanga mo nga momo kapia, ina koa te kapia polyurethane me te kapia polyimide, ka taea te whakamahi hei whakarewa mo nga muka waihanga wera-wera, kiriata kirihou, paninga, rongoa, me te miro acrylonitrile.Ko te Dimethylacetamide, he iti te paitini, he nui te kohua, me te polarity teitei kore proton solvent me te takawaenga matū, e whakamahia nuitia ana i roto i nga mara penei i nga rauemi waihanga, rongoa, pesticides, muka matū, tukatuka hinu, me nga whakangao waro.

He aha nga whakamahinga matua o te dimethyl formamide?

01whakamahia hei reagent tātari me te whakarewa mo te ethylene resin me te acetylene

02he whakarewa pararopi tino pai e whakamahia ana hei whakarewa mo te polyurethane, polyacrylonitrile, me te polyvinyl chloride, me te mea ano hei rauemi mata mo nga tangohanga, rongoa, me nga pesticides penei i te imidacloprid

03Ko te Dimethylformamide ehara i te mea he rawa matū e whakamahia nuitia ana, engari he whakarewa pai me te maha o nga whakamahinga.Ko te Dimethylformamide he whakarewa pai mo nga momo polymers teitei penei i te polyethylene, te polyvinyl chloride, te polyacrylonitrile, te polyamide, me etahi atu.Whakamahia mo te hanga kiriata kirihou;Ka taea hoki te whakamahi hei tango peita mo te tango peita;Ka taea hoki e ia te whakakore i etahi poaka wairewa iti, ka hoatu nga ahuatanga o te waikano.Ka whakamahia te Dimethylformamide mo te tangohanga waiwaro kakara, me te wehe me te whakaora i te butadiene mai i te hautanga C4 me te isoprene mai i te hautanga C5.Ka taea hoki te whakamahi hei reagent whai hua mo te wehe i nga waahanga waiwaro kore mai i te paraffin.He pai te whiriwhiri mo te whakarewatanga o te waikawa isophthalic me te waikawa terephthalic: he nui ake te wairewa o te waikawa isophthalic i roto i te dimethylformamide i tera i roto i te waikawa terephthalic.Ka taea e te tangohanga whakarewa, te whakatioatanga wahanga ranei i te dimethylformamide te wehe i nga mea e rua.I roto i te umanga petrochemical, ka taea te whakamahi te dimethyl formamide hei whakangao hau mo te wehe me te para o nga hau.I roto i nga tauhohenga waro, kaore i te whakamahia noa te dimethylformamide hei whakarewa, engari he takawaenga nui ki te whakahiato waro.Ka taea te whakamahi ki te whakaputa i nga chlorpyrifos i roto i te umanga pesticide;I roto i te ahumahi rongoa, ka taea te whakamahi ki te whakahiato i te pyrimidine iodide, doxycycline, cortisone, huaora B6, iodoside, Qubijing, thiapyrimidine, N-formyl sarcolysin, waikawa antineoplastic, methoxyaromaine, bianzapine, cyclohexanone nitrourea, mete furxyhasone nitrourea, mete furxyhasone nitrourea, mete furxyhasone, methoxyaromaine. , biliveratrol, chlorpheniramine, me etahi atu.Ka whai waahi a Dimethylformamide ki roto i te hauwai, te whakaheke, te whakamakuku, me nga tauhohenga dehalogenation, te whakaheke i te pāmahana tauhohenga me te whakapai ake i te ma o te hua.

04Kore reagent wairewa titration reagent, whakarewa mo te ethylene resin me te acetylene, te whakahiato pararopi, te whakaahua, te hau chromatography waahi noho (te teitei o te pāmahana whakahaere 50 ℃, te whakarewa methanol), te wehenga me te tātaritanga o te waiwaro C2-C5, me te kaha ki te wehe noa, isobutene , cis, me te trans butene.Te tātari toenga pesticide.Te whakahiato pararopi.Te whakahiato peptide.Whakamahia i roto i te ahumahi whakaahua.
