whakaahuatanga poto:

Ko te wahanga N,N-dimethyl carapace he whakarewa onge.He hygroscopic nga matūriki Microchloride ka taea te hygroscopic.Ka uru te tangohanga ki etahi momo whakarewa pararopi penei i te waiwaro, te maaota me te wai ethyl, he matū paku nei.
Te wai kore tae me te wai marama.He whakarewa waikore polar.Hāunga ngā hauwai hauhā, ka taea te konatunatua noa ki te wai me te nuinga o nga whakarewa waro.
1) Ko te whakarewa pararopi tino pai, whakamahia hei whakarewa mo te polyurethane Chemicalbook ester, polyacrylonitrile, me te polyvinyl chloride, me te mea ano he rauemi mata mo nga tangohanga, rongoa me nga pesticides.
2) Ka whakamahia hei reagent tātari me te whakarewa mo te kapia vinyl me te acetylene
3) Te whakarewa titration kore-wai.

1. He whakarewa pararopi tino pai, whakamahia hei whakarewa mo te polyurethane, polyacrylonitrile, me te polyvinyl chloride.Ka whakamahia ano hei rauemi mata mo nga tangohanga, rongoa me nga pesticides.

2. Ka whakamahia hei reagent tātari me te whakarewa mo te kapia vinyl me te acetylene

3. Ko te Dimethylformamide ehara i te mea he rawa matū tino pai, engari he whakarewa pai rawa atu.Ko te Dimethylformamide he whakarewa pai mo nga momo polymers penei i te polyethylene, te polyvinyl chloride, te polyacrylonitrile, te polyamide, me etahi atu, ka taea te whakamahi mo te miro maku o nga muka waihanga penei i te muka polyacrylonitrile, me te whakahiato o te polyurethane;Whakamahia i roto i te hanga kiriata kirihou;ka taea hoki te whakamahi hei tango peita hei tango i te peita;ka taea hoki e ia te whakakore i etahi poaka iti-wairewa, ka hoatu ki nga waikano nga ahuatanga o te waikano.Ka whakamahia te Dimethylformamide mo te tangohanga kakara me te wehenga 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 kore-waiwai mai i te paraffin..He pai te whiriwhiri ki te wairewa o te waikawa isophthalic me te waikawa terephthalic: he nui ake te wairewa o te waikawa isophthalic i roto i te dimethylformamide i te waikawa terephthalic.Ka mahia e te Chemicalbook te tangohanga whakarewa, te whakatioatanga Waahanga ranei ka wehe i nga mea e rua.I roto i te umanga petrochemical, ka taea te whakamahi i te dimethylformamide hei whakangao hau hei wehe me te whakamahine i te hau.I roto i nga tauhohenga waro, kaore i te whakamahia whanuitia te dimethylformamide hei whakarewa mo te tauhohenga, engari he takawaenga nui ano hoki mo te whakahiato waro.I roto i te ahumahi pesticide, ka taea te whakamahi ki te whakaputa ngarara;i roto i te ahumahi rongoa, ka taea te whakamahi ki te whakahiato iodosamine, doxycycline, cortisone, huaora B6, iodoside, ququjing, pyrantel, N-formyllysar Onumaric acid, methoxy mustard, chlorambucil, nitrosourea, furfurouracil, tranexamic acid, violetges, violethasone chlorpheniramine, me etahi atu. Ko te Dimethylformamide he painga whakangao i roto i nga tauhohenga o te hauwai, te whakaheke, te whakamaroketanga me te dehydrohalogenation, e whakaiti ana i te pāmahana tauhohenga me te whakapai ake i te ma o te hua.

4.Titration o nga whakarewa kore-wai.Te whakarewa mo te kapia vinyl me te acetylene.Te whakatau whakaahua.Ko te wai chromatographic hau (te nui o te whakamahi i te pāmahana 50 ℃, te whakarewa he methanol), wehea te Chemicalbook hei tātari C2-C5 waiwaro, ka taea te wehe noa me te isobutene me te cis me te trans-2-butene.Te tātari i nga toenga pesticide.Te Whakakotahitanga Organic.Te whakahiato o nga peptides.Mo te ahumahi whakaahua.
