Kaihanga Pai Utu N, N-DimethyFormamide (DMF) Cas 68-12-2

Kaihanga Pai utu n, N-DIMTHYLEFORMADE (DMF) Cas 68-12-2 Whakaahua Whakaahua

Whakaahuatanga poto:

N, n-dimethylormamide he wa poto i te DMF. He mea hanga i hangaia e te whakakapinga o te roopu hydroxyl o te waikawa ahua ma te roopu Dimethylamino, ko te tauira molecular ko te Hcon (CH3) 2. He koretake, he maamaa, he wai kohua me te rahi o te kakara me te ahua whanaunga o te 0.9445 (25 ° C). Melting Point -61 ℃. Pie Pio 12.8 ℃. Flash Point 57.78 ℃. Vapor Denessity 2.51. Te pehanga o te Vapor 0.49kpa (3.7mmHg25 ℃). Ko te tohu-aunoa ko te 445 ° C. Ko te rohe pahūtanga o te kohu me te ranunga hau ko te 2.2 ki te 15.2%. I roto i te keehi o te mura o te ahi me te wera nui, ka raru pea te whakakotahitanga me te pahū. Ka taea e ia te urupare ki te waikawa whanariki me te waikawa nitric ki te whakakii i te waikawa nitric tae noa ki te pahū. He mea pohehe ki te wai me te nuinga o nga whakarewa o te rauropi. He whakarewa noa mo nga tauhohenga matū. Pure N, n-dimethylormadide he kakara, engari ko te ahumahi-ahumahi-a-ringa n, n-dimethylorformamimimid he kakara ika.

whakaaturanga

Ko te ingoa ka puta mai i te mea ko te whakakapinga dimethtyy fiment (mania ki te waikawa ahua), a ko nga roopu methyl e tu ana i te N (Nitrogen) Atom. N, n-dimethylolormamid he polar tino kohua (hydrophililic whakarewa (tebook whakarewa, me te pukapuka chemical ka taea te whakatairanga i te miihini tauhohenga snom. N, n-dimethylorllomid e whakaputa ana ma te whakamahi i te waikawa ahua me te dimthylamine. N, n-dimethylorformamid kaore e mau (ina koa ki te pāmahana nui) i te aroaro o te konutai kaha, te waikawa kaha ranei, me te waikawa sulfuric ranei. He tino pumau i te rangi me te wa ka wera ki te kohua. Ka teitei ake te pāmahana i te 350 ℃, ka ngaro te wai me te whakaputa i te monoxide me te dimethylamine. N, n-dimethylorlolormamid he pai te whakarewa aporo, ka taea te rewa te nuinga o nga matū, te waipiro, te miihini, te mangere Ko te mutunga pai o te N, ko te N-dimethylollolformamid e karapoti ana i nga kohinga o Metyl, ka kore e taea e nga katote kino te whakatata, engari ko nga katote e pa ana ki a ia. Ko te aniana tahanga he nui ake te kaha i te anion kua whakatauhia. He maha nga tauhohenga Ionic he ngawari ake te kawe i roto i te N-DIMTHYLOMAMAMID mai i nga whakarewa tukatuka, hei tauira mo te hybodyolds i te pāmahana o te rūma, ka taea te whakaputa i nga mahi nui, tino pai te whakahiatotanga o nga emihia ana e te hunga e aukati ana.

Nga tono o te DMF

He pai te whakarewa o te DMF mo te maha o nga polyethylene, polyvinyl chloride, polyvinyl, polyvinyl, polyvide, me era atu, me te whakahiato o te polyurethane; Ka whakamahia mo te hanga kiriata kirihou; Ka taea hoki te whakamahi hei peita peita mo te tango peita; Ka taea hoki te whakakore i etahi o nga piihi iti-iti, kia whai ai nga poaka i nga ahuatanga o nga waikano. Kei te whakamahia te DMF mo te tangohanga a te porehu me te wehe me te whakaoranga i te hautau C4 me te isoprene mai i nga hautau C5, ka taea hoki te whakamahi hei utu mo te wehenga o nga waahanga kore-hydrocarbon mai i Paraffin. He pai te mohiotanga mo te ngoikore o te waikawa isophthalic me te waikawa isophthalic he nui ake i te DMF i te waikawa terephthalic. I roto i te umanga hinu, ka taea te whakamahi i te DMF hei hinu hau hei wehe me te whakamahine i nga hau. Hei kaihoko whakairo mo te horoi horoi pukapuka i te umanga polyurethane, ka whakamahia i roto i te hanga o te hiako kirihou maku; Ka rite ki te whakarewa i roto i te umanga muka kirika, ka whakamahia te nuinga i roto i te tipu tipu maroke o te muka kirika; I roto i te umanga hikohiko hei kukume i nga waahanga tin-papa me nga papa porowhita kei roto i nga rongoa o te tarukino, nga taapiri mo te rongoa o te tarukino, etc. He mea nui ki te takawaenga o te whakatipu. I roto i te umanga pesticide, ka taea te whakamahi ki te whakaputa i te ciprofloxacin; I roto i te umanga rongoā, ka taea te whakamahi ki te tarai i te Iodine, Doxycycline, Cortine, huaora, pyroneltin, nethoxyfe, Bepartame, Meiha, Bilevita, Chlorpheninemine, te hanga whanariki. Ko te DMF he kaupapa catalytic i roto i nga tauhohenga o te haukana, te mate huka, te ngoikore me te dehydrohalgegege, kia pai ai te pāmahana o te tauhohenga, ka pai ake te poke.
