Wopanga mtengo wabwino N, N-D-Dimethlfermamide (DMF) Cas 68-12-22

Kufotokozera kwaifupi:

N, n-dimethlfermormormide amafupikitsidwa ngati DMF. Ndi gawo lopangidwa ndi gulu la hydroxyl la formic acid ndi gulu la a Dimethylaminonio, ndipo ma molecular forla ndi HYC (CH3) 2. Ndiwopanda mafuta osawoneka bwino, owiritsa, owira fungo la Amine ndi kachulukidwe ka 0.9445 (25 ° C). Malo osungunuka -61 ℃. Owotcha 152.8 ℃. Kuwala kwa 57.78 ℃. Vapor vapor 2.51. Vapor kuthamanga 0.49kpa (3.7mhhg25 ℃). Malo oyimitsa a Auto ndi 445 ° C. Malire ophulika a nthunzi ndi mpweya wosakaniza ndi 2.2 mpaka 15.2%. Pankhani ya lawi lamoto wotseguka ndi kutentha kwambiri, zitha kuyambitsa kuyanjana komanso kuphulika. Itha kuchitira nkhanza acid acid acid ndi kuwononga nitric acid ndikuphulika. Ndizolakwika ndi madzi ndi okhazikika okhazikika. Ndi njira yodziwika bwino yamankhwala. Oyera n, N-Dimethlfermormide ndi wopanda fungo, koma kalasi ya mafakitale kapena kuwonongedwa n, fungo la itfithylfermormid ali ndi zodetsa za dimethylamine.

Dzinalo limachokera kuti ndilo matenda a madimethyl a cromethyl (aminede a acid), ndipo magulu onse a methyl ali pa n (nayitrogeni) atomu. N, N-Dimethlfermormamid ndi polar yotentha (hydrophilic) osungunuka, ndi mankhwala opangira mankhwala angalimbikitsenso pn2. N, N-Dimethlfermormamid amapangidwa pogwiritsa ntchito formic acid ndi dimethylamine. N, N-Dimethlfermormamid ndi osakhazikika (makamaka kutentha kwakukulu) Pamaso kwa mabasi olimba monga hydrochloric acid kapena ma hydrolyzos kuti akhale acid ndi dimethylamine. Ndiwokhazikika mlengalenga komanso atatenthedwa. Matenthedwe akakhala okwera kuposa 350 ℃, imataya madzi ndikupanga mpweya monoxide ndi Dimethlamine. N, N-Dimethlfermormid ndi po po poolant solar solvent, yomwe imatha kusungunula zinthu zopangidwa ndi zinthu zachilengedwe, ndipo ndizolakwika ndi madzi, malalanje, ma hydrocarbons, etc.. Kutha kwamphamvu kwa N, N-N-N-Nimethlfermormamid Molekyu kumazunguliridwa ndi magulu a methyl, ndikupanga cholepheretsa, kotero kuti zisungulu zopanda pake, koma anyezi yabwino yolumikizidwa. Anion wamaliseche ndi wakhama kwambiri kuposa anion yothekera. Zochitika zambiri za ionic zimachitika mosavuta mu n-y dimethylfermormid kapangidwe kake ka etterssite.

Ntchito za DMF

DMF ndi yosungunulira yabwino kwambiri monga polyethylene, polyvinyl chloride, polyacrylosidisiyi, polyamide, etc., ndi kapangidwe ka polyurethane; Imagwiritsidwa ntchito popanga mafilimu; Itha kugwiritsidwanso ntchito ngati chotola chopatuka utoto; Zimathanso kusungunula zigawenga zotsika kwambiri, kotero kuti zojambulazo zili ndi mawonekedwe a utoto. DMF imagwiritsidwa ntchito pokopera ndi kupatukana ndi kuchira kwa bunadiene kuchokera pa c400 ndi isoprene kuchokera ku zigawo za C5, ndipo imatha kugwiritsidwanso ntchito ngati reagent ya kulekanitsa kwa parafini. Ili ndi kusaka kwabwino kuti isungunulilililic acid ndi terephthalic acid ndi acid ambiri acid ndi terephthalic acid ndi terephthalic icid Mu secrochemical opanga, DMF imatha kugwiritsidwa ntchito ngati mpweya wodzipereka kupatula kupatukana ndi mpweya. Monga wothira wothandizira pakutsuka mankhwala mu polyureurethane, imagwiritsidwa ntchito popanga zikopa zonyowa; Monga zosungunulira m'mafashoni a acrylic-, amagwiritsidwa ntchito makamaka popanga masikono a ma acrylic. M'magetsi amagetsi ngati kupindika kwa magawo ophatikizika ndi mabwalo a masitepe ena amaphatikiza onyamula mabala owopsa, zomata, etc. Komanso wapakatikati pa synthesis. Pazomera zamankhwala, zitha kugwiritsidwa ntchito kutulutsa ciprofloxcin; M'makampani opangira mankhwala, itha kugwiritsidwa ntchito potengera ayodinisi, cortisone, vitamini B6, ayodini, a Itnodiazercine, herpodiarouracil, herpoflurotic acid, Bepartame, Megastrol, Bilevita, chlorpheniramine, sulfonamides. DMF ili ndi vuto lazovuta mu hydrogenation ya hydrogenation, deyydrogenation, madzi am'madzi ndi ma duydrogenation, kuti kutentha kwamomwe kumachepetsedwa ndipo chiyero chazosintha chimasinthidwa.

1. Ndizabwino kwambiri zosungunulira zachilengedwe, zomwe zimagwiritsidwa ntchito ngati zosungunulira kwa polyirethanean, polyvinyl chloride, komanso zogwiritsidwanso ntchito ngati zowonjezera zamankhwala ndi mankhwala ophera tizilombo.

2. Amagwiritsidwa ntchito ngati zosungunulira ndikusungunulira za vinyl retin ndi acetylene

3. Sikuti mankhwala opangira mankhwala okhaokha omwe ali ndi mitundu yambiri, komanso zosungunulira bwino kwambiri ndi kugwiritsa ntchito mitundu yambiri. DMF ndi yosungunulira yabwino kwambiri monga polyethylene, polyvinyl chloride, polyacrylosidisiyi, polyamide, etc., ndi kapangidwe ka polyurethane; Imagwiritsidwa ntchito popanga mafilimu; Itha kugwiritsidwanso ntchito ngati chotola chopatuka utoto; Zimathanso kusungunula zigawenga zotsika kwambiri, kotero kuti zojambulazo zili ndi mawonekedwe a utoto. DMF imagwiritsidwa ntchito pokopera ndi kupatukana ndi kuchira kwa bunadiene kuchokera pa c400 ndi isoprene kuchokera ku zigawo za C5, ndipo imatha kugwiritsidwanso ntchito ngati reagent ya kulekanitsa kwa parafini. Ili ndi kusaka kwabwino kuti isungunulililic acid ndi terephthalic acid ndi acid ambiri acid to acinethyl mankhwala a acid acid kapena pang'ono. Mu secrochemical opanga, DMF imatha kugwiritsidwa ntchito ngati mpweya wodzipereka kupatula kupatukana ndi mpweya. M'malo opangidwa, DMF sikuti amangogwiritsidwa ntchito ngati zosungunulira, komanso wapakatikati pazinthu zachilengedwe. Pazomera zamankhwala, zitha kugwiritsidwa ntchito kutulutsa ciprofloxcin; M'makampani opanga mankhwala, itha kugwiritsidwa ntchito posankha ayodini, doxycycline, cortisone, vitamini B6, ayoogen, pyrogen, pyrofle Bepartame, Bilevitamin, chlorpheniramine, etc. dmf ali ndi mphamvu yothandizira hydrogenation, kudzipha ndi ma dehydrogenation, kuteteza kwa malonda kumasinthidwa.

4.. Zosungunulira za vinyl ndi acetylene. Kutengera Kupanga Kutsimikiza. Gasi chromatographraphication yothetseratu (kokwanira pakugwiritsa ntchito mateyo 50 Kusanthula kwa mankhwala osokoneza bongo. Kapangidwe kabwino. Puti Yoyang'anira. Pazinthu zojambula.
