Dimethyl carbonate

Gawo Loyamba: Kufotokozera  za Dimethyl carbonate (DMC)

Zamadzimadzi zopanda mtundu zowonekera komanso fungo lamphamvu. Sasungunuke m'madzi, sungunuka mu zosungunulira organic monga ethanol ndi ether. Zomwe zimatchedwanso DMC, Methyl Carbonate, Methyl Carbonate, Dimetyl Carbonate, Dimethyl Carbonate.CAS No.616-38-6, EINECS:210-478-4 Chemical Formula:C3H6O3

Gawo Lachiwiri Kugwiritsa Ntchito Dimethyl carbonate (DMC)

1. Makampani opanga utoto, zokutira ndi zomatira

Chifukwa cha kusungunuka kwake kwakukulu, kusungunuka kocheperako komanso kuwira kwapakati, kugwedezeka kwakukulu, kutsika kwa viscosity, ndi dielectric yaing'ono yosasinthasintha, dimethyl carbonate imatha kusintha mankhwala a toluene ndi xylene ndipo amagwiritsidwa ntchito kwambiri mu utoto wapamwamba, zokutira, zomatira, ndi zina zotero. Glue ndi mafakitale ena.

2. Makampani a polycarbonate

Dimethyl carbonate imagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana zachilengedwe ndipo pang'onopang'ono imalowa m'malo mwa phosgene popanga polycarbonate ndi isocyanate, yomwe ili ndi kusiyana kwakukulu pamsika. Polycarbonate ndi chinthu chodziwika bwino chatsiku ndi tsiku chokhala ndi kukana kwambiri. Ndi chinthu chokhacho chomwe chimawonekera bwino pakati pa mapulasitiki akuluakulu asanu a engineering. Ndiwonso pulasitiki yaukadaulo yomwe ikukula mwachangu kwambiri m'zaka zaposachedwa. Pakali pano amagwiritsidwa ntchito kwambiri pamagalimoto, zamagetsi ndi zamagetsi, zomangamanga, zipangizo zamaofesi, zonyamula katundu, zipangizo zamasewera, chithandizo chamankhwala ndi zina. Ndikukula kosalekeza kwa kafukufuku wosintha, ikukula mwachangu m'magawo apamwamba kwambiri monga zakuthambo, makompyuta, ma disc owonera ndi zina zotero.

3. Batri ya lithiamu-ion electrolyte

Ndi kukhazikitsidwa mosalekeza kwa dongosolo dziko latsopano mphamvu makampani, ndi magetsi mopeds ndi magalimoto magetsi msika, motsogozedwa ndi dziko latsopano mphamvu njira, Dimethyl carbonate kukhala imodzi mwa mafakitale ndi chiyembekezo kwambiri msika mu dziko langa m'tsogolo. Momwemonso, kutulutsa ndi kufunikira kwamakampani a batri a lithiamu nawonso akuwonjezeka. Kukula mwachangu. Monga chimodzi mwazinthu zazikulu zopangira ma electrolyte a batri, zinthu za carbonate zidzakula mwachangu pamabatire a lithiamu.

4. Mafuta owonjezera

Chifukwa cha kuchuluka kwa okosijeni (oxygen 53%, katatu kuposa MTBE) ndi kuthamanga kwa nthunzi koyenera, kukana madzi ndi kusakaniza kofanana kogawa, Dimethyl carbonate ingagwiritsidwe ntchito ngati mafuta abwino / dizilo zowonjezera kulimbikitsa kuyaka ndi kuonjezera octane. mtengo, kuchepetsa mpweya wa carbon, ndipo nthawi yomweyo kusintha odana kugogoda ntchito mafuta / dizilo.

5. Makampani opanga mankhwala

Makampani opanga mankhwala pakadali pano ndi malo ofunikira omwe amamwa dimethyl carbonate m'dziko langa. Mankhwala, dimethyl carbonate amagwiritsidwa ntchito makamaka ngati methylating agent kuti alowe m'malo oopsa kwambiri a dimethyl sulfate, ndipo amagwiritsidwa ntchito popanga mankhwala odana ndi matenda, antipyretics ndi analgesics. mankhwala, mavitamini, ndi mankhwala apakati amanjenje.

6. Mankhwala ophera tizilombo

dziko langa ndilopanga kwambiri mankhwala ophera tizilombo. Pamene chiwongolero cha kusintha kwa kachitidwe ka mafakitale a mankhwala ophera tizilombo m’dziko langa chikufulumira, zofunika za dziko kaamba ka chitetezo cha mankhwala ophera tizilombo zidzakhala zokhwimitsa kwambiri. Mankhwala ophera tizirombo amtundu wapoizoni pang'onopang'ono adzalowedwa m'malo ndi mankhwala opanda poizoni komanso otsika poyizoni. Chifukwa chake, ngati wobiriwira Kugwiritsa ntchito zinthu zapakatikati mwachilengedwe za dimethyl carbonate popanga mankhwala ophera tizilombo kudzakhala ndi chiyembekezo chokulirapo.

7. ADC utomoni

Allyl diglycol carbonate (ADC) ili ndi mawonekedwe abwino kwambiri owoneka bwino, kukana kuvala, kukana mabakiteriya, komanso kulemera kopepuka. Ndi utomoni wa thermosetting. Itha kusintha magalasi ndikugwiritsidwa ntchito ngati magalasi owonera ndi zida za optoelectronic. Poyamba adapangidwa kuchokera ku propylene mowa, diethyl glycol ndi phosgene. Masiku ano, makampani nthawi zambiri amagwiritsa ntchito DMC m'malo mwa phosgene. Chifukwa DMC ndi yapoizoni yochepa komanso yosawononga, imachepetsa zofunikira zaukadaulo popanga zida, kasamalidwe ka magwiridwe antchito komanso kukonza zinyalala. Chofunika kwambiri, zinthu zamtengo wapatali zimatha kupangidwa mosavuta. Chifukwa chake, magawo atsopano monga kugwiritsidwa ntchito ngati zinthu zolondola za optoelectronic akutsegulidwa.
