1,3-Dimethyl-2-imidazolidinone CAS 80-73-9

1.1,3-Dimethyl-2-imidazolidinone imagwiritsidwa ntchito pophunzira ma functionalized hydrosilane dibasic transition metal complexes omwe amakhazikika ndi photochemical formation ya aryl silanes.

2. Aprotic dipolar solvent, 1,3-dimethyl-2-imidazolidinone nthawi zambiri imagwiritsidwa ntchito ngati cholowa m'malo mwa HMPA chomwe chimayambitsa khansa.

3. Zosungunulira zoyankha

Chifukwa cha kukhazikika kwake kwa kutentha ndi mankhwala, DMI imasungunuka mu zinthu zopanda chilengedwe, zachilengedwe ndi ma resini osiyanasiyana, ndipo mphamvu yake yothandiza ngati chosungunulira polar chosakhala cha protonic imapangitsa kuti ikhale chosungunulira chogwira mtima kwambiri. Pogwiritsa ntchito DMI, phindu lake likhoza kukwera ndipo zotsatira zake zoyipa zitha kulamulidwa bwino pamene zikufupikitsa nthawi yochitapo kanthu.

DMI imatha kulimbikitsa bwino machitidwe osiyanasiyana osinthira ma nucleophilic, monga kupanga ma phenyl ether derivatives, amino compounds ndi fluorobenzene derivatives. Kukhazikika kwake kwa dielectric komanso cationic solvation kumatha kuyambitsa ma anionic nucleophilic reactions. Zinthu zopangidwazi zimagwiritsidwa ntchito ngati zolumikizira popanga mankhwala ophera tizilombo, mankhwala, utoto ndi ma resin monomers apamwamba.

4. Zinthu zopangidwa ndi mafuta

DMI ili ndi kutentha kwambiri komanso kutentha kwake kumakhala kolimba, ndipo sikophweka kupanga ma azeotrope ndi zinthu zina. Chifukwa chake, ingagwiritsidwe ntchito m'mafakitale ambiri monga kuchotsa madzi ndi madzi, kugawa kwa ma countercurrent, kusungunuka kwa madzi ndi kutsuka ma countercurrent. DMI ndi BTX yabwino (benzene, toluene ndi xylene) chifukwa imasungunula zinthu zonunkhira ndi ma hydrocarbon osakhuta, koma siisungunula paraffin.

5. Chosungunulira cha polymer reaction

DMI ndiye chosungunulira chokhacho chomwe chimagwiritsidwa ntchito popanga ma thermoplastics osatentha. Chimagwiritsidwanso ntchito bwino ngati chosungunulira cha njira zosiyanasiyana zopangira ma polymer komanso chotsukira cha polymerization ndi pulasitiki. Pakupanga ma polyamide ndi ma polyimide resins, DMI imathandizira kupanga magulu a amide ndi imine kuti apange ma polima olemera kwambiri, ndipo yankho lotsatira limakhala loyenera kupota yankho kuti lipeze ulusi wa polyimide wosatentha kwambiri.

Pakupanga polyphenylene sulfide resin (PPS), zipangizo zamagetsi zokhala ndi zinthu zochepa kwambiri zodetsedwa zachilengedwe zitha kupezeka ndi DMI. Pakupanga polyphenylene ether sulfone resin, DMI imatha kuwongolera bwino zochitika zoyipa ndikupeza zinthu zapamwamba za polymer. Pamene polyimide resin ndi polysulfone resin zimapangidwa kukhala mafilimu ndipo mafilimu a polyether ketone resin amatambasulidwa, chithandizo ndi DMI chingapangitse mafilimuwo kukhala ofanana.

6. Chotsukira njira yojambulira zithunzi

Chifukwa cha kukhuthala kwake kochepa komanso kusasinthasintha kwa dielectric, DMI ingagwiritsidwe ntchito ngati chosungunulira cha electrolyte pamabatire a lithiamu omwe amagwira ntchito bwino. Kuphatikiza apo, ili ndi mphamvu yolowera, kutentha kwambiri komanso kukana kutentha kwambiri, komanso ingagwiritsidwenso ntchito ngati chotsukira cha silicon wafer photoresist. Kuchotsa mwachangu komanso kusawononga zinthu kumapangitsa kuti njira yochotsera zinthu ikhale yosavuta komanso imathandizira kudula kwa chip mwachangu.

7. Supu yotsukira

DMI imawonjezeredwa ku chisakanizo cha ma surfactants, alkalis, alcohols ndi polyoxyethylene alkyl ethers kuti ipange sopo wamphamvu. Popeza DMI ndi yosavuta kusungunula dothi, ingagwiritsidwenso ntchito pokonza njira zoyeretsera bwino magalasi ndi zitsulo.

8. Utoto ndi utoto

Inki zopangidwa posakaniza DMI ndi zinthu zosungunulira, utoto ndi utoto zimatha kusindikizidwa mosiyana, ndipo chithunzicho chimakhala chowonekera bwino.

9. Wothandizira kuchiza pamwamba

DMI ingagwiritsidwe ntchito ngati chothandizira pakhungu kuti iwonjezere mphamvu yolumikizirana ya ABS, polyimide, PPS, Teflon ndi zipangizo zina pogwiritsa ntchito zomatira za epoxy resin.
