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

1.1,3-Dimethyl-2-imidazolidinone ntchito kuphunzira functionalized hydrosilane dibasic kusintha zitsulo maofesi okhazikika ndi photochemical mapangidwe aryl silanes.

2. Aprotic dipolar solvent, 1,3-dimethyl-2-imidazolidinone nthawi zambiri amagwiritsidwa ntchito monga carcinogen HMPA m'malo.

3. Zosungunulira zochita

Chifukwa cha kukhazikika kwake kwamatenthedwe ndi mankhwala, DMI imakhala ndi kusungunuka muzinthu zachilengedwe, zopangira organic ndi ma resins osiyanasiyana, ndipo zotsatira zake zothandizira monga zosungunulira zopanda protonic zimapangitsa kuti ikhale yosungunulira kwambiri. . Pogwiritsa ntchito DMI, zokolola zitha kupitilizidwa bwino ndipo zotsatira zake zitha kuwongoleredwa bwino ndikufupikitsa nthawi yochitira.

DMI imatha kulimbikitsa machitidwe osiyanasiyana a nucleophilic substitution, monga kaphatikizidwe ka phenyl ether, mankhwala amino ndi fluorobenzene. Kusungunuka kwake kwapamwamba kwambiri kwa dielectric ndi cationic kumatha kuyambitsa ma anionic nucleophilic reaction. Zopangira izi zimagwiritsidwa ntchito ngati zopatsirana pakupanga mankhwala ophera tizilombo, mankhwala, utoto ndi ma monomers apamwamba kwambiri a resin.

4. Mafuta amafuta

DMI ili ndi malo otentha kwambiri komanso kukhazikika kwa kutentha kwambiri, ndipo sikophweka kupanga azeotropes ndi zinthu zina. Choncho, angagwiritsidwe ntchito njira zambiri mafakitale monga madzi-zamadzimadzi m'zigawo, countercurrent kugawa, extractive distillation ndi countercurrent kusamba. DMI ndi mankhwala abwino a BTX (benzene, toluene ndi xylene) chifukwa amasungunula mankhwala onunkhira komanso ma hydrocarboni osakwanira, koma samasungunula parafini.

5. Polima anachita zosungunulira

DMI ndiye chosungunulira chokhacho chomwe chimagwiritsidwa ntchito popanga thermoplastics yosagwira kutentha. Amagwiritsidwanso ntchito bwino ngati zosungunulira zosiyanasiyana polima kaphatikizidwe njira ndi detergent kwa polymerization ndi akamaumba pulasitiki. Popanga polyamide ndi polyimide resins, DMI imathandizira mapangidwe a amide ndi imine magulu kuti apeze ma polima olemera kwambiri a molekyulu, ndipo yankho lake ndiloyenera kupota njira yothetsera kutentha kwa polyimide.

Popanga polyphenylene sulfide resin (PPS), zida zamagetsi zokhala ndi zonyansa zochepa kwambiri zitha kupezeka ndi DMI. Popanga polyphenylene etha sulfone resin, DMI imatha kuwongolera bwino zomwe zimachitika m'mbali ndikupeza zinthu zama polima apamwamba kwambiri. Pamene utomoni wa polyimide ndi utomoni wa polysulfone umapangidwa kukhala mafilimu ndipo mafilimu a polyether ketone resin amatambasulidwa, chithandizo cha DMI chingapangitse mafilimu kukhala ofanana.

6. Photolithography process stripper

Chifukwa cha kukhuthala kwake kochepa komanso kukhazikika kwa dielectric, DMI ikhoza kugwiritsidwa ntchito ngati chosungunulira cha electrolyte pamabatire a lithiamu apamwamba kwambiri. Kuphatikiza apo, imakhala ndi mphamvu yopitilira, malo otentha kwambiri komanso kukana kutentha kwambiri, ndipo itha kugwiritsidwanso ntchito ngati chovulira cha silicon wafer photoresist. Kuchotsa kwake mwachangu komanso kosawononga kumathandizira kwambiri kuvula ndikufulumizitsa kutulutsa kwa chip.

7. Chotsukira

DMI amawonjezeredwa kusakaniza kwa surfactants, alkalis, alcohols ndi polyoxyethylene alkyl ethers kuti apeze chotsukira champhamvu. Popeza DMI ndiyosavuta kusungunula dothi, itha kugwiritsidwanso ntchito pokonzekera njira zoyeretsera zotsuka magalasi ndi zitsulo.

8. Utoto ndi utoto

Ma inki opangidwa ndi kusakaniza DMI ndi zosungunulira zigawo ndi utoto ndi pigment akhoza kusindikizidwa mosiyana, ndipo chithunzi ndi bwino.

9. Wothandizira chithandizo chapamwamba

DMI angagwiritsidwe ntchito ngati pamwamba mankhwala wothandizira kusintha mphamvu yomangira ABS, polyimide, PPS, Teflon ndi zipangizo zina ndi zomatira epoxy utomoni.
