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

I-1.1,3-Dimethyl-2-imidazolidinone isetshenziselwa ukutadisha ama-hydrosilane dibasic transition metal complexes aqiniswe ngokwakhiwa kwe-aryl silanes nge-photochemical.

2. I-aprotic dipolar solvent, i-1,3-dimethyl-2-imidazolidinone ivame ukusetshenziswa njengesithasiselo se-HMPA esibangela umdlavuza.

3. Isinyibilikisi sokusabela

Ngenxa yokuqina kwayo okuhle kakhulu kokushisa namakhemikhali, i-DMI inokuncibilika kuma-inorganic compounds kanye nama-resin ahlukahlukene, futhi umphumela wayo wokuvuselela njenge-non-protonic polar solvent yenza kube yi-reaction solvent ephumelela kakhulu. . Ukusebenzisa i-DMI, isivuno singathuthukiswa futhi ukusabela okuseceleni kungalawulwa ngempumelelo ngenkathi kufinyezwa isikhathi sokusabela.

I-DMI ingakhuthaza ngempumelelo ukusabela okuhlukahlukene kokushintshana kwe-nucleophilic, njengokwenziwa kwe-phenyl ether derivatives, ama-amino compounds kanye ne-fluorobenzene derivatives. I-dielectric yayo ephezulu kanye ne-cationic solvation yayo ingakhuthaza ukusabela kwe-anionic nucleophilic. Le mikhiqizo yokwenziwa isetshenziswa njengezinto ezihlanganisa ukwakheka kwezibulala-zinambuzane, izidakamizwa, udayi kanye nama-resin monomers asebenza kahle.

4. Imikhiqizo kaphethiloli

I-DMI inezinga eliphezulu lokubila kanye nokuqina okuphezulu kokushisa, futhi akulula ukwenza ama-azeotropes nezinye izinto. Ngakho-ke, ingasetshenziswa ezinqubweni eziningi zezimboni njengokukhipha uketshezi oluyi-liquid, ukusatshalaliswa kwe-countercurrent, ukuhluzwa kokukhipha kanye nokuwasha kwe-countercurrent. I-DMI iyi-extractant enhle ye-BTX (benzene, toluene kanye ne-xylene) ngoba incibilikisa ama-compounds aromatic kanye nama-hydrocarbon angagcwalisiwe, kodwa ayincibilikisi i-paraffin.

5. Isinyibilikisi sokusabela kwe-polymer

I-DMI iyona kuphela i-solvent esetshenziselwa ukukhiqiza ama-thermoplastics angashisi. Iphinde isetshenziswe ngempumelelo njenge-solvent yezinqubo ezahlukahlukene zokwenziwa kwe-polymer kanye ne-detergent yokwenza i-polymerization kanye nokubumba ipulasitiki. Ekukhiqizweni kwama-resin e-polyamide kanye ne-polyimide, i-DMI isheshisa ukwakheka kwamaqembu e-amide kanye ne-imine ukuze kutholakale ama-polymers anesisindo sama-molecule aphezulu, futhi ikhambi elivelayo lifanelekela ukusonta ikhambi ukuze kutholakale imicu ye-polyimide engashisi kakhulu.

Ekukhiqizweni kwe-polyphenylene sulfide resin (PPS), izinto zikagesi ezinenani elincane kakhulu lokungcola okungokwemvelo zingatholakala nge-DMI. Ekukhiqizweni kwe-polyphenylene ether sulfone resin, i-DMI ingalawula ngempumelelo ukwenzeka kwemiphumela emibi futhi ithole imikhiqizo ye-polymer esezingeni eliphezulu. Lapho i-polyimide resin kanye ne-polysulfone resin kwakheka amafilimu futhi amafilimu e-polyether ketone resin enwetshwa, ukwelashwa nge-DMI kungenza amafilimu afane kakhulu.

6. I-Photolithography process stripper

Ngenxa ye-viscosity yayo ephansi kanye ne-dielectric constant ephezulu, i-DMI ingasetshenziswa njengesithako se-electrolyte samabhethri e-lithium asebenza kahle kakhulu. Ngaphezu kwalokho, inokungena okunamandla, izinga lokubila eliphezulu kanye nokumelana nokushisa okuphezulu, futhi ingasetshenziswa njengesithako se-silicon wafer photoresist. Izakhiwo zayo zokususa ngokushesha kanye nezingaboli zenza kube lula kakhulu inqubo yokususa futhi isheshise umkhiqizo wokusika ama-chip.

7. Isitsha sokuhlanza

I-DMI ifakwa engxubeni yama-surfactants, ama-alkali, ama-alcohols kanye nama-polyoxyethylene alkyl ethers ukuze kutholakale insipho enamandla. Njengoba i-DMI kulula kakhulu ukuyincibilikisa ukungcola, ingasetshenziswa futhi ukulungiselela izixazululo zokuhlanza ezisebenzayo zokuhlanza ingilazi nensimbi.

8. Amadayi nemibala

Uyinki owenziwe ngokuxuba i-DMI nezingxenye zesinyibilikisi kanye nodayi nemibala kungaphrintwa ngokuphambene, futhi isithombe sicacile.

9. I-ejenti yokwelapha ubuso

I-DMI ingasetshenziswa njenge-ejenti yokwelapha ubuso ukuze kuthuthukiswe amandla okubopha e-ABS, i-polyimide, i-PPS, i-Teflon nezinye izinto ezinamathelayo ze-epoxy resin.
