Iyini i-1,3-Dimethyl-2-imidazolidinone CAS 80-73-9?

I-1,3-Dimethyl-2-imidazolidinone, eyaziwa nangokuthi i-dimethylethylene urea, efushanisiwe njenge-1,3-dimethyl-2-imidazolidinone, i-solvent ye-polar enephuzu eliphezulu lokubilisa, i-flash point, indawo encibilikayo ephansi, ubuthi obuphansi kakhulu, ukungcola okuphansi kakhulu kanye ne-solubility enamandla. Inokuqina okuqinile futhi imelana nama-acids aqinile, ama-alkali aqinile, amanzi, ukukhanya nomoya-mpilo.

Isicelo

I-1.1,3-Dimethyl-2-imidazolidinone isetshenziselwa ukutadisha izakhiwo zensimbi ze-hydrosilane dibasic transition eziqinisiwe ngokubunjwa kwe-photochemical ye-aryl silanes.

2. I-Aprotic dipolar solvent, i-1,3-dimethyl-2-imidazolidinone ivame ukusetshenziswa njenge-carcinogen HMPA esikhundleni.

3. Isixazululi sokusabela

Ngenxa yokuqina kwayo okuhle kakhulu kwe-thermal kanye namakhemikhali, i-DMI inokuncibilika kuma-inorganic, ama-organic compounds nama-resin ahlukahlukene, futhi umphumela wayo we-catalytic njenge-non-protonic polar solvent kuyenza i-solvent yokusabela ephumelelayo ngokukhethekile. . Ngokusebenzisa i-DMI, isivuno singathuthukiswa futhi ukusabela okuseceleni kungalawulwa ngempumelelo ngenkathi kufinyezwa isikhathi sokusabela.

I-DMI ingaphromotha ngempumelelo ukusabela okuhlukile kwe-nucleophilic esikhundleni, njengokuhlanganiswa kokuphuma kokunye kwe-phenyl ether, izinhlanganisela ze-amino nokuphuma kokunye kwe-fluorobenzene. Ukuxazululwa kwayo okuphezulu kwe-dielectric njalo kanye ne-cationic kungabangela ukusabela kwe-nucleophilic anionic. Le mikhiqizo yokwenziwa isetshenziswa njengezimaphakathi zokuhlanganiswa kwezibulala-zinambuzane, izidakamizwa, odayi kanye nama-monomers e-resin asebenza kahle kakhulu.

4. Imikhiqizo kaphethiloli

I-DMI inezinga eliphezulu lokubilisa kanye nokuzinza okuphezulu kokushisa, futhi akulula ukwenza i-azeotropes nezinye izinto. Ngakho-ke, ingasetshenziswa ezinqubweni eziningi zezimboni ezifana nokukhishwa kwe-liquid-liquid, ukusatshalaliswa kwe-countercurrent, i-distillation ekhishwayo kanye nokugeza okuphambene. I-DMI iyisithako esihle se-BTX (i-benzene, i-toluene nexylene) ngoba sincibilikisa izinhlanganisela ezinuka kamnandi nama-hydrocarbon angagcwele, kodwa ayincibilikisi upharafini.

5. I-Polymer reaction solvent

I-DMI ukuphela kwento encibilikayo esetshenziselwa ukukhiqiza ama-thermoplastic angangeni ekushiseni. Ibuye isetshenziswe ngempumelelo njengesinyibilikisi sezinqubo ezahlukahlukene ze-polymer synthesis kanye nesihlanzi se-polymerization kanye nokubumba kwepulasitiki. Ekukhiqizeni ama-polyamide kanye ne-polyimide resins, i-DMI isheshisa ukwakheka kwamaqembu e-amide nama-imine ukuze kutholwe ama-polymers esisindo samangqamuzana aphezulu, futhi isisombululo esiwumphumela sifanelekile ukuphotha kwesisombululo ukuze kutholwe imicu ye-polyimide ephikisana nokushisa ephezulu.

Ekukhiqizeni i-polyphenylene sulfide resin (PPS), izinto ze-elekthronikhi ezinenani elincane kakhulu lokungcola okuphilayo zingatholwa yi-DMI. Ekukhiqizeni i-polyphenylene ether sulfone resin, i-DMI ingakwazi ukulawula ngempumelelo ukuvela kokusabela okusemaceleni futhi ithole imikhiqizo ye-polymer yekhwalithi ephezulu. Lapho i-polyimide resin ne-polysulfone resin kwakhiwa abe amafilimu futhi amafilimu e-polyether ketone resin anwetshiwe, ukwelashwa nge-DMI kungenza amafilimu afane kakhulu.

6. I-stripper yenqubo ye-Photolithography

Ngenxa ye-viscosity yayo ephansi kanye nokungaguquki okuphezulu kwe-dielectric, i-DMI ingasetshenziswa njenge-solvent ye-electrolyte yamabhethri e-lithium asebenza kahle. Ngaphezu kwalokho, inokungena okuqinile, indawo yokubilisa ephezulu kanye nokumelana nokushisa okuphezulu, futhi ingasetshenziswa njengesihluthulelo se-silicon wafer photoresist. Ukuhlubula kwayo okusheshayo nokungagqwali kwenza kube lula kakhulu inqubo yokuhlubula futhi kusheshise ukukhiqiza kokusika kwe-chip.

7. Okokuhlanza

I-DMI yengezwa engxubeni yama-surfactants, ama-alkali, utshwala nama-polyoxyethylene alkyl ethers ukuze kutholwe okokuhlanza okunamandla. Njengoba i-DMI ilula kakhulu ukuncibilikisa ukungcola, ingasetshenziswa futhi ukulungisa izixazululo ezisebenzayo zokuhlanza ingilazi nensimbi.

8. Odayi nezingulube

Oyinki abenziwe ngokuxuba i-DMI nezingxenye ze-solvent kanye namadayi nama-pigments angaphrintwa ngokuphambene, futhi isithombe sicacile.

9. I-ejenti yokwelapha ebusweni

I-DMI ingasetshenziswa njenge-ejenti yokwelapha engaphezulu ukuze kuthuthukiswe amandla okubopha we-ABS, i-polyimide, i-PPS, i-Teflon nezinye izinto ezine-epoxy resin adhesives.
