Isicelo

I-1.1,3-Dimethyl-2-imidazolidinone isetyenziselwa ukufunda i-functionalized hydrosilane dibasic transition metal complexes ezinziswe yi-photochemical formation ye-aryl silanes.

2. I-aprotic dipolar solvent, i-1,3-dimethyl-2-imidazolidinone isoloko isetyenziswa njenge-carcinogen substitute HMPA.

3. Isinyibilikisi esisabelayo

Ngenxa yozinzo olugqwesileyo lwe-thermal kunye neekhemikhali, i-DMI ine-solubility kwi-inorganic, i-organic compounds kunye nee-resin ezahlukeneyo, kunye nefuthe layo elisebenzayo njenge-non-protonic polar solvent yenza ukuba i-solvent esebenzayo yokuphendula. . Ukusebenzisa i-DMI, isivuno sinokuphuculwa kwaye iimpendulo zecala zingalawulwa ngokufanelekileyo ngelixa unciphisa ixesha lokuphendula.

I-DMI inokukhuthaza ngempumelelo iintshukumo ezahlukeneyo ze-nucleophilic substitution, ezifana ne-synthesis ye-phenyl ether derivatives, i-amino compounds kunye ne-fluorobenzene derivatives. I-dielectric ephezulu engaguqukiyo kunye ne-cationic solvation inokwenza i-anionic nucleophilic reactions. Ezi mveliso zokwenziwa zisetyenziswa njengeziphakathi kwi-synthesis ye-pesticides, iziyobisi, iidayi kunye ne-high-performance resin monomers.

4. Iimveliso zepetroleum

I-DMI ineqondo eliphezulu lokubilisa kunye nokuzinza okuphezulu kwe-thermal, kwaye akulula ukwenza i-azeotropes kunye nezinye izinto. Ngoko ke, inokusetyenziswa kwiinkqubo ezininzi zoshishino ezifana ne-liquid-extraction, i-countercurrent distribution, i-extractive distillation kunye ne-countercurrent washing. I-DMI sisitsalo esilungileyo se-BTX (i-benzene, i-toluene kunye nexylene) kuba inyibilikisa iikhompawundi ezinevumba elimnandi kunye neehydrocarbon ezingaxutywanga, kodwa ayinyibilikisi iparafini.

5. I-solvent ye-polymer reaction

I-DMI kuphela kwesinyibilikisi esisetyenziselwa ukuvelisa i-thermoplastics ekwazi ukumelana nobushushu. Ikwasetyenziswa ngokufanelekileyo njengesinyibilikisi kwiinkqubo ezahlukeneyo ze-polymer synthesis kunye ne-detergent ye-polymerization kunye nokubumba iplastiki. Kwimveliso ye-polyamide kunye ne-polyimide resins, i-DMI ikhawuleza ukubunjwa kwe-amide kunye namaqela e-imine ukufumana i-polymers ephezulu ye-molecular weight, kwaye isisombululo esisiphumo sifanelekile kwisisombululo sokujikeleza ukufumana i-high-temperature resistant polyimide fibers.

Kwimveliso ye-polyphenylene sulfide resin (PPS), izinto ze-elektroniki ezinomlinganiselo omncinci wokungcola kwezinto eziphilayo zingafunyanwa yi-DMI. Kwimveliso ye-polyphenylene ether sulfone resin, i-DMI inokulawula ngokufanelekileyo ukwenzeka kweempendulo zecala kunye nokufumana iimveliso zepolymer ezikumgangatho ophezulu. Xa i-polyimide resin kunye ne-polysulfone resin zenziwe kwiifilimu kunye neefilimu ze-polyether ketone resin zoluliwe, unyango nge-DMI lunokwenza iifilimu zibe zifanayo.

6. I-stripper yenkqubo ye-Photolithography

Ngenxa ye-viscosity ephantsi kunye ne-dielectric rhoqo, i-DMI ingasetyenziselwa njenge-solvent ye-electrolyte kwiibhetri ze-lithium eziphezulu. Ukongeza, inokungena okuqinileyo, indawo yokubilisa ephezulu kunye nokumelana nobushushu obuphezulu, kwaye inokusetyenziswa njenge-stripper ye-silicon wafer photoresist. Iipropati zayo ezikhawulezayo zokuhlutha kunye ne-non-corrosion zilula kakhulu inkqubo yokuhlutha kwaye ikhawuleze imveliso yokusika i-chip.

7. Isicoci

I-DMI yongezwa kumxube we-surfactants, i-alkalis, i-alcohol kunye ne-polyoxyethylene alkyl ethers ukufumana isicoci esinamandla. Ekubeni i-DMI ilula kakhulu ukunyibilikisa ukungcola, ingasetyenziselwa ukulungiselela izisombululo zokucoca ngokufanelekileyo zokucoca iglasi kunye nesinyithi.

8. Idayi kunye nee-pigments

Iinki ezenziwe ngokuxuba i-DMI kunye namacandelo e-solvent kunye nedayi kunye ne-pigments inokuprintwa ngokungafaniyo, kwaye umfanekiso ucacile.

9. Iarhente yonyango lomphezulu

I-DMI ingasetyenziselwa njenge-arhente yonyango lomphezulu wokuphucula amandla okubambisana kwe-ABS, i-polyimide, i-PPS, i-Teflon kunye nezinye izinto ezine-epoxy resin adhesives.
