Isicelo

I-1.1,3-Dimethyl-2-imidazolidinone isetyenziselwa ukufunda ii-hydrosilane dibasic transition metal complexes ezizinzileyo ngokwenziwa kwe-aryl silanes nge-photochemical.

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

3. Isinyibilikisi sempendulo

Ngenxa yokuzinza kwayo okuhle kakhulu kobushushu kunye neekhemikhali, i-DMI inokunyibilika kwiikhompawundi ezingaphiliyo, eziphilayo kunye neeresini ezahlukeneyo, kwaye isiphumo sayo sokutsala njenge-non-protonic polar solvent senza ukuba ibe yi-reaction solvent esebenzayo kakhulu. . Ukusebenzisa i-DMI, isivuno sinokuphucuka kwaye iimpendulo ezisecaleni zinokulawulwa ngempumelelo ngelixa kuncitshiswa ixesha lokuphendula.

I-DMI inokukhuthaza ngempumelelo iimpendulo ezahlukeneyo zokutshintshwa kwe-nucleophilic, ezinje ngokwenziwa kwee-phenyl ether derivatives, ii-amino compounds kunye nee-fluorobenzene derivatives. I-dielectric constant yayo ephezulu kunye ne-cationic solvation inokunyusa ii-anionic nucleophilic reactions. Ezi mveliso zokwenziwa zisetyenziswa njengezinto eziphakathi zokwenziwa kwee-pesticides, amayeza, iidayi kunye nee-resin monomers ezisebenza kakuhle.

4. Iimveliso zepetroliyam

I-DMI inendawo yokubila ephezulu kunye nozinzo oluphezulu lobushushu, kwaye akulula ukwenza i-azeotropes nezinye izinto. Ke ngoko, ingasetyenziswa kwiinkqubo ezininzi zoshishino ezifana nokukhupha ulwelo-ulwelo, ukusasazwa kombane ochaseneyo, ukucocwa kombane osuswayo kunye nokuhlanjwa kombane ochaseneyo. I-DMI yi-BTX elungileyo (benzene, toluene kunye ne-xylene) extractant kuba inyibilikisa iikhompawundi ze-aromatic kunye nee-hydrocarbons ezingagcwaliyo, kodwa ayinyibilikisi iparafini.

5. Isinyibilikisi se-polymer reaction

I-DMI yeyona nto inyibilikisayo kuphela esetyenziselwa ukuvelisa ii-thermoplastics ezimelana nobushushu. Ikwasetyenziswa ngempumelelo njengesinyibilikisi kwiinkqubo ezahlukeneyo zokwenziwa kwe-polymer kunye nesepha yokupholisha kunye nokubumba iplastiki. Kwimveliso yee-polyamide kunye nee-polyimide resins, i-DMI ikhawulezisa ukwakheka kwamaqela e-amide kunye ne-imine ukuze kufunyanwe ii-polymers ezinobunzima obukhulu beemolekyuli, kwaye isisombululo esiphumayo sifanelekile ekujikelezweni kwesisombululo ukuze kufunyanwe iifayibha ze-polyimide ezimelana nobushushu obuphezulu.

Kwimveliso ye-polyphenylene sulfide resin (PPS), izixhobo ze-elektroniki ezinobungakanani obuncinci kakhulu bokungcola okuphilayo zinokufunyanwa yi-DMI. Kwimveliso ye-polyphenylene ether sulfone resin, i-DMI inokulawula ngempumelelo ukwenzeka kweempendulo ezingalindelekanga kwaye ifumane iimveliso ze-polymer ezikumgangatho ophezulu. Xa i-polyimide resin kunye ne-polysulfone resin zenziwe iifilimu kwaye iifilimu ze-polyether ketone resin zolulwa, unyango nge-DMI lunokwenza iifilimu zifane ngakumbi.

6. Isixhobo sokususa inkqubo yefotolithography

Ngenxa yokuba incinci kakhulu kwaye i-dielectric constant ephezulu, i-DMI ingasetyenziswa njengesinyibilikisi se-electrolyte kwiibhetri ze-lithium ezisebenza kakuhle. Ukongeza, inompompo onamandla, iqondo lokubila eliphezulu kunye nokumelana nobushushu obuphezulu, kwaye ingasetyenziswa njenge-stripper ye-silicon wafer photoresist. Iipropati zayo zokususa ngokukhawuleza kunye nokungaboli zenza lula kakhulu inkqubo yokususa kwaye ikhawulezise imveliso yokusika iitships.

7. Isepha yokucoca

I-DMI yongezwa kumxube wee-surfactants, ii-alkalis, ii-alcohols kunye nee-polyoxyethylene alkyl ethers ukuze kufunyanwe isepha enamandla. Ekubeni i-DMI kulula kakhulu ukuyinyibilikisa inkunkuma, ingasetyenziselwa nokulungiselela izisombululo zokucoca ezisebenzayo zokucoca iglasi kunye nesinyithi.

8. Iidayi kunye nemibala

Ii-inki ezenziwe ngokuxuba i-DMI kunye nezinto ezinyibilikisayo kwaye iidayi kunye nemibala zinokuprintwa ngokwahlukileyo, kwaye umfanekiso ucacile.

9. Iarhente yonyango lomphezulu

I-DMI ingasetyenziswa njengearhente yonyango lomphezulu ukuphucula amandla okubopha e-ABS, i-polyimide, i-PPS, i-Teflon kunye nezinye izinto ezine-epoxy resin adhesives.
