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

1.1,3-Dimethyl-2-imidazolidinone yog siv los kawm functionalized hydrosilane dibasic hloov hlau complexes stabilized los ntawm photochemical tsim ntawm aryl silanes.

2. Aprotic dipolar hnyav, 1,3-dimethyl-2-imidazolidinone feem ntau yog siv los ua carcinogen HMPA hloov.

3. Cov tshuaj tiv thaiv hnyav

Vim nws zoo heev thermal thiab tshuaj stability, DMI muaj solubility nyob rau hauv inorganic, organic tebchaw thiab ntau yam resins, thiab nws catalytic nyhuv raws li ib tug non-protonic polar hnyav ua rau nws ib tug tshwj xeeb cov tshuaj tiv thaiv hnyav. . Siv DMI, cov txiaj ntsig tuaj yeem txhim kho thiab cov kev cuam tshuam sab nraud tuaj yeem tswj tau zoo thaum txo lub sijhawm cov tshuaj tiv thaiv.

DMI tuaj yeem txhawb nqa ntau yam kev hloov pauv nucleophilic, xws li kev sib txuas ntawm phenyl ether derivatives, amino compounds thiab fluorobenzene derivatives. Nws qhov siab dielectric tas li thiab cationic kev daws teeb meem tuaj yeem ua rau cov tshuaj tiv thaiv anionic nucleophilic. Cov khoom siv hluavtaws no yog siv los ua intermediates rau kev sib txuas ntawm cov tshuaj tua kab, tshuaj, dyes thiab kev ua haujlwm siab resin monomers.

4. Cov khoom siv roj av

DMI muaj qhov kub kub kub thiab siab thermal stability, thiab tsis yooj yim rau tsim azeotropes nrog rau lwm yam tshuaj. Yog li ntawd, nws tuaj yeem siv rau hauv ntau cov txheej txheem xws li kua-kua extraction, countercurrent tis, extractive distillation thiab countercurrent ntxhua. DMI yog ib qho zoo BTX (benzene, toluene thiab xylene) extractant vim nws dissolves aromatic compounds thiab unsaturated hydrocarbons, tab sis tsis yaj paraffin.

5. Polymer tshuaj tiv thaiv hnyav

DMI tsuas yog cov kuab tshuaj siv los tsim cov thermoplastics thaum tshav kub kub. Nws kuj tseem siv tau los ua cov kuab tshuaj rau ntau yam txheej txheem polymer synthesis thiab cov tshuaj ntxuav tes rau polymerization thiab yas molding. Hauv kev tsim cov polyamide thiab polyimide resins, DMI nrawm tsim cov amide thiab imine pawg kom tau siab molecular hnyav polymers, thiab cov kev daws teeb meem yog tsim nyog rau kev daws spinning kom tau txais high-temperature resistant polyimide fibers.

Hauv kev tsim cov polyphenylene sulfide resin (PPS), cov khoom siv hluav taws xob uas muaj cov organic impurities tsawg heev tuaj yeem tau txais los ntawm DMI. Hauv kev tsim cov polyphenylene ether sulfone resin, DMI tuaj yeem tswj tau qhov tshwm sim ntawm kev tawm tsam sab nraud thiab tau txais cov khoom zoo polymer. Thaum polyimide resin thiab polysulfone resin raug tsim rau hauv cov yeeb yaj kiab thiab polyether ketone resin films tau ncab, kev kho nrog DMI tuaj yeem ua rau cov yeeb yaj kiab zoo sib xws.

6. Photolithography txheej txheem stripper

Vim nws cov viscosity tsawg thiab siab dielectric tas li, DMI tuaj yeem siv los ua cov kuab tshuaj electrolyte rau cov roj teeb lithium ua haujlwm siab. Tsis tas li ntawd, nws muaj zog permeability, siab kub taw tes thiab kub tsis kam, thiab tseem tuaj yeem siv los ua ib lub stripper rau silicon wafer photoresist. Nws ceev stripping thiab tsis-corrosive zog ua kom yooj yim rau cov txheej txheem stripping thiab ua kom cov khoom tsim ntawm nti txiav.

7. Cov tshuaj ntxuav tes

DMI tau ntxiv rau kev sib xyaw ntawm surfactants, alkalis, cawv thiab polyoxyethylene alkyl ethers kom tau txais cov tshuaj ntxuav tes muaj zog. Txij li thaum DMI yog yooj yim heev rau yaj cov av, nws kuj tseem siv tau los npaj cov kev daws teeb meem zoo rau kev ntxuav iav thiab hlau.

8. Dyes thiab pigments

Inks ua los ntawm kev sib xyaw DMI nrog cov khoom hnyav thiab cov dyes thiab pigments tuaj yeem luam tawm hauv qhov sib piv, thiab cov duab pom tseeb.

9. Nto kho tus neeg saib xyuas

DMI tuaj yeem siv los ua tus neeg saib xyuas saum npoo los txhim kho lub zog sib txuas ntawm ABS, polyimide, PPS, Teflon thiab lwm yam ntaub ntawv nrog epoxy resin adhesives.
