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

1.1,3-Dimethyl-2-imidazolidinone yog siv los kawm txog cov khoom siv hloov pauv hydrosilane dibasic uas ruaj khov los ntawm kev tsim cov duab ntawm aryl silanes.

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

3. Cov tshuaj tiv thaiv

Vim nws qhov kev ruaj khov zoo heev ntawm thermal thiab tshuaj lom neeg, DMI muaj solubility hauv inorganic, organic compounds thiab ntau yam resins, thiab nws cov nyhuv catalytic ua cov tshuaj solvent tsis-protonic polar ua rau nws yog cov tshuaj tiv thaiv zoo tshwj xeeb. . Siv DMI, cov txiaj ntsig tuaj yeem txhim kho thiab cov tshuaj tiv thaiv sab nraud tuaj yeem tswj tau zoo thaum lub sijhawm luv luv.

DMI tuaj yeem txhawb nqa ntau yam kev hloov pauv nucleophilic, xws li kev tsim cov phenyl ether derivatives, amino compounds thiab fluorobenzene derivatives. Nws cov dielectric tas mus li thiab cationic solvation tuaj yeem ua rau cov tshuaj anionic nucleophilic reactions. Cov khoom siv hluavtaws no yog siv ua cov khoom siv nruab nrab rau kev tsim cov tshuaj tua kab, tshuaj, dyes thiab cov khoom siv ua tau zoo.

4. Cov khoom siv roj av

DMI muaj lub ntsiab lus kub siab thiab kev ruaj khov thermal siab, thiab tsis yooj yim rau kev tsim cov azeotropes nrog lwm yam tshuaj. Yog li ntawd, nws tuaj yeem siv rau hauv ntau cov txheej txheem kev lag luam xws li kua-kua rho tawm, kev faib tawm tam sim no, kev rho tawm thiab kev ntxuav tam sim no. DMI yog ib qho zoo BTX (benzene, toluene thiab xylene) extractant vim nws yaj cov tshuaj aromatic thiab cov hydrocarbons unsaturated, tab sis tsis yaj paraffin.

5. Cov tshuaj tiv thaiv polymer

DMI yog tib cov kuab tshuaj uas siv los tsim cov thermoplastics uas tiv taus cua sov. Nws kuj tseem siv tau zoo ua cov kuab tshuaj rau ntau yam txheej txheem tsim cov polymer thiab cov tshuaj ntxuav rau polymerization thiab yas molding. Hauv kev tsim cov polyamide thiab polyimide resins, DMI ua kom cov amide thiab imine pawg sai dua kom tau txais cov polymers hnyav molecular siab, thiab cov kua tsim tau zoo rau kev sib hloov cov kua kom tau txais cov polyimide fibers uas tiv taus kub siab.

Hauv kev tsim cov polyphenylene sulfide resin (PPS), cov khoom siv hluav taws xob nrog cov khoom me me ntawm cov organic impurities tuaj yeem tau txais los ntawm DMI. Hauv kev tsim cov polyphenylene ether sulfone resin, DMI tuaj yeem tswj tau qhov tshwm sim ntawm cov tshuaj tiv thaiv sab nraud thiab tau txais cov khoom polymer zoo. Thaum polyimide resin thiab polysulfone resin raug tsim ua cov yeeb yaj kiab thiab polyether ketone resin zaj duab xis raug ncab, kev kho nrog DMI tuaj yeem ua rau cov yeeb yaj kiab sib xws dua.

6. Cov txheej txheem photolithography stripper

Vim nws cov viscosity qis thiab dielectric constant siab, DMI tuaj yeem siv ua electrolyte solvent rau cov roj teeb lithium ua haujlwm siab. Tsis tas li ntawd, nws muaj permeability muaj zog, boiling point siab thiab kub tsis kam, thiab kuj tuaj yeem siv ua stripper rau silicon wafer photoresist. Nws cov khoom stripping ceev thiab tsis xeb ua rau cov txheej txheem stripping yooj yim dua thiab ua kom cov khoom tsim tau sai dua.

7. Tshuaj ntxuav khaub ncaws

DMI raug ntxiv rau hauv cov tshuaj surfactants, alkalis, alcohols thiab polyoxyethylene alkyl ethers kom tau ib lub tshuaj ntxuav muaj zog. Vim tias DMI yooj yim heev rau yaj cov av, nws kuj siv tau los npaj cov tshuaj ntxuav zoo rau kev ntxuav iav thiab hlau.

8. Cov xim thiab cov xim pleev xim

Cov kua mem uas ua los ntawm kev sib xyaw DMI nrog cov khoom siv yaj thiab cov xim thiab cov xim tuaj yeem luam tawm sib piv, thiab daim duab meej.

9. Tus neeg sawv cev kho qhov chaw

DMI siv tau ua tus neeg sawv cev kho qhov chaw kom txhim kho lub zog ntawm ABS, polyimide, PPS, Teflon thiab lwm yam ntaub ntawv nrog epoxy resin adhesives.
