Taw qhia
Methylphenyldichlorosilaneyog ib qho organosilicon compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj, thiab cov ntaub ntawv kev nyab xeeb ntawm cov khoom sib xyaw:
Zoo:
- Cov tsos mob: tsis muaj xim rau yellowish kua.
- Solubility: Soluble nyob rau hauv cov organic solvents xws li cawv, ethers thiab aromatic hydrocarbons.
- Kev ruaj ntseg: zoo li ruaj khov, tab sis tuaj yeem ua rau qeeb qeeb ntawm huab cua noo.
Siv:
- Raws li cov kuab tshuaj organosilicon: Methylphenyl dichlorosilane tuaj yeem siv los ua cov reagent thiab hnyav hauv cov organic synthesis cov tshuaj tiv thaiv, thiab muaj ntau yam kev siv hauv thaj chaw ntawm cov organic synthesis.
- Tus neeg saib xyuas kev kho deg: Nws tuaj yeem siv los ua tus neeg sawv cev kho qhov chaw hauv kev lag luam xws li cov neeg tso tawm, defoamers, thiab cov tshuaj tua dej.
- Tshuaj reagents: Methylphenyldichlorosilane yog siv los ua reagent hauv qee txoj kev tshuaj xyuas tshuaj.
Txoj kev:
Methylphenyldichlorosilane tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm toluene thiab hydrogen chloride catalyzed los ntawm sulfuric acid. Qhov sib npaug ntawm cov tshuaj tiv thaiv yog raws li nram no:
C6H5CH3 + HCl + Cl2 → C7H7Cl2Si + H2O
Cov ntaub ntawv kev nyab xeeb:
- Methylphenyldichlorosilane ua rau khaus thiab tuaj yeem ua rau khaus thiab kub hnyiab ntawm daim tawv nqaij thiab qhov muag, yog li hnav hnab looj tes tiv thaiv thiab tsom iav thaum siv nws.
- Tsis txhob nqus los yog nqus tau, thiab yog tias nqus tau, txav nrawm mus rau qhov chaw muaj cua zoo.
- Thaum khaws cia thiab siv, khaws cia rau hauv qhov chaw txias, qhuav, qhov cua zoo, kom deb ntawm hluav taws thiab cua sov.
- Cov txheej txheem ua haujlwm kom raug thiab kev ua haujlwm nyab xeeb yuav tsum tau ua raws li kev nyab xeeb ntawm tus kheej thiab kev nyab xeeb hauv chav kuaj.
