Taw qhia
Trifluoromethoxybenzene yog ib qho organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm trifluoromethoxybenzene:
Zoo:
Cov tsos mob: Trifluoromethoxybenzene yog cov kua tsis muaj xim.
Qhov ceev: 1.388 g / cm³
Solubility: Soluble nyob rau hauv cov organic solvents xws li ether thiab chloroform.
Siv:
Raws li cov kuab tshuaj: Trifluoromethoxybenzene tau dav siv los ua cov kuab tshuaj hauv thaj chaw ntawm cov organic synthesis, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj tiv thaiv hlau-catalyzed thiab aryl hnyav-catalyzed cov tshuaj tiv thaiv hauv cov organic synthesis.
Txoj kev:
Txoj kev npaj ntawm trifluoromethoxybenzene feem ntau suav nrog cov kauj ruam hauv qab no:
Bromomethylbenzene yog reacted nrog trifluoroformic anhydride los tsim methyl trifluoroformic acid.
Methyl trifluorostearate yog reacted nrog phenyl cawv los tsim methyl trifluorostearate phenyl cawv ether.
Methyl trifluoromethyrate stearate yog reacted nrog hydrofluoric acid los tsim trifluoromethoxybenzene.
Cov ntaub ntawv kev nyab xeeb:
Trifluoromethoxybenzene yog khaus thiab flammable, thiab yuav tsum tsis txhob sib cuag nrog cov tawv nqaij thiab qhov muag, kom deb ntawm qhov qhib nplaim taws thiab kub.
Haus dej kom txaus thaum siv; Siv cov cuab yeej tiv thaiv tus kheej xws li hnab looj tes tshuaj, tsom iav, thiab hnav ris tsho.
Thaum khaws cia thiab tuav, cov txheej txheem kev nyab xeeb tshuaj yuav tsum tau ua raws thiab khaws cia kom raug.
