Taw qhia
1-fluoro-4-(trifluoromethoxy) benzene, tseem hu ua 1-fluoro-4-(trifluoromethoxy) benzene, yog cov organic 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:
1-Fluoro-4-(trifluoromethoxy) benzene yog cov kua tsis muaj xim uas muaj ntxhiab tsw. Nws yog cov kua dej ruaj khov ntawm chav tsev kub thiab tsis decompose yooj yim. Nws muaj qhov ceev ntawm 1.39 g / cm³. Cov compound tuaj yeem yaj hauv cov kuab tshuaj organic xws li ether thiab chloroform.
Siv:
1-Fluoro-4-(trifluoromethoxy) benzene muaj ntau yam kev siv hauv kev lag luam tshuaj. Nws tuaj yeem siv los ua cov khoom siv tseem ceeb thiab nruab nrab hauv cov organic synthesis. Cov fluorine thiab trifluoromethoxy pawg ntawm cov compound muaj peev xwm qhia cov pab pawg tshwj xeeb rau hauv cov organic synthesis cov tshuaj tiv thaiv, ua rau cov synthesis ntawm cov organic tebchaw nrog cov haujlwm tshwj xeeb. Nws kuj tseem siv tau los ua cov kuab tshuaj thiab catalyst.
Txoj kev:
Muaj ob txoj hauv kev tseem ceeb rau kev npaj ntawm 1-fluoro-4-(trifluoromethoxy) benzene. Ib txoj hauv kev yog npaj los ntawm cov tshuaj tiv thaiv ntawm 1-nitrono-4-(trifluoromethoxy) benzene thiab thionyl fluoride. Lwm txoj kev yog tau los ntawm cov tshuaj tiv thaiv ntawm methylfluorobenzene nrog trifluoromethanol.
Cov ntaub ntawv kev nyab xeeb:
1-Fluoro-4-(trifluoromethoxy) benzene muaj toxicity tsawg tab sis tseem muaj teeb meem. Kev sib cuag nrog daim tawv nqaij, qhov muag, thiab kab mob ua pa yuav ua rau khaus. Thaum ua haujlwm, hnav cov cuab yeej tiv thaiv tsim nyog xws li tsom iav tiv thaiv, hnab looj tes thiab lub ntsej muag tiv thaiv. Nws yuav tsum tau siv nyob rau hauv qhov chaw zoo-ventilated kom tsis txhob nqus nws vapors. Yog tias cov tshuaj tau noj lossis nqus tau, nrhiav kev kho mob tam sim ntawd.
