Taw qhia
Trifluoromethylbenzonitrile Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
Trifluoromethylbenzonitrile yog cov kua tsis muaj xim nrog cov tshuaj tsw qab. Nws yog tsawg ntom thiab insoluble hauv dej tab sis soluble hauv ntau cov kuab tshuaj organic. Nws ruaj khov ntawm chav tsev kub tab sis tuaj yeem decompose thaum raug tshav kub.
Siv:
Trifluoromethylbenzonitrile tuaj yeem siv los ua qhov nruab nrab hauv cov organic synthesis. Hauv thaj chaw ntawm cov tshuaj tua kab, nws tuaj yeem siv rau hauv kev sib txuas ntawm cov tshuaj tua kab thiab tshuaj tua kab. Nws tseem tuaj yeem siv rau hauv kev npaj cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob.
Txoj kev:
Kev npaj ntawm trifluoromethylbenzonitrile feem ntau ua tiav los ntawm kev qhia ib pawg trifluoromethyl rau hauv benzonitrile molecule hauv cov tshuaj tiv thaiv. Nws tuaj yeem muaj ntau yam kev sib xyaw tshwj xeeb, xws li cov tshuaj tiv thaiv ntawm cyano tebchaw nrog trifluoromethyl compounds, lossis trifluoromethylation cov tshuaj tiv thaiv ntawm benzonitrile.
Cov ntaub ntawv kev nyab xeeb:
Trifluoromethylbenzonitrile yog irritating thiab corrosive ntawm siab concentrations thiab tej zaum yuav ua rau khaus lossis puas rau ntawm daim tawv nqaij, ob lub qhov muag, thiab kab mob ua pa thaum sib cuag. Yuav tsum ceev faj thaum siv, xws li hnav hnab looj tes tiv thaiv thiab tsom iav. Nws tseem yuav tsum tau ua haujlwm nyob rau hauv qhov chaw zoo-ventilated kom tsis txhob nqus pa. Thaum tuav thiab khaws cia, cov txheej txheem kev nyab xeeb yuav tsum tau ua raws thiab khaws cia kom deb ntawm qhov hluav taws kub thiab cua sov. Yog tias muaj qhov xau tshwm sim, nws yuav tsum tau muab ntxuav thiab kho raws sijhawm kom tsis txhob nkag mus rau hauv cov dej thiab cov kav dej.
