Cov Khoom Siv Tshuaj:Benzotrifluoride (CAS: 98-08-8) zoo li kua tsis muaj xim nrog lub ntxhiab tsw qab. Insoluble hauv dej, soluble hauv ethanol, ether, acetone, benzene, carbon tetrachloride, thiab lwm yam.
Tus nqi:Benzotrifluoride (CAS: 98-08-8) siv tau ua ib qho nruab nrab hauv kev tsim cov organic, cov xim, cov tshuaj, cov neeg sawv cev vulcanizing, cov khoom ua kom nrawm, thiab hauv kev tsim cov roj rwb thaiv tsev. Nws siv tau rau kev txiav txim siab qhov calorific nqi ntawm cov roj, npaj cov hmoov tua hluav taws, thiab tseem ua haujlwm ua cov khoom ntxiv rau cov yas photodegradable. Benzotrifluoride yog ib qho nruab nrab tseem ceeb hauv fluorine chemistry, uas siv tau los npaj cov tshuaj tua kab xws li fluchlor, fluorochlor, thiab pyrfluchlor, thiab kuj yog ib qho nruab nrab tseem ceeb hauv kev kho mob.
Kev tsim khoomMtxoj kev:1. Benzotrifluoride yog npaj los ntawm ω, ω, ω- Benzotrifluoride yog tau los ntawm kev cuam tshuam nrog anhydrous hydrogen fluoride. ω, ω, ω- Qhov piv ntawm Benzotrifluoride rau anhydrous hydrogen fluoride yog 1: 3.88. Cov tshuaj tiv thaiv tshwm sim rau 2-3 teev ntawm qhov kub ntawm 80-104 ℃ thiab qhov siab ntawm 1.67-1.77 MPa. Cov txiaj ntsig yog 72.1%. Vim tias pheej yig thiab yooj yim muaj anhydrous hydrogen fluoride, cov khoom siv yooj yim, tsis tas yuav siv cov hlau tshwj xeeb, tus nqi qis, thiab tsim nyog rau kev lag luam. 2. Los ntawm ω, ω, ω Phau Ntawv Tshuaj - Benzotrifluoride yog tau los ntawm kev cuam tshuam nrog antimony Benzotrifluoride. noj ωωω Benzotrifluoride thiab antimony Benzotrifluoride raug cua sov thiab distilled hauv lub lauj kaub tshuaj tiv thaiv, thiab cov distillate yog cov roj trifluoromethylbenzene nyoos. Ntxuav nrog 5% hydrochloric acid, ntxiv 5% sodium hydroxide kua, cua sov thiab distill, thiab sau cov feem ntawm 80-105 ℃. Cais cov kua sab saud, ziab cov kua sab hauv qab nrog anhydrous calcium chloride, thiab lim kom tau trifluoromethylbenzene. Cov txiaj ntsig yog 75%. Txoj kev no siv cov tshuaj antimony thiab muaj tus nqi siab, uas feem ntau yooj yim dua rau siv tsuas yog nyob rau hauv cov xwm txheej hauv chaw kuaj mob.
Kev Npaj:Benzotrifluoride (CAS: 98-08-8) yog ib qho organic intermediate uas tuaj yeem tau los ntawm chlorination thiab fluorination ntawm toluene.
Cov yam ntxwv ntawm kev khaws cia thiab kev thauj mus los:Qhov cua hauv tsev rau khoom, ziab kom qhuav hauv qhov kub qis; Khaws cia cais ntawm cov oxidants thiab cov kua qaub
