Koj paub ntau npaum li cas txog Benzotrifluoride (CAS: 98-08-8)

Chemical Property:Benzotrifluoride (CAS: 98-08-8) zoo li cov kua tsis muaj xim nrog cov ntxhiab tsw.Insoluble hauv dej, soluble hauv ethanol, ether, acetone, benzene, carbon tetrachloride, thiab lwm yam.

Tus nqi:Benzotrifluoride (CAS: 98-08-8) tuaj yeem siv los ua ib qho nruab nrab hauv cov organic synthesis, dyes, pharmaceuticals, vulcanizing agents, accelerators, thiab hauv kev tsim cov roj insulating.Nws tuaj yeem siv los txiav txim siab tus nqi calorific ntawm cov roj, npaj cov hmoov hluav taws tua hluav taws, thiab tseem ua cov khoom ntxiv rau cov yas photodegradable.Benzotrifluoride yog ib qho tseem ceeb hauv nruab nrab ntawm fluorine chemistry, uas tuaj yeem siv los npaj cov tshuaj tua kab xws li fluchlor, fluorochlor, thiab pyrfluchlor, thiab tseem yog ib qho tseem ceeb nruab nrab ntawm cov tshuaj.

Ntau lawmMethod:1. Benzotrifluoride yog npaj los ntawm ω,ω,ω- Benzotrifluoride yog tau los ntawm reacting nrog anhydrous hydrogen fluoride.ω,ω,ω- Cov molar 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 siab ntawm 1.67-1.77 MPa.Cov txiaj ntsig yog 72.1%.Vim qhov pheej yig thiab yooj yim muaj ntawm cov dej tsis muaj hydrogen fluoride, cov cuab yeej siv tau yooj yim, tsis xav tau cov hlau tshwj xeeb, tus nqi qis, thiab tsim nyog rau industrialization.2. Los ntawm ω,ω,ω Chemicalbook-Benzotrifluoride yog tau los ntawm reacting nrog antimony Benzotrifluoride.noj ωωω Benzotrifluoride thiab antimony Benzotrifluoride yog rhuab thiab distilled nyob rau hauv ib lub lauj kaub tshuaj tiv thaiv, thiab cov distillate yog crude trifluoromethylbenzene.Ntxuav nrog 5% hydrochloric acid, ntxiv 5% sodium hydroxide tov, cua sov thiab distilled, thiab sau cov feem ntawm 80-105 ℃.Cais cov kua dej sab saud, qhuav cov kua qis nrog cov calcium chloride anhydrous, thiab lim kom tau txais trifluoromethylbenzene.Cov txiaj ntsig yog 75%.Txoj kev no siv cov tshuaj tiv thaiv antimony thiab muaj tus nqi siab, uas feem ntau yooj yim dua los siv tsuas yog nyob rau hauv chav kuaj mob.

Kev npaj:Benzotrifluoride (CAS: 98-08-8) yog cov organic nruab nrab uas tuaj yeem tau txais los ntawm chlorination thiab fluorination ntawm toluene.

Kev khaws cia thiab kev thauj mus los yam ntxwv:warehouse cua cua, cua kub kom qhuav;Khaws cais ntawm oxidants thiab acids
