Impahla Yamakhemikhali:I-Benzotrifluoride (CAS:98-08-8) ivela njengoketshezi olungenambala olunephunga elimnandi. Ayincibiliki emanzini, incibilika ku-ethanol, i-ether, i-acetone, i-benzene, i-carbon tetrachloride, njll.
Inani:I-Benzotrifluoride (CAS:98-08-8) ingasetshenziswa njengesithasiselo ekuhlanganisweni kwezinto eziphilayo, udayi, imithi, izinto ezivulcaniza, izinto ezisheshisa, kanye nasekukhiqizweni kwamafutha okuvikela. Ingasetshenziswa ekunqumeni inani lama-calories lamafutha, ukulungiselela izinto zokucima umlilo eziyimpuphu, kanye nokusebenza njengezithasiselo zepulasitiki ezibolayo. I-Benzotrifluoride iyisithasiselo esibalulekile kumakhemikhali e-fluorine, esingasetshenziswa ukulungiselela izibulali-zinambuzane ezifana ne-fluchlor, i-fluorochlor, kanye ne-pyrfluchlor, futhi iyisithasiselo esibalulekile kwezokwelapha.
UkukhiqizwaMindlela yokuziphatha:1. I-Benzotrifluoride ilungiswa kusuka ku-ω,ω,ω- I-Benzotrifluoride itholakala ngokuphendula nge-hydrogen fluoride engamanzi. ω,ω,ω- Isilinganiso se-molar se-Benzotrifluoride ne-hydrogen fluoride engamanzi siyi-1:3.88. Ukusabela kwenzeka amahora angu-2-3 ekushiseni okungu-80-104 ℃ kanye nokucindezela okungu-1.67-1.77 MPa. Isivuno sasingu-72.1%. Ngenxa yokutholakala okushibhile nokulula kwe-hydrogen fluoride engamanzi, isisombululo semishini esilula, asikho isidingo sensimbi ekhethekile, izindleko eziphansi, futhi kufanelekile ezimbonini. 2. Ngo-ω,ω,ω I-Chemicalbook-Benzotrifluoride itholakala ngokuphendula nge-antimony Benzotrifluoride. thatha i-ωωω I-Benzotrifluoride kanye ne-antimony Benzotrifluoride ziyashiswa futhi zihluzwe ebhodweni lokusabela, kanti i-distillate iyi-trifluoromethylbenzene engamanzi. Geza nge-5% hydrochloric acid, engeza isixazululo se-5% sodium hydroxide, ufudumale bese uhlanza, bese uqoqa ingxenye ku-80-105 ℃. Hlukanisa uketshezi olungaphezulu, womise uketshezi olungezansi nge-anhydrous calcium chloride, bese uhlunga ukuze uthole i-trifluoromethylbenzene. Isivuno singama-75%. Le ndlela isebenzisa ama-antimony compounds futhi inezindleko eziphakeme, ngokuvamile okulula kakhulu ukuyisebenzisa kuphela ngaphansi kwezimo zelebhu.
Ukulungiselela:I-Benzotrifluoride (CAS:98-08-8) iyi-organic intermediate engatholakala ngokufaka i-chlorination kanye nokufaka i-fluorination ye-toluene.
Izici zokugcina kanye nezokuthutha:umoya endlini yokugcina impahla, ukomisa ngokushisa okuphansi; Gcina ngokwehlukana nama-oxidants nama-acid
