Isakhiwo Samakhemikhali:I-Benzotrifluoride(CAS:98-08-8) ibonakala njengoketshezi olungenambala olunephunga elimnandi.Ayincibiliki emanzini, ayincibiliki ku-ethanol, ether, acetone, benzene, carbon tetrachloride, njll.
Inani:I-Benzotrifluoride(CAS:98-08-8) ingasetshenziswa njengendawo ephakathi ku-organic synthesis, odayi, imithi, ama-vulcanizing ejenti, ama-accelerator, kanye nasekwakheni amafutha avikelayo.Ingasetshenziselwa ukunquma inani le-calorific lamafutha, ukulungiselela i-powder fire extinguishing agents, futhi iphinde isebenze njengezithasiselo zamapulasitiki angakwazi ukubola.I-Benzotrifluoride iyingxenye ebalulekile ye-fluorine chemistry, engasetshenziswa ukulungisa imithi yokubulala ukhula njenge-fluchlor, i-fluorochlor, kanye i-pyrfluchlor, futhi iyingxenye ebalulekile yezokwelapha.
UkukhiqizaMindlela:1. I-Benzotrifluoride ilungiswa kusuka ku-ω,ω,ω- I-Benzotrifluoride itholakala ngokusabela nge-anhydrous hydrogen fluoride.ω,ω,ω- Isilinganiso semola ye-Benzotrifluoride ne-anhydrous hydrogen fluoride ngu-1:3.88.Ukusabela kwenzeka amahora angu-2-3 ekushiseni kuka-80-104 ℃ kanye nengcindezi ye-1.67-1.77 MPa.Isivuno saba ngu-72.1%.Ngenxa yokushibhile nokutholakala kalula kwe-anhydrous hydrogen fluoride, isixazululo semishini esilula, asikho isidingo sensimbi ekhethekile, izindleko eziphansi, futhi ezifanele ukwenziwa kwezimboni.2. Ngo-ω,ω,ω Chemicalbook-Benzotrifluoride itholakala ngokusabela nge-antimony Benzotrifluoride.thatha i-ωωω Benzotrifluoride ne-antimony I-Benzotrifluoride iyashiswa futhi igaywe ebhodweni lokusabela, futhi i-distillate i-trifluoromethylbenzene engahluziwe.Geza ngo-5% we-hydrochloric acid, engeza isixazululo se-sodium hydroxide engu-5%, ukushisa kanye ne-distill, bese uqoqa ingxenyenamba ku-80-105 ℃.Hlukanisa uketshezi olungaphezulu, yomisa uketshezi olungezansi nge-anhydrous calcium chloride, bese ukuhlunga ukuze uthole i-trifluoromethylbenzene.Isivuno singama-75%.Le ndlela idla izinhlanganisela ze-antimony futhi inezindleko eziphezulu, ngokuvamile ezisebenziseka kalula ngaphansi kwezimo zaselabhorethri.
Ukulungiselela:I-Benzotrifluoride(CAS:98-08-8) iwumzimba ophakathi nendawo ongatholwa nge-chlorination kanye ne-fluorination ye-toluene.
Isitoreji nezici zokuthutha:ukungenisa umoya endaweni yokugcina impahla, ukomisa izinga lokushisa eliphansi;Gcina ngokwehlukana nama-oxidants nama-asidi
