Amakuru

kwitegura	toluene trifluoride nigihe kama kama, gishobora kuboneka muri toluene nkibikoresho fatizo na chlorine hanyuma fluorination. Mu ntambwe yambere, chlorine, toluene na catalizator byavanze kugirango reaction ya chlorine; Ubushyuhe bwa chlorination bwari 60 ℃ naho umuvuduko wa reaction wari 2Mpa; Mu ntambwe ya kabiri, fluoride hydrogène na catalizator byongewe kumvange ya nitrate mu ntambwe yambere ya fluor reaction; Ubushyuhe bwa fluor bwari 60 ℃ naho umuvuduko wa reaction wari 2MPa; Mu ntambwe ya gatatu, imvange nyuma ya fluor ya kabiri yakorewe imiti ikosorwa kugirango ibone trifluorotoluene.
ikoresha	ikoresha: mugukora ibiyobyabwenge, amarangi, kandi bikoreshwa nkumuti ukiza, imiti yica udukoko, nibindi. trifluoromethylbenzene ni intera ikomeye muri chimie ya fluor, ishobora gukoreshwa mugutegura ibyatsi nka fluuron, fluralone, na pyrifluramine. Nibindi byingenzi hagati yubuvuzi. hagati yubuvuzi n irangi, solvent. Kandi ikoreshwa nkibikoresho byo gukiza no gukora amavuta yo kubika. umuhuza wa synthesis organique hamwe n amarangi, ibiyobyabwenge, imiti ikiza, yihuta, hamwe nogukora amavuta yiziritse. Irashobora gukoreshwa muguhitamo agaciro ka kalorifike ya lisansi, gutegura ibikoresho bizimya umuriro wifu, hamwe ninyongera ya plastike yifotora.
uburyo bwo kubyaza umusaruro	1. Bikomoka ku mikoranire ya ω, ω, ω-trichlorotoluene na fluoride ya hydrogène ya anhydrous. Ikigereranyo cya molari ya ω, ω, ω-trichlorotoluene na fluoride ya hydrogène hydrogène ni 1: 3.88, kandi reaction ikorwa ku bushyuhe bwa 80-104 ° C. Ku gitutu cya 1.67-1.77MPA mu masaha 2-3. Umusaruro wari 72.1%. Kuberako fluoride ya hydrogène ya anhydrous ihendutse kandi yoroshye kuyibona, ibikoresho biroroshye kubikemura, nta byuma bidasanzwe, igiciro gito, kibereye inganda. Bikomoka ku mikoranire ya ω, ω, ω-toluene trifluoride na antimoni trifluoride. Ω ω ω trifluorotoluene na antimoni trifluoride irashyuha kandi ikayungurura mu nkono ya reaction, kandi distillate ni trifluoromethylbenzene. Uruvange rwogejwe hamwe na acide hydrochloric 5%, hakurikiraho 5% sodium hydroxide yumuti, hanyuma ushushe kugirango ushushe kugirango ukusanye agace ka 80-105 ° c. Amazi yo hejuru yo hejuru yaratandukanijwe, hanyuma amazi yo murwego rwo hasi yumishijwe hamwe na calcium ya chloride ya anhydrous hanyuma ayungurura kugirango abone trifluoromethylbenzene. Umusaruro wari 75%. Ubu buryo bukoresha antimonide, igiciro kiri hejuru, mubisanzwe gusa muri laboratoire ukoresheje byinshi byoroshye. Uburyo bwo gutegura ni ugukoresha toluene nkibikoresho fatizo, banza ukoreshe gaze ya chlorine imbere ya catalizator kuruhande rwa chlorine kugirango ubone α, α, α-trichlorotoluene, hanyuma ukore na fluoride hydrogène kugirango ubone ibicuruzwa.
