Information

kugadzirira	toluene trifluoride ndeye organic yepakati, inogona kuwanikwa kubva ku toluene seyakagadzirwa neklorini uyezve fluorination. Muchikamu chekutanga, chlorine, toluene uye catalyst zvakasanganiswa nokuda kweklorination reaction; Iyo chlorination reaction tembiricha yaive 60 ℃ uye iyo reaction pressure yaive 2Mpa; Muchikamu chechipiri, hydrogen fluoride uye catalyst yakawedzerwa kune nitrate musanganiswa munhanho yekutanga ye fluorination reaction; Iyo fluorination reaction tembiricha yaive 60 ℃ uye iyo reaction pressure yaive 2MPa; Muchikamu chechitatu, musanganiswa mushure mechipiri fluorination reaction yakaiswa pasi pekugadzirisa kurapwa kuti iwane trifluorotoluene.
inoshandisa	kushandiswa: kugadzira zvinodhaka, dhayi, uye kushandiswa seanorapa mumiririri, mishonga yezvipembenene, nezvimwe. trifluoromethylbenzene yakakosha yepakati mune fluorine chemistry, inogona kushandiswa kugadzira herbicides senge fluuron, fluralone, uye pyrifluramine. Iyo yakakoshawo yepakati mukurapa. chepakati chemushonga uye dhayi, solvent. Uye inoshandiswa seanorapa agent uye kugadzirwa kwemafuta anodzivirira. zvepakati zve organic synthesis uye dhayi, zvinodhaka, zvinorapa, zvinomhanyisa, uye zvekugadzira ekudzivirira mafuta. Inogona kushandiswa kugadzwa kweiyo calorific kukosha kwehuni, kugadzirira kwehupfu yekudzima moto mumiririri, uye iyo photodegradable yepurasitiki yekuwedzera.
kugadzira nzira	1. Yakatorwa kubva mukubatana kwe ω,ω,ω-trichlorotoluene ne anhydrous hydrogen fluoride. Iyo molar ratio ye ω, ω, ω-trichlorotoluene kune anhydrous hydrogen fluoride ndeye 1: 3.88, uye mhinduro inoitwa pakupisa kwe80-104 ° C. Pasi pekumanikidzwa kwe1.67-1.77MPA kwemaawa 2-3. Goho raive 72.1%. Nekuti anhydrous hydrogen fluoride yakachipa uye iri nyore kuwana, zvishandiso zviri nyore kugadzirisa, hapana yakakosha simbi, yakaderera mutengo, yakakodzera indasitiri. Yakatorwa kubva mukudyidzana kwe ω,ω,ω-toluene trifluoride ine antimony trifluoride. Iyo ω ω ω trifluorotoluene uye antimony trifluoride zvinodziiswa nekunyungudutswa mupoto inopindura, uye distillate is crude trifluoromethylbenzene. Musanganiswa wacho wakagezwa ne5% hydrochloric acid, uchiteverwa ne5% sodium hydroxide solution, uye wakadziiswa kuitira distillation kuti utore chikamu che80-105 °c. Mushonga wepamusoro wemvura wakaparadzaniswa, uye mvura yepasi yakaomeswa neanhydrous calcium chloride uye yakasefa kuti iwane trifluoromethylbenzene. Goho raive 75%. Iyi nzira inoshandisa antimonide, mutengo wakakwira, kazhinji chete mumamiriro erabhoritari uchishandisa zviri nyore. Iyo nzira yekugadzirira ndeye kushandisa toluene seyakagadzirwa, tanga shandisa chlorine gasi pamberi pecatalyst side chain chlorination kuti uwane α, α, α-trichlorotoluene, uye wozoita nehydrogen fluoride kuti uwane chigadzirwa.
