Zambiri

kukonzekera	toluene trifluoride ndi organic wapakatikati, amene angapezeke kuchokera toluene monga zopangira ndi chlorination ndiyeno fluorination. Mu sitepe yoyamba, klorini, toluene ndi chothandizira zinasakanizidwa ndi chlorination reaction; The chlorination anachita kutentha anali 60 ℃ ndi kuthamanga anachita anali 2Mpa; Mu sitepe yachiwiri, haidrojeni fluoride ndi chothandizira anawonjezera kwa nitrate osakaniza mu sitepe yoyamba kwa fluorination anachita; The fluorination anachita kutentha anali 60 ℃ ndi kuthamanga anachita anali 2MPa; Mu sitepe yachitatu, osakaniza pambuyo yachiwiri fluorination anachita anali pansi rectification mankhwala kupeza trifluorotoluene.
amagwiritsa	ntchito: kupanga mankhwala, utoto, ndi ntchito ngati machiritso wothandizira, mankhwala ophera tizilombo, etc. trifluoromethylbenzene ndi yofunika yapakatikati mu chemistry ya fluorine, yomwe ingagwiritsidwe ntchito pokonzekera mankhwala ophera udzu monga fluuron, fluralone, ndi pyrifluramine. Ndiwofunikanso pakati pa zamankhwala. wapakati mankhwala ndi utoto, zosungunulira. Ndipo amagwiritsidwa ntchito ngati machiritso komanso kupanga mafuta oteteza. zopangira ma organic synthesis ndi utoto, mankhwala, machiritso, ma accelerator, komanso kupanga mafuta oteteza. Itha kugwiritsidwa ntchito pozindikira kuchuluka kwamafuta amafuta, kukonza zozimitsa moto wa ufa, ndi chowonjezera cha pulasitiki chowonongeka.
njira yopanga	1. Kuchokera ku kugwirizana kwa ω,ω,ω-trichlorrotoluene ndi anhydrous hydrogen fluoride. Chiŵerengero cha molar cha ω, ω, ω-trichlorotoluene kwa anhydrous hydrogen fluoride ndi 1: 3.88, ndipo zomwe zimachitika pa kutentha kwa 80-104 ° C. Pansi pa 1.67-1.77MPA kwa maola 2-3. Zokolola zinali 72.1%. Chifukwa anhydrous hydrogen fluoride ndi yotsika mtengo komanso yosavuta kupeza, zidazo ndizosavuta kuthetsa, palibe chitsulo chapadera, chotsika mtengo, choyenera kupanga mafakitale. Amachokera ku kugwirizana kwa ω,ω,ω-toluene trifluoride ndi antimony trifluoride. The ω ω ω trifluorotoluene ndi antimony trifluoride amatenthedwa ndikusungunulidwa mumphika wochitira, ndipo distillate ndi crude trifluoromethylbenzene. The osakaniza anasambitsidwa ndi 5% hydrochloric acid, kenako 5% sodium hydroxide njira, ndi mkangano kwa distillation kusonkhanitsa 80-105 °c kachigawo. The chapamwamba wosanjikiza madzi analekanitsidwa, ndi m'munsi wosanjikiza madzi zouma ndi anhydrous calcium kolorayidi ndi osasankhidwa kupeza trifluoromethylbenzene. Zokolola zinali 75%. Njirayi imadya antimonide, mtengo wake ndi wokwera, nthawi zambiri m'ma labotale pogwiritsa ntchito zosavuta. Njira yokonzekera ndikugwiritsa ntchito toluene ngati zopangira, choyamba gwiritsani ntchito mpweya wa chlorine pamaso pa chothandizira mbali ya chlorination kuti mupeze α, α, α-trichlorotoluene, ndiyeno muzichita ndi hydrogen fluoride kuti mupeze mankhwala.
