R48/23/24/25 - I-R65 – Inobungozi: Inokubangela umonakalo emiphungeni ukuba iginyiwe R51/53 – Ityhefu kwizinto eziphila emanzini, inokubangela iziphumo ezibi zexesha elide kwindawo ehlala emanzini. R39/23/24/25 - I-R23/24/25 – Ityhefu ngokuphefumla, xa udibana nesikhumba naxa uginyiwe. R48/20/22 - R40 – Ubungqina obuncinane besiphumo somhlaza I-R38 – Iyacaphukisa ulusu I-R22 – Iyingozi xa iginyiwe
Inkcazelo yoKhuseleko	S53 – Kuphephe ukuba sesichengeni – fumana imiyalelo eyodwa phambi kokusetyenziswa. S26 – Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango. S36/37 – Nxiba iimpahla ezifanelekileyo zokukhusela kunye neeglavu. S45 - Kwimeko yengozi okanye ukuba uziva ungaphilanga, funa iingcebiso zonyango ngokukhawuleza (bonisa ileyibhile nanini na kunokwenzeka.) S62 – Ukuba iginyiwe, musa ukugabha; funa iingcebiso zonyango ngokukhawuleza kwaye ubonise esi sikhongozeli okanye ileyibhile. S61 –Kuphephe ukukhutshelwa kokusingqongileyo. Jonga kwimiyalelo ekhethekileyo / kumaphepha edatha yokhuseleko. S23 – Musa ukuphefumla umphunga. S16 – Gcina kude kwimithombo yomlilo.

Ulwazi

ukulungiselela	i-toluene trifluoride yi-organic intermediate, enokuthi ifumaneke kwi-toluene njengento ekrwada nge-chlorination kunye ne-fluorination. Kwinqanaba lokuqala, i-chlorine, i-toluene kunye ne-catalyst yaxutywa ukusabela kwe-chlorination; Ubushushu bokusabela kwe-chlorination yayingu-60 ℃ kunye noxinzelelo lwe-reaction yi-2Mpa; Kwinqanaba lesibini, i-hydrogen fluoride kunye ne-catalyst yongezwa kumxube we-nitrate kwisinyathelo sokuqala sokusabela kwe-fluorination; Ubushushu bempendulo ye-fluorination yi-60 ℃ kunye noxinzelelo lwe-reaction yi-2MPa; Kwinqanaba lesithathu, umxube emva kokuphendula okwesibini kwe-fluorination wawuphantsi konyango lokulungiswa ukuze ufumane i-trifluorotoluene.
usebenzisa	isebenzisa: ukwenza amachiza, idayi, kwaye isetyenziswe njengearhente yokunyanga, izitshabalalisi, njl. i-trifluoromethylbenzene yinto ebalulekileyo ephakathi kwi-chemistry ye-fluorine, engasetyenziselwa ukulungisa i-herbicides efana ne-fluuron, i-fluralone, kunye ne-pyrifluramine. Kwakhona kubalulekile phakathi kweyeza. eliphakathi iyeza kunye nedayi, isinyibilikisi. Kwaye isetyenziswe njenge-arhente yokunyanga kunye nokuveliswa kweoli yokukhusela. i-intermediates ye-organic synthesis kunye nedayi, iziyobisi, ii-agent zokunyanga, ii-accelerators, kunye nokuveliswa kwee-oyile ezikhuselayo. Ingasetyenziselwa ukuqinisekiswa kwexabiso le-calorific ye-fuel, ukulungiswa kwe-agent yokucima umlilo yomgubo, kunye ne-photodegradable additive yeplastiki.
indlela yokuvelisa	1. Ithathwe kwintsebenziswano ye-ω,ω,ω-trichlorrotoluene kunye ne-anhydrous hydrogen fluoride. Umlinganiselo we-molar we-ω, ω, ω-trichlorotoluene kwi-anhydrous hydrogen fluoride yi-1: 3.88, kwaye ukusabela kuqhutyelwa kwiqondo lokushisa kwe-80-104 ° C. Ngaphantsi koxinzelelo lwe-1.67-1.77MPA iiyure ezingama-2-3. Isivuno saba ngama-72.1%. Ngenxa yokuba i-anhydrous hydrogen fluoride inexabiso eliphantsi kwaye kulula ukuyifumana, izixhobo kulula ukusombulula, akukho ntsimbi ikhethekileyo, ixabiso eliphantsi, elilungele ukwenziwa kwemizi-mveliso. Ithathwe kwintsebenziswano ye-ω,ω,ω-toluene trifluoride kunye ne-antimony trifluoride. I-ω ω ω trifluorotoluene kunye ne-antimony trifluoride ziyafudunyezwa kwaye zinyibilike kwimbiza yokusabela, kwaye idistillate yi-trifluoromethylbenzene ekrwada. Umxube uhlanjwe nge-5% ye-hydrochloric acid, ilandelwa yi-5% yesisombululo se-sodium hydroxide, kwaye ifudunyezwe i-distillation ukuqokelela i-80-105 ° c iqhezu. Ulwelo oluphezulu lwahlulwa, kwaye ulwelo olusezantsi lomiswa nge-anhydrous calcium chloride kwaye lwahluzwa ukufumana i-trifluoromethylbenzene. Isivuno sasingama-75%. Le ndlela idla i-antimonide, ixabiso liphezulu, ngokubanzi kuphela kwiimeko zebhubhoratri usebenzisa ilula ngakumbi. Indlela yokulungiselela kukusebenzisa i-toluene njengento ekrwada, sebenzisa kuqala igesi yeklorin phambi kobukho be-catalyst side chain chlorination ukuze ufumane i-α, α, α-trichlorotoluene, uze uphendule nge-hydrogen fluoride ukuze ufumane imveliso.
