Amakhodi Engozi	R45 – Ingabangela umdlavuza R46 - Ingabangela ukulimala kofuzo I-R11 – Ivutha Kakhulu R36/38 – Ukucasuka emehlweni nasesikhumbeni. R48/23/24/25 - R65 – Iyingozi: Ingadala umonakalo wamaphaphu uma igwinyisiwe R51/53 – Ukuba nobuthi ezintweni eziphila emanzini, kungabangela imiphumela emibi yesikhathi eside endaweni yasemanzini. R39/23/24/25 - R23/24/25 – Kunobuthi ngokuhogela, ukuthintana nesikhumba futhi uma ugwinywe. R48/20/22 - R40 – Ubufakazi obuncane bomphumela we-carcinogenic R38 – Ukucasuka esikhunjeni I-R22 – Iyingozi uma igwinywe
Incazelo Yokuphepha	S53 – Gwema ukuchayeka – thola imiyalelo ekhethekile ngaphambi kokuyisebenzisa. S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. I-S36/37 – Gqoka izingubo zokuzivikela ezifanele namagilavu. S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) I-S62 – Uma igwinyisiwe, ungabangeli ukuhlanza; funa iseluleko sezokwelapha ngokushesha futhi ubonise lesi sitsha noma ilebula. I-S61 - Gwema ukudedelwa endaweni. Bheka imiyalelo ekhethekile / amaphepha edatha okuphepha. S23 – Ungawuphefumuli umhwamuko. S16 – Zigcine kude nemithombo yokuthungela.

Ulwazi

ukulungiselela	I-toluene trifluoride iyi-organic intermediate, engatholakala ku-toluene njengento eluhlaza nge-chlorination bese kuba yi-fluorination. Esinyathelweni sokuqala, i-chlorine, i-toluene kanye ne-catalyst yaxutshwa ukusabela kwe-chlorination; Izinga lokushisa lokuphendula nge-chlorination lalingu-60 ℃ futhi ingcindezi yokusabela yayiyi-2Mpa; Esinyathelweni sesibili, i-hydrogen fluoride kanye ne-catalyst yengezwe engxubeni ye-nitrate esinyathelweni sokuqala sokusabela kwe-fluorination; Izinga lokushisa lokusabela kwe-fluorination lalingu-60 ℃ futhi ingcindezi yokusabela yayiyi-2MPa; Esinyathelweni sesithathu, ingxube ngemva kokusabela kwe-fluorination yesibili yabhekana nokwelashwa kokulungiswa ukuze kutholwe i-trifluorotoluene.
isebenzisa	ukusetshenziswa: ekwenzeni izidakamizwa, odayi, futhi kusetshenziswe njenge-ejenti yokwelapha, izibulala-zinambuzane, njll. i-trifluoromethylbenzene iyingxenye ebalulekile yekhemistri ye-fluorine, engasetshenziswa ukulungisa ama-herbicides afana ne-fluuron, i-fluralone, ne-pyrifluramine. Iphinde ibe yisizinda esibalulekile kwezokwelapha. okuphakathi kwemithi nodayi, i-solvent. Futhi isetshenziswa njenge-ejenti yokwelapha kanye nokukhiqizwa kwamafutha okuvikela. okuphakathi kwe-organic synthesis nodayi, izidakamizwa, ama-ejenti okwelapha, ama-accelerator, kanye nokwakhiwa kwamafutha avikelayo. Ingasetshenziselwa ukunquma inani le-calorific likaphethiloli, ukulungiswa kwe-ejenti yokucisha umlilo eyimpushana, kanye nesengezo sepulasitiki esinesithombe.
indlela yokukhiqiza	1. Isuselwa ekusebenzelaneni kwe-ω,ω,ω-trichlorrotoluene ne-anhydrous hydrogen fluoride. Isilinganiso se-molar se-ω, ω, ω-trichlorotoluene ku-anhydrous hydrogen fluoride yi-1: 3.88, futhi ukusabela kwenziwa ekushiseni kwe-80-104 ° C. Ngaphansi kwengcindezi ye-1.67-1.77MPA amahora angu-2-3. Isivuno saba ngu-72.1%. Ngenxa yokuthi i-anhydrous hydrogen fluoride ishibhile futhi kulula ukuyithola, okokusebenza kulula ukukuxazulula, akukho nsimbi ekhethekile, izindleko eziphansi, ezifanele ukwenziwa kwezimboni. Isuselwe ekusebenzelaneni kwe-ω,ω,ω-toluene trifluoride ne-antimony trifluoride. I-ω ω ω trifluorotoluene kanye ne-antimony trifluoride ziyashiswa futhi zigaywe ebhodweni lokusabela, futhi i-distillate iyi-trifluoromethylbenzene engahluziwe. Ingxube igezwe ngo-5% we-hydrochloric acid, kulandele isixazululo esingu-5% se-sodium hydroxide, futhi sishisiswe ukuze kukhishwe i-distillation ukuze kuqoqwe ingxenyenamba engu-80-105 °c. Uketshezi longqimba olungaphezulu lwahlukaniswa, futhi uketshezi olungaphansi longqimba lwasomiswa nge-anhydrous calcium chloride futhi lwahlungwa ukuze kutholwe i-trifluoromethylbenzene. Isivuno saba ngu-75%. Le ndlela idla i-antimonide, izindleko ziphakeme, ngokuvamile kuphela ezimweni zaselabhorethri zisebenzisa okulula kakhulu. Indlela yokulungiselela ukusebenzisa i-toluene njengento eluhlaza, qala usebenzise igesi ye-chlorine phambi kwe-catalyst side chain chlorination ukuze uthole i-α,α,α-trichlorotoluene, bese usabela nge-hydrogen fluoride ukuze uthole umkhiqizo.
