| Whakaahuatanga Haumaru | S53 – A ape i te rongo – whiwhi tohutohu motuhake i mua i te whakamahi. S26 – Mena ka pa ki nga kanohi, horoi tonu ki te nui o te wai me te rapu tohutohu hauora. S36/37 – Mau kakahu whakamarumaru me nga karapu tika. S45 – Ki te puta he aitua, ki te kore ranei koe e pai, rapu wawe i nga tohutohu hauora (whakaatuhia te tapanga ina taea.) S62 – Ki te horomia, kaua e whakaruaki; rapu wawe i nga tohutohu hauora me te whakaatu i tenei ipu, tapanga ranei. S61 – A ape i te tuku ki te taiao. Tirohia nga tohutohu motuhake / pepa raraunga haumaru. S23 – Kaua e hau kohu. S16 – Kia matara atu i nga puna o te mura. |

Nga korero
| whakarite | Ko te toluene trifluoride he takawaenga pararopi, ka taea te tiki mai i te toluene hei rauemi mata ma te whakamaarama, katahi ka whakamaarama. I te taahiraa tuatahi, i konatunatuahia te maota, te toluene me te whakakorikori hei tauhohenga maaota; Ko te 60 ℃ te pāmahana tauhohenga mātao me te pēhanga tauhohenga he 2Mpa; I te taahiraa tuarua, ka tapirihia te hauwai pukoro me te whakakōkī ki te ranunga pākawa i te taahiraa tuatahi mo te tauhohenga fluorination; Ko te pāmahana tauhohenga fluorination he 60 ℃ me te pēhanga tauhohenga he 2MPa; I te toru o nga taahiraa, ko te ranunga i muri i te rua o nga tauhohenga fluorination i tukuna ki te maimoatanga whakatikatika kia whiwhi trifluorotoluene. |
| whakamahi | whakamahia: mo te hanga raau taero, waikano, ka whakamahia hei rongoa rongoa, pesticides, aha atu. trifluoromethylbenzene he takawaenga nui i roto i te matū fluorine, ka taea te whakamahi ki te whakarite i nga patu patupatu pera i te fluuron, fluralone, me te pyrifluramine. He takawaenga nui ano mo te rongoa. takawaenga o te rongoa me te waikano, whakarewa. A ka whakamahia hei kaihoko rongoa me te hanga hinu whakaahuru. nga takawaenga mo te whakahiato me te waikano pararopi, te raau taero, te rongoa rongoa, te whakatere, me te hanga hinu whakaahuru. Ka taea te whakamahi mo te whakatau i te uara calorific o te wahie, te whakarite i te paura o te kaipatu ahi, me te taapiri kirihou photodegradable. |
| tikanga whakaputa | 1. I ahu mai i te pahekoheko o te ω,ω,ω-trichlorotoluene me te hauwai pūkōwhai. Ko te ōwehenga molar o ω,ω,ω-trichlorotoluene ki te hauwai pūkōwhai anhydrous he 1:3.88, ka mahia te tauhohenga i te pāmahana o te 80-104 ° C. I raro i te pehanga 1.67-1.77MPA mo te 2-3 haora. Ko te hua ko te 72.1%. Na te mea he iti, he ngawari hoki te tiki i nga taputapu, kaore he maitai motuhake, he iti te utu, he pai mo te ahumahi. I ahu mai i te taunekeneke o te ω,ω,ω-toluene trifluoride me te antimony trifluoride. Ko te ω ω ω trifluorotoluene me te antimony trifluoride ka whakamahanahia, ka whakamarohia ki roto i te kohua tauhohenga, a ko te distillate he trifluoromethylbenzene maoa. I horoia te ranunga ki te 5% waikawa pūhaumāota, whai muri i te 5% konutai waihā wairewa, ka whakamahana mo te whakamahana kia kohia te hautanga 80-105 °c. I wehea te wai paparanga o runga, ka whakamarokehia te wai paparanga o raro ki te konupūmā pūhaumāota anhydrous ka tātarihia kia whiwhi trifluoromethylbenzene. Ko te hua ko te 75%. Ko tenei tikanga ka pau te antimonide, he nui ake te utu, ko te tikanga anake i roto i nga tikanga taiwhanga e whakamahi ana i te watea ake. Ko te tikanga whakarite ko te whakamahi i te toluene hei rauemi mata, katahi ka whakamahia te hau maataa i te aroaro o te whakakorikori o te mekameka taha ki te whiwhi α,α,α-trichlorotoluene, katahi ka tauhohe ki te hauwai fluoride ki te whiwhi i te hua. |
