| Inqaku Lengozi | Iyacaphukisa |
Intshayelelo
Yikhompawundi ephilayo enefomula C7H3BrClF3. Oku kulandelayo yinkcazo yeepropati, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko lwekhompawundi:
Indalo:
-Imbonakalo: ulwelo olungenambala
-Indawo yokunyibilika:-14°C
-Indawo yokubila: 162°C
-Ubuninzi: 1.81g/cm³
-Inyibilikayo: Inyibilika kwizinyibilikisi zendalo ezifana ne-ether kunye ne-dichloromethane, zinyibilika kancinane emanzini
Sebenzisa:
-isetyenziswa ngokubanzi njengendawo ephakathi kwi-organic synthesis, ngakumbi kwimimandla yamachiza kunye ne-pesticide.
-Inokusetyenziswa kwakhona njengento eyinkimbinkimbi kwi-asymmetric synthesis, i-catalysts kunye neekristali zamanzi.
Indlela yokulungiselela:
Idityaniswe ngokusabela kulandelayo:
1. Okokuqala, i-2-chlorotrifluorotoluene (C7H4ClF3) iphendulwa nge-sodium nitrite-N-acetamide eyinkimbinkimbi ukufumana i-2-nitrotrifluorotoluene (C7H3NO2F3).
2. I-2-Nitrotrifluorotoluene isabela nge-hydrogen bromide, kwaye ke iqela elisebenzayo le-nitro litshintshwa kunye neqela elisebenzayo le-bromine ngokuphendula ukutshintshwa ukuze ufumane iqela elisebenzayo le-nitro.
Ulwazi ngoKhuseleko:
-kufuneka ibe yi-organic compound, ene-sensitization ethile kunye ne-toxicity. Nceda uqaphele ukusebenza ngokuchanekileyo kunye nokugcinwa.
-Sebenzisa kufuneka banxibe iiglavu zokukhusela, izibuko kunye neemaski zokukhusela ukuphepha ukudibanisa nesikhumba kunye nokuphefumla igesi.
-Kuphephe ukudibana nee-oxidants ezinamandla, i-acids eqinile, i-alkali enamandla kunye nemithombo yomlilo ukukhusela ukuphendula okuyingozi.
-Sebenza kwindawo engenamoya, kude nomlilo kunye nemithombo yobushushu.
-Kwimeko yoqhagamshelwano okanye ukungeniswa, khangela unyango ngokukhawuleza.
