3-Bromo-2-chlorobenzotrifluoride (CAS# 56131-47-6)
Matšoao a Kotsi | Xi - Ea halefisang |
Likhoutu tsa Kotsi | R20/21/22 – E kotsi ka ho hema, ho kopana le letlalo le ha e koetsoe. R36/37/38 – Ho tena mahlo, tsamaiso ya ho hema le letlalo. |
Tlhaloso ea Tšireletseho | S26 - Ha u kopana le mahlo, hlatsoa hang-hang ka metsi a mangata 'me u batle keletso ea bongaka. S36 - Apara liaparo tse loketseng tsa tšireletso. |
Tsebiso ea Kotsi | E tenang |
Selelekela
Ke motsoako oa tlhaho o nang le foromo C7H3BrClF3. E latelang ke tlhaloso ea thepa, tšebeliso, tokiso le tlhaiso-leseling ea polokeho ea komporo:
Tlhaho:
-Ponahalo: mokelikeli o se nang 'mala
- Sebaka sa ho qhibiliha: -14°C
- Sebaka se belang: 162°C
- Boima: 1.81g/cm³
-Soluble: E qhibiliha ka har'a metsoako ea tlhaho e kang ether le dichloromethane, e qhibilihang hanyane ka metsing.
Sebelisa:
-e sebelisoa haholo e le setsi sa lipakeng tsa organic synthesis, haholo-holo masimong a meriana le chefo e bolaeang likokoanyana.
-E ka boela ea sebelisoa e le mokhoa o rarahaneng oa synthesis ea asymmetric, li-catalysts le likristale tsa metsi.
Mokhoa oa ho itokisa:
Synthesized ka karabelo e latelang:
1. Ntlha ea pele, 2-chlorotrifluorotoluene (C7H4ClF3) e itšoara ka sodium nitrite-N-acetamide e rarahaneng ho fumana 2-nitrotrifluorotoluene (C7H3NO2F3).
2. 2-Nitrotrifluorotoluene e sebetsana le hydrogen bromide, 'me joale sehlopha se sebetsang sa nitro se nkeloa sebaka ke sehlopha sa bromine se sebetsang ka mokhoa oa ho fetola ho fumana sehlopha se sebetsang sa nitro.
Lintlha tsa Tšireletseho:
-e tlameha ho ba motsoako oa manyolo, o nang le ts'usumetso e itseng le chefo. Ka kopo ela hloko ts'ebetso e nepahetseng le polokelo.
- Tšebeliso e lokela ho roala liatlana tse sireletsang, likhalase le limaske tse sireletsang ho qoba ho kopana le letlalo le ho hema khase.
- Qoba ho kopana le li-oxidants tse matla, li-acid tse matla, li-alkali tse matla le mehloli ea mollo ho thibela liketso tse kotsi.
-Sebetsa sebakeng se nang le moea o motle, hole le mehloli ea mollo le mocheso.
-Ha motho a ka kopana kapa a ja, batla thuso ea bongaka hang-hang.
