Mawu Oyamba
1,1-dibromo-3,3,3-trifluoroacetone ndi organic pawiri ndi mankhwala chilinganizo C3Br2F3O. Zotsatirazi ndizofotokozera za katundu, ntchito, kukonzekera ndi chitetezo cha pawiri:
Chilengedwe:
-Maonekedwe: 1,1-dibromo-3,3,3-trifluoroacetone ndi madzi achikasu owala kapena olimba.
-Kuchulukana: 1.98g/cm³
-malo osungunuka: 44-45 ℃
- Malo otentha: 96-98 ℃
-Kusungunuka: Kusungunuka m'madzi, ethanol ndi ether.
Gwiritsani ntchito:
- 1,1-dibromo-3,3,3-trifluoroacetone imagwiritsidwa ntchito makamaka ngati organic synthesis reagent ndipo ingagwiritsidwe ntchito pokonzekera mankhwala ena.
-Pawiriyi itha kugwiritsidwanso ntchito ngati chothandizira, chowongolera, komanso pama labotale kuti adziwe ma microwave mita.
Njira Yokonzekera:
1,1-dibromo-3,3,3-trifluoroacetone ikhoza kukonzedwa ndi izi:
1. Choyamba, acetone imakhudzidwa ndi bromine trifluoride kupanga 3,3, 3-trifluoroacetone.
2. Kenaka, pamikhalidwe yoyenera, 3,3,3-trifluoroacetone imachitidwa ndi bromine kuti apange 1,1-dibromo-3,3,3-trifluoroacetone.
Zambiri Zachitetezo:
1,1-dibromo-3,3,3-trifluoroacetone ndi organic bromine pawiri ndi kawopsedwe zina ndi corrosiveness. Samalani zinthu zotsatirazi zotetezedwa mukamagwiritsa ntchito:
- Pewani kukhudzana mwachindunji ndi khungu ndi maso, valani magolovesi oteteza, magalasi oteteza komanso chophimba kumaso ngati kuli kofunikira.
- Gwiritsani ntchito polowera mpweya kuti musapume mpweya kapena nthunzi.
-Pewani kukhudzana ndi ma oxidants ndi zoyaka moto panthawi yosungira, ndikuziyika mu chidebe chotsekedwa, kutali ndi magwero a moto ndi malo otentha kwambiri.
-Pewani zokhala ndi magetsi osasunthika mukamagwiritsa ntchito kuteteza moto kapena kuphulika.
Chonde dziwani kuti 1,1-dibromo-3,3,3-trifluoroacetone ndi akatswiri a labotale reagent, omwe angagwiritsidwe ntchito ndi akatswiri pamikhalidwe yoyenera ndipo sayenera kugwiritsidwa ntchito kapena kusamaliridwa mwakufuna kwake.
