Mawu Oyamba
2,5-Bis(trifluoromethyl)bromobenzene ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Ubwino:
- Maonekedwe: 2,5-Bis(trifluoromethyl)bromobenzene ndi madzi opanda mtundu.
- Kusungunuka: 2,5-bis(trifluoromethyl)bromobenzene imasungunuka mu zosungunulira za polar monga ethanol, dimethylformamide, ndi zina.
- Kukhazikika: Chigawochi chimakhala chokhazikika kutentha kwa chipinda, koma chiyenera kutetezedwa ku dzuwa.
Gwiritsani ntchito:
- 2,5-Bis(trifluoromethyl)bromobenzene ndi yofunika kwambiri pakati pa kaphatikizidwe ka organic ndipo nthawi zambiri imagwiritsidwa ntchito popanga organic synthesis.
- Itha kugwiritsidwa ntchito ngati zopangira zophera tizirombo, fungicides, ndi fungicides.
- Pawiriyi ingagwiritsidwenso ntchito pazinthu zamagetsi ndi mankhwala.
Njira:
Kukonzekera kwa 2,5-bis(trifluoromethyl)bromobenzene nthawi zambiri kumachitika ndi izi:
1. Kuchita kwa 2,5-diiodomethylbenzene ndi trifluoromethyl bromide mu zosungunulira za organic.
2. Mankhwala okonzedwa amapangidwa ndi crystallized, amasefedwa ndi kuuma kuti apeze mankhwala abwino.
Zambiri Zachitetezo:
- 2,5-Bis(trifluoromethyl)bromobenzene imawononga maso ndi khungu, ndipo muyenera kusamala mukamagwiritsa ntchito.
- Pogwira ndikusunga, pewani kukhudzana ndi ma oxidants ndi ma alkali amphamvu kuti mupewe zoopsa.
- Mkhalidwe wabwino wolowera mpweya uyenera kusamalidwa mukamagwiritsa ntchito.
- Zikachitika mwangozi kapena kukomoka, pitani kuchipatala mwachangu. Ngati ndi kotheka, bweretsani chikalata chachitetezo chapagulu kuti muwonetsetse dokotala wanu.
