Mawu Oyamba
4-Amino-3,5-dibromobenzotrifluoride ndi organic pawiri ndi mankhwala chilinganizo C7H4Br2F3N. Zotsatirazi ndizofotokozera za chikhalidwe chake, kagwiritsidwe ntchito, kapangidwe ndi chitetezo:
Chilengedwe:
-Maonekedwe: Cholimba chopanda mtundu kapena chopepuka
-Kusungunuka: Kusungunuka mu zosungunulira za organic monga ethanol ndi dimethylformamide
-malo osungunuka: pafupifupi 115-117 ℃
- Malo otentha: pafupifupi 285 ℃
Gwiritsani ntchito:
4-Amino-3,5-dibromobenzotrifluoride ili ndi phindu linalake ndipo imagwiritsidwa ntchito motere:
-Monga wapakatikati mu kaphatikizidwe organic, angagwiritsidwe ntchito pokonzekera mankhwala ena, monga mankhwala, mankhwala ndi utoto.
-Pakafukufuku wamankhwala, atha kugwiritsidwa ntchito ngati reagenti yochotsa chitetezo.
Njira Yokonzekera:
4-Amino-3,5-dibromobenzotrifluoride nthawi zambiri imatha kukonzedwa ndi izi:
1.3,5-dibromobenzoic acid idagwiritsidwa ntchito ngati zopangira kukonza 3,5-dibromobenzoic acid ester ndi acidification reaction.
2.3,5-dibromobenzoic acid ester imapangidwa ndi nitrogen compound ku decarboxylate kupanga 3,5-dibromobenzene acetyl chloride.
3. itani 3,5-dibromobenzotrifluoromethane ndi 3,5-dibromobenzotrifluoride kupanga 4-Amino-3,5-dibromobenzotrifluoride.
4. Chopangidwa choyera chikhoza kupezeka ndi crystallization kapena njira zina zoyeretsera.
Zambiri Zachitetezo:
- 4-Amino-3,5-dibromobenzotrifluoride imayenera kutenga njira zodzitetezera panthawi yogwira ntchito ndi kusungirako kuti zisagwirizane ndi khungu ndi maso.
- komanso kupewa kutulutsa mpweya kapena kumeza.
-Valani zida zodzitetezera zoyenera monga magalavu a mankhwala, magalasi ndi zovala zodzitetezera mukamagwiritsa ntchito.
-Pakachitika ngozi kapena mwangozi, muzimutsuka nthawi yomweyo ndi madzi ndikupita kuchipatala.
-Pogwira pawiri, chonde tsatirani njira zotetezera.
