Mawu Oyamba
ndi organic pawiri, mankhwala chilinganizo cha C7H3BrF4, maonekedwe ake ndi colorless kapena kuwala yellow madzi. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
-Kuchulukana: pafupifupi. 1.894g/cm³
-Posungunuka: pafupifupi -23°C
-Kuwira: pafupifupi 166-168 ° C
-Kusungunuka: Ndi kusungunuka mu zosungunulira wamba organic, monga ethanol, dimethylformamide ndi dichloromethane.
Gwiritsani ntchito:
Iwo makamaka ntchito m'munda wa organic kaphatikizidwe monga zopangira kwa synthesis zosiyanasiyana mankhwala ndi intermediates. Amagwiritsidwa ntchito kwambiri muzochita za fluorination ndi ma alkylation reaction. Kuphatikiza apo, itha kugwiritsidwanso ntchito pokonzekera mankhwala ophera tizilombo, zida za photoelectric ndi zinthu zina zakuthupi.
Njira Yokonzekera:
Pali njira zambiri zophatikizira phosphor, ndipo njira yodziwika bwino imapezeka ndi zomwe 4-bromo-fluorobenzene ndi mpweya wa fluorine pamaso pa chothandizira. Njira yeniyeni yokonzekera imafuna ntchito zina za labotale ndi zikhalidwe.
Zambiri Zachitetezo:
- nthawi zambiri imakhala yotetezeka pakagwiritsidwe ntchito bwino. Komabe, mankhwala aliwonse ayenera kugwiritsidwa ntchito moyenera ndikutsata njira zotetezeka.
-Valani zida zodzitetezera zoyenera monga magalavu oteteza, magalasi ndi masks oteteza mukamagwiritsa ntchito.
-Pewani kupuma mpweya wake kapena kukhudza khungu ndi maso.
-Panthawi yosungira ndi kusamalira, pewani kukhudzana ndi ma oxidants amphamvu komanso kutentha kwambiri.
-Mukakumana mwangozi kapena mutagwiritsa ntchito molakwika, pitani kuchipatala msanga.
