Mawu Oyamba
Ndi organic pawiri ndi mankhwala chilinganizo C7H3BrFN. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
-Mawonekedwe: Olimba akristalo opanda mtundu.
- Malo osungunuka: pafupifupi 59-61 ° C.
- Malo otentha: pafupifupi 132-133 ℃.
-Kuyamba kwa fungo: Palibe deta yodalirika.
-Kusungunuka: Kusungunuka mu zosungunulira organic monga ether, dimethylformamide ndi benzene, osasungunuka m'madzi.
Gwiritsani ntchito:
-ndi organic synthesis yapakatikati yomwe ingagwiritsidwe ntchito kupanga zinthu monga mankhwala, mankhwala ophera tizilombo ndi utoto.
-Itha kugwiritsidwa ntchito ngati reagent poyambitsa halogen muzinthu zonunkhira mu organic synthesis.
Njira Yokonzekera:
-fluorobenzonitrile ikhoza kukonzedwa powonjezera cuprous bromide (CuBr) ku 4-fluorobenzonitrile (C7H4FN).
Zambiri Zachitetezo:
-Zimakhala zokwiyitsa komanso zowononga, ndipo kukhudzana ndi khungu ndi maso kumayambitsa kuyabwa.
-Valani zida zodzitetezera zoyenera monga magalasi, magolovesi, ndi malaya a labu mukugwira ntchito.
-Pogwiritsa ntchito ndikusunga, ndikofunikira kutsatira njira zoyendetsera bwino ndikusunga bwino mu chidebe chosindikizidwa, kutali ndi poyatsira ndi oxidizing agents.
-Akauzira kapena kumeza, pita kuchipatala msanga. Ngati kukhudzana kumachitika, nthawi yomweyo tsitsani malo omwe akhudzidwawo ndi madzi ambiri ndikupempha thandizo lachipatala.
