Mawu Oyamba
Ndi organic pawiri yomwe mankhwala ake ndi C8H6BrN. Zotsatirazi ndizofotokozera za chikhalidwe chake, kagwiritsidwe ntchito, kapangidwe ndi chitetezo:
Chilengedwe:
-Mawonekedwe: Makristalo opanda mtundu mpaka owala achikasu
- Malo osungunuka: 64-68 digiri Celsius
-Kutentha kwapakati: 294-296 digiri Celsius
-Kuchulukana: 1.51 g/ml
-Kusungunuka: Kusungunuka pang'ono m'madzi, kusungunuka muzosungunulira wamba monga ethanol, etha ndi benzene
Gwiritsani ntchito:
Nthawi zambiri amagwiritsidwa ntchito ngati wapakatikati mu kaphatikizidwe ka organic ndipo angagwiritsidwe ntchito pokonzekera mankhwala ena achilengedwe. Itha kugwiritsidwa ntchito popanga mankhwala, kaphatikizidwe ka mankhwala ophera tizilombo, komanso m'makampani opanga utoto ndi utoto.
Kukonzekera Njira: Kukonzekera kwa
kawirikawiri zimachitika ndi njira zotsatirazi:
1. Yankhani p-methylbenzonitrile ndi bromine pansi pamikhalidwe yoyenera kuti mupange phenol.
Zambiri Zachitetezo:
-ndi organic pawiri ndipo ayenera kusamalidwa mosamala.
-Panthawi ya opaleshoni, chisamaliro chiyenera kutengedwa kuti musakhudze khungu, maso ndi kupuma.
-Valani zida zodzitetezera zoyenera, monga magolovesi a labu ndi magalasi.
-Izigwiritsiridwa ntchito pamalo abwino mpweya wabwino komanso kupewa kutulutsa nthunzi kapena fumbi lake.
-Ngati mwakowetsedwa kapena kulowetsedwa molakwika, funsani thandizo lachipatala mwamsanga ndikuwonetsa chidebecho kapena chizindikirocho kuti muwonetsere.
Chonde dziwani kuti mankhwala aliwonse ayenera kugwiritsidwa ntchito pansi pa malo oyenera a labotale ndikutsata njira zotetezeka zogwirira ntchito.
