Mawu Oyamba
4-Chloro-3-fluorobenzoic acid.
Katundu: Ikhoza kusungunuka mu zosungunulira zambiri za organic monga ethanol, etha ndi chloroform kutentha kwapakati.
Ntchito: Itha kugwiritsidwanso ntchito pokonza utoto ndi zokutira.
Njira:
Njira yokonzekera 4-chloro-3-fluorobenzoic acid nthawi zambiri imapezeka pochita benzoic acid ndi carbon tetrachloride ndi hydrogen fluoride. Choyamba, benzoic acid amachitidwa ndi carbon tetrachloride pamaso pa aluminium tetrachloride kupanga benzoyl chloride. Benzoyl chloride ndiye anachita ndi hydrogen fluoride mu zosungunulira organic kupanga 4-chloro-3-fluorobenzoic acid.
Zambiri Zachitetezo:
4-Chloro-3-fluorobenzoic acid imakhala yokhazikika kutentha kwa firiji, koma kukhudzana ndi zowonjezera zowonjezera komanso kutentha kwakukulu kuyenera kupewedwa. Zida zodzitetezera zoyenerera, monga magolovesi ndi magalasi, ziyenera kuvalidwa pogwira ntchito kuti musakhudze khungu ndi maso. Zabwino mpweya wabwino zinthu ayenera kuperekedwa pa ntchito.
