2-(Trifluoromethoxy)benzoic acid (CAS# 1979-29-9) Chiyambi
TFMPA ndi kristalo wopanda mtundu, wosungunuka mu zosungunulira monga benzene ndi ethanol. Lili ndi acidity yamphamvu komanso okosijeni, komanso limamva madzi.
Gwiritsani ntchito:
TFMPA imagwiritsidwa ntchito kwambiri ngati chothandizira asidi, okosijeni komanso chothandizira kuti esterification mu kaphatikizidwe ka organic. Iwo akhoza kulimbikitsa kupita patsogolo kwa mankhwala anachita ndi kusintha selectivity ndi zokolola za anachita.
Njira:
Kukonzekera kwa TFMPA nthawi zambiri kumachitika ndi njira zingapo. Njira imodzi yodziwika bwino yokonzekera ndikumachitira trifluoromethane ndi chloromethylbenzene kupanga 2-chloromethyl-3-(trifluoromethoxy) benzene (CF3CH2OH) ndi gawo lapansi. Kenako, gawo lapansi limayendetsedwa ndi oxidizing kuti mupeze TFMPA.
Zambiri Zachitetezo:
Kayendetsedwe ka chitetezo ka TFMPA kuyenera kutsatira malamulo achitetezo a labotale. Chifukwa cha acidity yake ndi okosijeni, iyenera kupewa kukhudzana ndi zinthu zoyaka moto, zosungunulira organic ndi mpweya woyaka. Zida zodzitetezera zoyenerera monga magolovesi a labu, magalasi ndi zovala za labu ziyenera kuvalidwa panthawi yogwira ntchito. Panthawi imodzimodziyo, iyenera kugwiritsidwa ntchito pamalo opuma mpweya wabwino kuti asatengeke ndi mpweya woipa.
