2-(Trifluoromethoxy) benzoic acid (CAS# 1979-29-9) Gabatarwa
TFMPA kristal ne mara launi, mai narkewa a cikin kaushi na halitta kamar benzene da ethanol. Yana da karfi acidity da oxidation, kuma yana kula da ruwa.
Amfani:
Ana amfani da TFMPA a ko'ina azaman mai haɓaka acid, mai oxidant da mai haɓakawa don esterification a cikin ƙwayoyin halitta. Zai iya haɓaka ci gaban halayen sinadarai da haɓaka zaɓi da yawan abin da zai haifar.
Hanya:
Shirye-shiryen TMPPA yawanci ana aiwatar da shi ta hanyar ɗaukar matakai da yawa. Ɗayan hanyar shiri na yau da kullum shine ta hanyar mayar da martani ga trifluoromethane tare da chloromethylbenzene don samar da 2-chloromethyl-3- (trifluoromethoxy) benzene (CF3CH2OH) da kuma abin da ke faruwa. Sa'an nan, da dauki substrate aka reacted tare da oxidizing wakili don samun TFMPA.
Bayanin Tsaro:
Amintaccen aiki na TMPPA yakamata ya bi ka'idodin aminci na dakin gwaje-gwaje. Saboda acidity da oxidation, ya kamata ya guje wa hulɗa da kayan wuta, masu kaushi na kwayoyin halitta da gas masu ƙonewa. Ya kamata a sa kayan kariya da suka dace kamar safofin hannu na lab, tabarau da tufafin lab yayin aiki. A lokaci guda kuma, ya kamata a yi amfani da shi a wuri mai kyau don hana tarin iskar gas mai cutarwa.
