2- (Trifluoromethoxy) benzoic acid (CAS# 1979-29-9) Okwu mmalite.
TFMPA bụ kristal enweghị agba, soluble na organic mgbaze dị ka benzene na ethanol. Ọ nwere acidity siri ike na oxidation, ọ na-enwe mmetụta maka mmiri.
Jiri:
A na-eji TFMPA eme ihe n'ọtụtụ ebe dị ka ihe na-eme ka acid, oxidant na ihe na-eme ka esterification na njikọ organic. Ọ nwere ike ịkwalite ọganihu nke mmeghachi omume kemịkal ma melite nhọrọ na mkpụrụ nke mmeghachi omume.
Usoro:
A na-emekarị nkwadebe nke TMPPA site na mmeghachi omume ọtụtụ nzọụkwụ. Otu usoro nkwadebe a na-emekarị bụ site n'imeghachi trifluoromethane na chloromethylbenzene iji mepụta 2-chloromethyl-3- (trifluoromethoxy) benzene (CF3CH2OH) na ntinye mmeghachi omume. Mgbe ahụ, a na-eji ihe na-emepụta ihe na-emeghachi omume mmeghachi omume iji nweta TFMPA.
Ozi nchekwa:
Ọrụ nchekwa nke TFMPA kwesịrị ịgbaso ụkpụrụ nchekwa nke ụlọ nyocha. N'ihi acidity ya na oxidation, ọ kwesịrị izere kọntaktị na ihe ndị na-ere ọkụ, ihe mgbaze organic na gas na-ere ọkụ. Ekwesịrị iyi akụrụngwa nchekwa kwesịrị ekwesị dị ka uwe ụlọ nyocha, goggles na uwe ụlọ nyocha mgbe a na-arụ ọrụ. N'otu oge ahụ, a ga-arụ ọrụ na mpaghara ikuku nke ọma iji gbochie nchịkọta nke gas na-emerụ ahụ.
