2-(Trifluoromethoxy)benzoic acid (CAS# 1979-29-9) Selelekela

2-(trifluoromethoxy)benzoic acid (e khutsufalitsoeng joalo ka TFMPA) ke motsoako oa tlhaho. E latelang ke tlhaloso ya sebopeho, tshebediso, tlhahiso le tlhahisoleseding ya polokeho ya TFMPA:Tlhaho:
TFMPA ke kristale e se nang 'mala, e qhibilihang ka har'a metsoako ea tlhaho e kang benzene le ethanol. E na le asiti e matla le oxidation, 'me e utloela metsi.

Sebelisa:
TFMPA e sebelisoa haholo joalo ka motsoako oa asiti, oxidant le mohloli oa esterification ho organic synthesis. E ka khothalletsa tsoelo-pele ea lik'hemik'hale le ho ntlafatsa khetho le lihlahisoa tsa karabelo.

Mokhoa:
Tokiso ea TFMPA hangata e etsoa ke karabelo ea mehato e mengata. Mokhoa o mong o tloaelehileng oa ho lokisa ke ka ho arabela trifluoromethane ka chloromethylbenzene ho hlahisa 2-chloromethyl-3-(trifluoromethoxy) benzene (CF3CH2OH) le substrate ea reaction. Ebe, substrate ea karabelo e arajoa ka oxidizing ho fumana TFMPA.

Lintlha tsa Tšireletseho:
Ts'ebetso e bolokehileng ea TFMPA e lokela ho latela melaoana ea polokeho ea laboratoring. Ka lebaka la acidity ea eona le oxidation, e lokela ho qoba ho kopana le lisebelisoa tse tukang, li-solvents le likhase tse tukang. Lisebelisoa tse nepahetseng tsa ts'ireletso joalo ka liatlana tsa lab, likhalase le liaparo tsa lab li lokela ho apesoa nakong ea ts'ebetso. Ka nako e ts'oanang, e lokela ho sebetsoa sebakeng se nang le moea o motle ho thibela ho bokellana ha likhase tse kotsi.
