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

2-(trifluoromethoxy) benzoic acid (abbreviated li TMPA) yog cov organic compound. Cov hauv qab no yog cov lus piav qhia ntawm qhov xwm txheej, kev siv, kev tsim thiab kev nyab xeeb cov ntaub ntawv ntawm TMPA: Xwm:
TMPA yog cov xim tsis muaj xim, soluble hauv cov kuab tshuaj organic xws li benzene thiab ethanol. Nws muaj zog acidity thiab oxidation, thiab rhiab heev rau dej.

Siv:
TMPA yog dav siv los ua cov kua qaub catalyst, oxidant thiab catalyst rau esterification hauv organic synthesis. Nws tuaj yeem txhawb kev nce qib ntawm cov tshuaj tiv thaiv tshuaj thiab txhim kho kev xaiv thiab tawm los ntawm cov tshuaj tiv thaiv.

Txoj kev:
Kev npaj ntawm TMPA feem ntau yog ua los ntawm ntau cov tshuaj tiv thaiv. Ib txoj hauv kev zoo tshaj plaws ntawm kev npaj yog los ntawm reacting trifluoromethane nrog chloromethylbenzene los tsim 2-chloromethyl-3-(trifluoromethoxy) benzene (CF3CH2OH) thiab cov tshuaj tiv thaiv substrate. Tom qab ntawd, cov tshuaj tiv thaiv substrate yog reacted nrog tus neeg sawv cev oxidizing kom tau TMPA.

Cov ntaub ntawv kev nyab xeeb:
Kev ua haujlwm nyab xeeb ntawm TMPA yuav tsum ua raws li cov cai tswj kev nyab xeeb ntawm chav kuaj. Vim nws acidity thiab oxidation, nws yuav tsum tsis txhob sib cuag nrog cov ntaub ntawv flammable, organic solvents thiab combustible gases. Cov cuab yeej tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav thiab cov khaub ncaws hauv chav kuaj yuav tsum tau hnav thaum ua haujlwm. Nyob rau tib lub sijhawm, nws yuav tsum tau ua haujlwm nyob rau hauv qhov chaw zoo-ventilated los tiv thaiv cov tsub zuj zuj ntawm cov pa phem.
