Taw qhia
Potassium trifluoroacetate yog ib qho inorganic compound. Nws yog xim tsis muaj xim crystalline lossis dawb hmoov uas yog soluble hauv dej thiab cawv. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm potassium trifluoroacetate:
Zoo:
- Potassium trifluoroacetate yog corrosive heev thiab reacts sai nrog dej thiab tso tawm cov pa roj hydrogen fluoride.
- Nws yog ib qho muaj zog acidic tshuaj uas reacts nrog alkali los tsim cov ntsev sib xws.
- Nws tuaj yeem oxidized los ntawm oxidizing cov neeg ua haujlwm rau potassium oxide thiab carbon dioxide.
- Decomposes ntawm qhov kub siab los tsim cov tshuaj lom oxides thiab fluorides.
- Potassium trifluoroacetate muaj cov nyhuv corrosive rau cov hlau thiab tuaj yeem tsim cov tshuaj fluoride nrog cov hlau xws li tooj liab thiab nyiaj.
Siv:
- Potassium trifluoroacetate yog dav siv los ua catalyst nyob rau hauv cov organic synthesis tshuaj, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj fluorination.
- Nws tuaj yeem siv los ua cov khoom siv electrolyte hauv cov roj teeb ferromanganese thiab electrolytic capacitors.
- Potassium trifluoroacetate kuj tuaj yeem siv rau hauv kev kho hlau saum npoo los txhim kho corrosion kuj ntawm hlau nto.
Txoj kev:
- Potassium trifluoroacetate tuaj yeem tsim los ntawm cov tshuaj tiv thaiv ntawm trifluoroacetic acid nrog alkali hlau hydroxides.
Cov ntaub ntawv kev nyab xeeb:
- Potassium trifluoroacetate yog khaus thiab yuav tsum tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag.
- Cov hnab looj tes tiv thaiv, tsom iav kev nyab xeeb thiab cov khaub ncaws tiv thaiv yuav tsum hnav thaum ua haujlwm.
- Tsis txhob nqus nws cov plua plav lossis vapor thiab yuav tsum siv rau hauv qhov chaw muaj cua zoo.
