CAS: 2966-50-9 Silver Trifluoroacetate

Cov tshuaj sib xyaw ua ke nrog CAS Tsis yog . 2966-50-9 yog Silver Trifluoroacetate, nrog cov qauv molecular ntawm C₂AgF₃O₂ thiab molecular hnyav ntawm 220.88 g / mol. Lub compound yog lub teeb beige rau grey crystalline hmoov, tsw ntxhiab, rhiab heev rau cov av noo, thiab yuav tsum tau muab kaw cia.
Lub melting point ntawm Silver Trifluoroacetate yog 257-260℃(decomposition), thiab nws yog yooj yim soluble nyob rau hauv dej thiab polar solvents xws li methanol thiab ethanol, tab sis insoluble nyob rau hauv non-polar solvents xws li n-hexane. Nws cov tshuaj aqueous yog weakly acidic thiab yooj yim deliquesces nyob rau hauv cov huab cua. Tsis tas li ntawd, nws yog soluble hauv ether (750 mL dissolves 33.5 g), benzene (30 mL dissolves 1.9 g) thiab trifluoroacetic acid (solubility 15.2% ntawm 30 degree), thiab nws kuj muaj qee yam solubility hauv toluene thiab xylene.

1. Silver trifluoroacetate yog dawb crystalline khoom nrog ib tug muaj zog pungent tsw.
2. Nws yog soluble hauv cov kuab tshuaj organic thiab dej, tab sis nws cov solubility hauv dej kuj tsawg.
3. Nws yog ruaj khov nyob rau hauv huab cua, tab sis yuav deliquesce nyob rau hauv tej yam kev mob ntawm high humidity.

Kev siv:

Organic Synthesis Catalysis:
Silver Trifluoroacetate yog siv los ua Lewis acid catalyst rau cov synthesis ntawm hydrazones thiab kev npaj ntawm trifluoroacetate compounds (xws li triethylsilyl trifluoroacetate thiab triphenylmethyl trifluoroacetate).
Ua ke nrog iodine, nws tuaj yeem txhawb nqa lub nplhaib iodination thiab regioselective alkylation cov tshuaj tiv thaiv, xws li kev npaj ntawm 4-iodoveratrole los ntawm veratrole.
Synthesis ntawm Fluorinated Compounds:
Raws li cov ntsev ntsev ntawm trifluoroacetic acid, nws tuaj yeem siv los qhia cov pab pawg trifluoromethyl los ua cov tshuaj fluorinated lossis cov khoom siv hluav taws xob.

Kev khaus khaus: khaus khaus heev rau ntawm daim tawv nqaij thiab qhov muag (H315, H319), yuav ua rau cov nyiaj tso tawm, hnav hnab looj tes thiab tsom iav thaum ua haujlwm, thiab ua haujlwm hauv lub hood fume.
Kev pheej hmoo ib puag ncig: Muaj tshuaj lom rau cov kab mob hauv dej (H400), zam kev tso tawm rau ib puag ncig.
Cia tej yam kev mob: Khaws rau hauv qhov chaw txias thiab qhuav (tsawg dua lossis sib npaug li 30 degree) tom qab sib khi, kom deb ntawm lub teeb thiab noo noo, thiab kom deb ntawm cov oxidants muaj zog.
