Daim ntawv thov
1. Sodium trifluoroacetate yog siv los ua ib tus neeg sawv cev trifluoromethylating rau aromatic halides, aldehydes, thiab ketones, ua kom muaj kev taw qhia ntawm fluorine atoms los txhim kho kev lom zem thiab kev ruaj ntseg hauv kev tsim tshuaj.
2. Sodium trifluoroacetate CAS 2923-}18-4 ua hauj lwm raws li difluorocarbene precursor rau alkenes thiab yog siv nyob rau hauv acid-catalyzed cov tshuaj tiv thaiv thiab ua ib tug intermediate rau active tshuaj cov khoom xyaw (APIs).
3. Sodium trifluoroacetate ua ib qho tsis nyob rau hauv biochemical kev soj ntsuam kom tswj pH rau enzyme kev ua, raws li ib tug derivatizing tus neeg sawv cev nyob rau hauv huab hwm coj spectrometry, thiab nyob rau hauv kev loj hlob ntawm fluorinated polymers nrog tshuaj tiv thaiv rau coatings.
Cia thiab ceev faj
1. Khaws Sodium trifluoroacetate nyob rau hauv ib lub thawv kaw nruj nreem nyob rau hauv inert gas (argon) nyob rau hauv ib tug txias, qhuav qhov chaw nrog pom zoo kub ntawm chav tsev kub (RT) nyob rau hauv ib tug maub qhov chaw nyob rau hauv qab no 15 degree, raws li nws yog hygroscopic.
2. Khaws Sodium trifluoroacetate CAS 2923-18-4 nruj me ntsis kom deb ntawm cov muaj zog oxidizing cov neeg ua haujlwm, cov hauv paus muaj zog, thiab cov dej noo los tiv thaiv kev puas tsuaj.
3. Kov Sodium trifluoroacetate siv cov cuab yeej tiv thaiv tus kheej tsim nyog nrog rau cov hnab looj tes nitrile, tsom iav kev nyab xeeb, thiab hauv lub fume hood kom tsis txhob muaj plua plav tsim thiab tiv thaiv ntawm daim tawv nqaij thiab qhov muag.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm ntawm qhov chaw nchuav, hnav cov khoom tiv thaiv tag nrho nrog rau lub tshuab ua pa uas tsim nyog, thiab cheb cov khoom Sodium trifluoroacetate rau hauv cov thawv ntim, cov ntawv sau tsis tsim cov plua plav.
2. Tiv thaiv kom tsis txhob spilled Sodium trifluoroacetate CAS 2923-18-4 los ntawm kev nkag mus rau hauv cov dej ntws los yog hauv dej, vim nws muaj tshuaj lom heev rau cov dej hauv dej nrog cov teebmeem ntev (H400, H412).
3. Cov neeg ua haujlwm tu Sodium trifluoroacetate spills yuav tsum muab pov tseg pov tseg raws li ib puag ncig cov cai thiab tsis txhob tso rau hauv ib puag ncig.
Cov ntaub ntawv kev nyab xeeb
1. Sodium trifluoroacetate is fatal if swallowed (H300) with GHS signal word "Danger" according to TCI, though other sources classify it as "Warning" (H315-H319-H335) with oral LD50 >7000 mg/kg hauv nas.
2. Sodium trifluoroacetate CAS 2923-}18-4 yog tshuaj lom heev rau cov dej hauv lub neej nrog kev cuam tshuam ntev (H400, H412) thiab yuav tsum tau ceev faj cov lus qhia P273 (tsis txhob tso tawm rau ib puag ncig) thiab P391 (suav pov tseg).
3. Sodium trifluoroacetate muaj melting point ntawm 205-207℃(dec.), ceev ntawm 1.49 g / mL, yog soluble nyob rau hauv dej (625 g / L ntawm 20 degree), thiab yog tsis combustible, tab sis thermal decomposition ua cov pa phem xws li carbon oxides, hydrogen oxide fluoride.
