Daim ntawv thov
1. Trifluoroacetic acid yog dav siv los ua cov ion volatile -pairing tus neeg sawv cev nyob rau hauv reversed-phase kua chromatography (RPLC) rau peptide thiab protein tsom xam, pab txhawb kev sib cais efficiency thiab nrhiav kom tau rhiab heev.
2. Trifluoroacetic acid CAS 76-05-1 ua hauj lwm pab raws li ib tug muaj zog organic acid thiab ntau yam hnyav nyob rau hauv cov organic synthesis, tshwj xeeb tshaj yog rau deprotection cov tshuaj tiv thaiv nyob rau hauv peptide chemistry thiab raws li ib tug catalyst nyob rau hauv ntau yam transformation.
3. Trifluoroacetic acid yog ua hauj lwm nyob rau hauv lub synthesis ntawm pharmaceuticals thiab agrochemicals, xws li raws li ib tug ntawm cov pab pawg neeg trifluoromethyl nyob rau hauv kev tsim tshuaj, thiab nyob rau hauv lub nto hloov kho ntawm polymers thiab fibers.
Cia thiab ceev faj
1. Khaws Trifluoroacetic acid nyob rau hauv lub kaw ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntim ntim cov thawv ntim khoom tiv thaiv (iav lossis PTFE) hauv qhov txias, qhuav, zoo- thaj chaw qhov cua, kom deb ntawm tshav kub, hluav taws xob, thiab cov khoom siv tsis sib xws.
2. Khaws Trifluoroacetic acid CAS 76-05-1 nruj me ntsis kom deb ntawm cov khoom muaj zog oxidizing, muaj zog hauv paus, thiab hlau, vim Trifluoroacetic acid yog corrosive heev thiab reacts hnyav nrog dej, tso pa tawm cov pa phem.
3. Kov Trifluoroacetic acid siv cov cuab yeej tiv thaiv tus kheej tsim nyog suav nrog cov kua qaub- cov hnab looj tes tiv thaiv (butyl roj hmab), daim npog ntsej muag, thiab hauv lub hood fume, vim Trifluoroacetic acid ua rau kub hnyiab thiab ua pa puas.
Kev kub ceev teb rau cov dej xau
1. Cais qhov chaw nchuav, hnav cov khoom tiv thaiv tag nrho nrog rau tus kheej - muaj cov cuab yeej ua pa, thiab muaj cov kua Trifluoroacetic acid siv cov khoom siv tsis zoo xws li xuab zeb, tiv thaiv kev nkag mus rau hauv cov dej ntws los yog cov dej.
2. Neutralize Trifluoroacetic acid CAS 76-05-1 ua tib zoo nrog dej qab zib tshauv lossis txiv qaub, tom qab ntawd sau rau hauv cov thawv ntim khoom uas muaj cov tshuaj tiv thaiv corrosion-resistant rau pov tseg raws li cov khoom siv phom sij.
3. Cov neeg ua hauj lwm tu Trifluoroacetic acid spills yuav tsum siv tsis yog - cov cuab yeej hluav taws xob thiab xyuas kom muaj qhov cua txaus, vim cov vapors tuaj yeem tsim cov khoom tawg thiab Trifluoroacetic acid raug cais rau kev thauj mus los (UN 2699, Hazard Class 8, Packing Group I).
Cov ntaub ntawv kev nyab xeeb
1. Trifluoroacetic acid yog ib yam khoom corrosive (GHS05, Danger) ua rau tawv nqaij kub hnyiab, mob qhov muag loj (H314, H318), thiab muaj teeb meem yog nqos tau (H302) lossis nqus tau pa (H332).
2. Trifluoroacetic acid CAS 76-05-1 muaj NFPA kev ntsuam xyuas kev noj qab haus huv ntawm 4 (muaj kev phom sij hnyav), flash point tsis siv tau (tsis yog nplaim taws), tab sis thermal decomposition ua rau cov pa phem xws li carbon oxides thiab hydrogen fluoride .
3. Trifluoroacetic acid yog tshuaj lom heev rau cov dej hauv lub neej nrog ntev - cov teebmeem ntev (H400, H412), muaj qhov kub ntawm 72 degree, qhov ceev ntawm 1.535 g / mL, thiab miscible nrog dej.
