Taw qhia
O-trifluoromethylbenzoic acid yog cov organic compound. Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- Cov tsos mob: O-trifluoromethylbenzoic acid yog dawb crystalline hmoov los yog crystalline hmoov.
- Solubility: Nws yog soluble hauv cov kuab tshuaj organic xws li ethanol thiab ethers, tab sis insoluble hauv dej.
- Kev ruaj ntseg: Nws ruaj khov ntawm chav tsev kub, tab sis tuaj yeem ua rau muaj kev phom sij thaum raug tshav kub lossis muaj zog oxidizing cov neeg ua haujlwm.
Siv:
- O-trifluoromethylbenzoic acid feem ntau yog siv los ua ib qho tseem ceeb nruab nrab ntawm cov organic synthesis.
- Nws kuj tseem siv tau los ua cov photosensitizer, photopolymerizer, thiab pib rau cov tshuaj tiv thaiv polymerization.
Txoj kev:
- Kev npaj ntawm o-trifluoromethylbenzoic acid feem ntau pib los ntawm o-cresol. Ph-benzophenol yog reacted nrog trifluorocarboxylic anhydride los tsim o-trifluoromethylbenzoyl fluoride. Tom qab ntawd, qhov tshwm sim o-trifluoromethylbenzoyl fluoride yog reacted nrog lye los ua o-trifluoromethylbenzoic acid.
Cov ntaub ntawv kev nyab xeeb:
- O-trifluoromethylbenzoic acid yuav tsum muab cia rau hauv qhov chaw qhuav, txias, qhov cua zoo.
- Hnav cov iav tiv thaiv tsim nyog, suav nrog tsom iav, hnab looj tes, thiab daim npog ntsej muag.
- Tsis txhob nqus pa, noj, lossis kev sib cuag ntawm daim tawv nqaij, thiab ntxuav tam sim ntawd thaum muaj kev sib cuag tsis raug.
- Nws tuaj yeem tsim kev puas tsuaj rau ib puag ncig, yuav tsum tau saib xyuas kom zoo thiab pov tseg cov khoom pov tseg.
- Yog xav paub ntxiv txog kev nyab xeeb, thov mus saib Daim Ntawv Qhia Kev Nyab Xeeb tshwj xeeb.
