Taw qhia
4-Fluoro-2-aminobenzoic 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: 4-Fluoro-2-aminobenzoic acid yog dawb mus rau daj crystalline hmoov.
- Solubility: Nws muaj tsawg solubility nyob rau hauv dej thiab soluble nyob rau hauv cov organic solvents xws li ether thiab cawv.
Siv:
- Nws kuj tseem siv tau los ua ib qho catalyst hauv organic synthesis.
Txoj kev:
- 4-Fluoro-2-aminobenzoic acid tuaj yeem tau los ntawm 4-fluorination cov tshuaj tiv thaiv ntawm benzoic acid. Txoj kev npaj ib txwm yog siv cov tshuaj fluorinating xws li hydrogen fluoride los yog trifluoride los ua cov tshuaj tiv thaiv hauv acidic.
Cov ntaub ntawv kev nyab xeeb:
- 4-Fluoro-2-aminobenzoic acid tsis tshua muaj tshuaj lom, tab sis nws tseem ceeb heev rau kev saib xyuas kev nyab xeeb thiab tsis txhob sib cuag nrog daim tawv nqaij, qhov muag, thiab ua pa.
- Hnav cov khoom tiv thaiv tus kheej tsim nyog xws li hnab looj tes tshuaj, tsom iav, thiab lub tshuab ua pa thaum siv lossis tuav.
- Thaum lub sij hawm khaws cia thiab kev thauj mus los, yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag nrog cov oxidants thiab muaj zog acidic tshuaj tiv thaiv ignition thiab kub kub.
