Taw qhia

4-Trifluoromethoxyaniline yog ib qho organic compound. Cov hauv qab no yog cov lus qhia luv luv rau nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:

 

Zoo:

- Cov tsos: cov kua tsis muaj xim

- ntxhiab tsw: yam ntxwv ammonia tsw

- Solubility: Soluble nyob rau hauv cov organic solvents xws li cawv, ethers thiab ketones

 

Siv:

- 4-Trifluoromethoxyaniline tuaj yeem siv los ua ib qho nruab nrab ntawm cov organic synthesis thiab feem ntau yog siv los ua cov tshuaj fluorinating reagent hauv cov organic synthesis, xws li hauv cov synthesis ntawm catalysts hauv Suzuki cov tshuaj tiv thaiv.

 

Txoj kev:

- Txoj kev npaj ntawm 4-trifluoromethoxyaniline feem ntau yog siv cov tshuaj tiv thaiv amination. Cov khoom tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm aniline nrog trifluoromethanol.

 

Cov ntaub ntawv kev nyab xeeb:

- 4-Trifluoromethoxyaniline: yuav tsum tau saib xyuas kom tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag, thiab tsis txhob nqus los yog noj.

- Thaum siv thiab khaws cia, kev sib cuag nrog cov khoom xws li oxidants, muaj zog acids, muaj zog hauv paus, thiab hydrogen oxide yuav tsum raug zam kom tsis txhob muaj kev phom sij txaus ntshai.

- Ua raws li kev khaws cia tshuaj thiab tuav cov cai thiab kom tsis txhob muaj hluav taws kub thiab kub.
