Taw qhia
O-fluoroaniline, tseem hu ua 2-aminofluorobenzene. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm o-fluoroaniline:
Zoo:
- Cov tsos mob: O-fluoroaniline yog dawb crystalline khoom.
- Solubility: Soluble nyob rau hauv dej, cawv thiab ether solvents.
- Stability: txheeb ze nyob rau hauv ib txwm muaj mob.
Siv:
- Nws tuaj yeem siv los ua fluorescent brightener rau dyes lossis luminescent cov ntaub ntawv.
Txoj kev:
- Feem ntau, txoj kev npaj ntawm o-fluoroaniline cuam tshuam nrog hydrogenation ntawm fluoroaniline.
- Txoj kev npaj tshwj xeeb yog ua rau fluoroaniline nrog hydrogen nyob rau hauv lub xub ntiag ntawm catalyst thiab hloov cov fluorine atom nrog ib pawg amino los ntawm kev xaiv hydrogenation.
Cov ntaub ntawv kev nyab xeeb:
- O-fluaniline tsis ua rau muaj teeb meem loj rau tib neeg lub cev raws li kev siv ib txwm siv.
- Txawm li cas los xij, yuav tsum tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag, thiab yog tias muaj kev sib cuag, yaug tam sim nrog dej ntau.
- Thaum lub sijhawm ua haujlwm, yuav tsum tau saib xyuas kev tiv thaiv, xws li hnav tsom iav thiab hnab looj tes, thiab ua kom muaj cua zoo.
- Yuav tsum tau muab cia rau hauv qhov chaw qhuav, txias, kom deb ntawm cov khoom siv hluav taws xob thiab cov oxidizing.
