Taw qhia
2-Chloro-4-fluorobenzoic acid yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 2-chloro-4-fluorobenzoic acid:
Zoo:
- Cov tsos mob: 2-Chloro-4-fluorobenzoic acid yog dawb crystalline khoom.
- Solubility: Nws muaj tsawg solubility hauv dej, tab sis muaj zoo solubility nyob rau hauv organic solvents (xws li, ethanol, acetone).
- Stability: Nws yog ib qho chaw ruaj khov, tab sis kev sib cuag nrog cov oxidants muaj zog thiab cov kua qaub yuav tsum zam.
Siv:
- Chemical intermediates: 2-chloro-4-fluorobenzoic acid tuaj yeem siv los ua cov tshuaj intermediates hauv organic synthesis.
- Surfactant: Nws tuaj yeem siv los ua cov khoom siv raw rau surfactants thiab muaj qhov ua haujlwm zoo ntawm qhov chaw thiab cov khoom tawg.
- Cov ntaub ntawv photosensitive: 2-chloro-4-fluorobenzoic acid tuaj yeem siv los npaj cov ntaub ntawv photosensitive, xws li cov nplaum nplaum.
Txoj kev:
2-Chloro-4-fluorobenzoic acid tuaj yeem tau txais los ntawm fluorochloro-hloov cov tshuaj tiv thaiv ntawm p-dichlorobenzoic acid lossis difluorobenzoic acid. Cov kev npaj tshwj xeeb yuav suav nrog fluorochloro-hloov pauv, fluorination lossis lwm yam kev hloov pauv uas tsim nyog.
Cov ntaub ntawv kev nyab xeeb:
- Toxicity: 2-chloro-4-fluorobenzoic acid yog ib qho organofluorine compound, uas tsis muaj tshuaj lom ntau dua li cov tshuaj organofluorine. Txawm li cas los xij, yuav tsum tau saib xyuas kom tsis txhob nqus los yog sib cuag.
- Irritation: Nws tuaj yeem ua rau qhov muag, tawv nqaij thiab ua pa thiab yuav tsum tau ntxuav tam sim tom qab sib cuag.
- Cov tshuaj tua hluav taws: Hauv qhov hluav taws kub, kev tua hluav taws yuav tsum tau ua nrog cov tshuaj tua hluav taws tsim nyog xws li carbon dioxide, ua npuas ncauj lossis hmoov qhuav, tsis txhob siv dej tua hluav taws vim tias nws muaj cov dej solubility tsawg.
- Cia: 2-Chloro-4-fluorobenzoic acid yuav tsum muab cia rau hauv qhov chaw qhuav, qhov cua zoo, kom deb ntawm hluav taws thiab muaj zog oxidants.
