Taw qhia
2-Fluoro-5-trifluoromethylaniline yog cov organic compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- Cov tsos mob: tsis muaj xim tsis muaj kob lossis cov hmoov tsis zoo.
- Solubility: soluble nyob rau hauv organic solvents, xws li ethanol, dimethylformamide, thiab lwm yam., insoluble nyob rau hauv dej.
Siv:
2-Fluoro-5-trifluoromethylaniline yog ib qho tseem ceeb ntawm cov tshuaj nruab nrab thiab feem ntau siv rau hauv cov organic synthesis tshwm sim. Nws tseem tuaj yeem siv rau hauv kev sib txuas ntawm dyes thiab coatings thiab hauv kev npaj cov khoom siv hluav taws xob.
Txoj kev:
Kev npaj ntawm 2-fluoro-5-trifluoromethylaniline tuaj yeem ua tiav los ntawm cov kauj ruam hauv qab no:
Fluoroaniline yog reacted nrog trifluorocarboxylic acid nyob rau hauv ib tug tsim nyog hnyav los tsim trifluoroformate ntawm 2-fluoro-5-trifluoromethylaniline.
Trifluoroformate yog reacted nrog lub hauv paus los tsim 2-fluoro-5-trifluoromethylaniline nyob rau hauv qhov kev txiav txim ntawm lub hauv paus.
Cov ntaub ntawv kev nyab xeeb:
Yuav tsum tau ceev faj txog kev nyab xeeb hauv qab no thaum tuav 2-fluoro-5-trifluoromethylaniline:
- Nws yog cov organic thiab muaj qee yam toxicity. Kev sib cuag lossis nqus tau cov tshuaj yuav ua rau muaj kev phom sij rau kev noj qab haus huv thiab kev sib cuag ncaj qha rau ntawm daim tawv nqaij thiab qhov muag yuav tsum zam.
- Hnav cov khoom tiv thaiv tus kheej tsim nyog xws li tsom iav, hnab looj tes thiab khaub ncaws tiv thaiv thaum ua haujlwm.
- Ua haujlwm nyob rau hauv qhov chaw kaw qhov cua kom tsis txhob nqus cov pa phem.
- Khaws kom deb ntawm qhov hluav taws kub thiab kub kub thaum khaws cia, thiab tsis txhob sib cuag nrog cov oxidants thiab muaj zog acids.
- Thaum siv lossis tuav cov khoom, cov txheej txheem kev nyab xeeb uas cuam tshuam yuav tsum tau ua raws li nruj me ntsis. Nyob rau hauv rooj plaub uas muaj xwm txheej, ua tib zoo ntsuas kev pab thawj zaug thiab nrhiav kev pab kho mob tam sim ntawd.
