Taw qhia
5-Fluoro-2-nitrotoluene 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: 5-fluoro-2-nitrotoluene yog xim tsis muaj xim lossis yellowish crystal.
- Cov khoom siv tshuaj: 5-fluoro-2-nitrotoluene muaj tshuaj lom neeg ruaj khov thiab tsis yooj yim rau volatile.
Siv:
- Tshuaj intermediates: 5-fluoro-2-nitrotoluene tuaj yeem siv los ua ib qho nruab nrab hauv cov organic synthesis rau kev sib txuas ntawm lwm cov organic compounds.
Txoj kev:
5-Fluoro-2-nitrotoluene tuaj yeem ua ke los ntawm:
Nyob rau hauv alkaline tej yam kev mob, 2-chlorotoluene reacted nrog hydrogen fluoride kom tau 5-fluoro-2-chlorotoluene, thiab ces reacted nrog nitric acid kom tau lub hom phiaj cov khoom 5-fluoro-2-nitrotoluene.
Nyob rau hauv lub xub ntiag ntawm cawv, 2-nitrotoluene yog reacted nrog hydrogen bromide, ces reacted nrog hydrogen fluoride, thiab thaum kawg cov khoom yog npaj los ntawm lub cev qhuav dej.
Cov ntaub ntawv kev nyab xeeb:
- 5-Fluoro-2-nitrotoluene yog ib yam tshuaj uas hnyav rau ntawm daim tawv nqaij thiab ob lub qhov muag, yog li hnav hnab looj tes tiv thaiv thiab tsom iav kom tsis txhob sib cuag ncaj qha.
- Kev ceev faj yuav tsum tau them rau kev tiv thaiv hluav taws thiab tawg thaum siv thiab tuav, thiab tsis txhob sib cuag nrog cov nplaim taws, qhov kub thiab txias lossis lwm qhov hluav taws kub.
- Thov khaws thiab thauj kom zoo, kom deb ntawm oxidants thiab combustibles.
- Thaum noj los yog nqus tau, nrhiav kev kho mob tam sim ntawd thiab muab cov ntaub ntawv hais txog cov tshuaj.
