Taw qhia
4-Fluoro-3-nitrotoluene 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:
4-Fluoro-3-nitrotoluene yog cov xim tsis muaj xim crystalline uas ruaj khov ntawm chav tsev kub. Nws yooj yim soluble hauv cov kuab tshuaj organic xws li ethanol, chloroform, thiab dimethylformamide.
Siv:
4-fluoro-3-nitrotoluene feem ntau yog siv los ua cov khoom pib lossis nruab nrab hauv cov organic synthesis tshwm sim. Tsis tas li ntawd, nws tseem tuaj yeem siv los ua cov khoom siv raw rau fungicides thiab tshuaj tua kab.
Txoj kev:
4-Fluoro-3-nitrotoluene tuaj yeem ua ke los ntawm ntau txoj hauv kev. Ib txoj hauv kev yog los ntawm kev qhia fluorine thiab nitro pawg rau hauv toluene. Cov tshuaj tiv thaiv no feem ntau siv hydrogen fluoride thiab nitric acid ua cov tshuaj tiv thaiv, thiab cov tshuaj tiv thaiv yuav tsum tau tswj kom zoo.
Cov ntaub ntawv kev nyab xeeb:
Thaum siv 4-fluoro-3-nitrotoluene, yuav tsum tau ceev faj txog kev nyab xeeb hauv qab no:
Nws yog ib yam tshuaj uas muaj qhov ua rau lub qhov muag, tawv nqaij, thiab ua pa thiab yuav tsum zam.
Cov cuab yeej tiv thaiv tus kheej xws li hnab looj tes, tsom iav, thiab cov khaub ncaws tiv thaiv yuav tsum tau siv thaum ua haujlwm.
Nws yuav tsum tau siv nyob rau hauv qhov chaw zoo-ventilated kom tsis txhob nqus nws vapors.
Sim kom tsis txhob sib cuag nrog oxidants, muaj zog acids, los yog muaj zog bases kom tsis txhob muaj kev phom sij txaus ntshai.
