Taw qhia
2-Fluoro-4-chlorotoluene yog ib qho organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj, thiab cov ntaub ntawv kev nyab xeeb ntawm cov khoom sib xyaw no:
Zoo:
2-Fluoro-4-chlorotoluene yog cov kua tsis muaj xim nrog lub qab zib musky tsw. Nws yog soluble hauv cov kuab tshuaj organic xws li ethers thiab cawv, tab sis insoluble hauv dej.
Siv:
2-Fluoro-4-chlorotoluene yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis. Nws kuj tuaj yeem siv los ua cov kuab tshuaj.
Txoj kev:
2-Fluoro-4-chlorotoluene tuaj yeem npaj los ntawm reacting 2,4-dichlorotoluene nrog hydrogen fluoride. Cov tshuaj tiv thaiv no feem ntau tshwm sim nyob rau hauv acidic tej yam kev mob. Ua ntej, 2,4-dichlorotoluene thiab hydrogen fluoride ntxiv rau hauv cov hlab ntsha cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv yog nplawm ntawm qhov kub thiab txias rau lub sijhawm. Tom qab ntawd, los ntawm cov txheej txheem distillation thiab purification, 2-fluoro-4-chlorotoluene tau txais.
Cov ntaub ntawv kev nyab xeeb:
2-Fluoro-4-chlorotoluene yog irritating thiab corrosive. Kev sib cuag ntawm daim tawv nqaij thiab qhov muag yuav ua rau khaus thiab kub hnyiab. Cov hnab looj tes tiv thaiv tsim nyog, tsom iav, thiab khaub ncaws tiv thaiv yuav tsum hnav thaum tuav thiab siv nws. Yog nqus tau los yog nqus tau, nrhiav kev kho mob tam sim ntawd. Hais txog kev khaws cia thiab kev thauj mus los, kev sib cuag nrog cov tshuaj muaj zog oxidizing thiab muaj zog acids yuav tsum zam.
