Taw qhia

M-fluorotoluene yog ib qho organic compound. Nws yog cov kua uas tsis muaj xim nrog cov ntxhiab tsw zoo li benzene. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm m-fluorotoluene:

 

Zoo:

- Ceev: approx. 1.15 g / cm³

- Solubility: Soluble nyob rau hauv non-polar solvents xws li ether thiab benzene, insoluble nyob rau hauv dej

 

Siv:

- Nws kuj tuaj yeem siv los ua cov kuab tshuaj, tshwj xeeb tshaj yog nyob rau hauv cov organic synthesis tshuaj, xws li fluorination thiab arylation.

 

Txoj kev:

- M-fluorotoluene tuaj yeem npaj tau los ntawm cov tshuaj tiv thaiv ntawm benzene thiab fluoromethane nyob rau hauv lub xub ntiag ntawm ib tug catalyst rau fluorine tebchaw. Cov catalysts feem ntau yog cuprous fluoride (CuF) lossis CuI, uas tshwm sim ntawm qhov kub thiab txias.

 

Cov ntaub ntawv kev nyab xeeb:

- M-fluorotoluene yog cov kua nplaum uas tuaj yeem hlawv thaum raug hluav taws kub, kub kub, lossis cov organic peroxides.

- Nws yog khaus rau ntawm daim tawv nqaij thiab qhov muag, thiab cov khoom siv tiv thaiv tus kheej xws li hnab looj tes thiab tsom iav yuav tsum hnav thaum siv.

- Tsis txhob sib cuag nrog cov oxidizing muaj zog tiv thaiv kev ua phem.

- Khaws kom deb ntawm qhov hluav taws kub, nyob rau hauv qhov chaw uas muaj cua zoo, thiab tsis txhob sib cuag nrog huab cua.

- Yog tias nqus tau los yog nkag mus rau ntawm daim tawv nqaij, ntxuav tam sim ntawd thiab nrhiav kev kho mob.
