Taw qhia

Dibromodifluoromethane (CBr2F2), tseem hu ua halothane (halothane, trifluoromethyl bromide), yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm dibromodifluoromethane:

 

Zoo:

- Cov tsos: cov kua tsis muaj xim

- Solubility: soluble hauv ethanol, ether thiab chloride, me ntsis soluble hauv dej

- Toxicity: muaj cov tshuaj loog thiab tuaj yeem ua rau muaj kev nyuaj siab hauv plawv

 

Siv:

- Cov tshuaj loog: Dibromodifluoromethane, ib zaug dav siv rau cov tshuaj loog thiab cov tshuaj loog, tam sim no tau hloov los ntawm kev siv tshuaj loog ntau dua thiab nyab xeeb.

 

Txoj kev:

Kev npaj ntawm dibromodimomethane tuaj yeem ua tiav los ntawm cov kauj ruam hauv qab no:

Bromine reacted nrog fluorine ntawm qhov kub thiab txias kom muab fluorobromide.

Fluorobromide yog reacted nrog methane nyob rau hauv ultraviolet hluav taws xob los tsim dibromodifluoromethane.

 

Cov ntaub ntawv kev nyab xeeb:

- Dibromodifluoromethane muaj cov tshuaj loog thiab yuav tsum tau siv nrog ceev faj, tshwj xeeb tshaj yog tsis muaj kev taw qhia kev tshaj lij.

- Kev kis mus ntev rau dibromodifluoromethane tuaj yeem ua rau muaj kev cuam tshuam rau daim siab.

- Tej zaum yuav ua rau khaus yog tias nws nkag mus rau hauv qhov muag, tawv nqaij, lossis ua pa.

- Thaum siv dibromodifluoromethane, nplaim taws lossis kub kub yuav tsum zam vim nws yog nplaim taws.

- Thaum siv dibromodifluoromethane, ua raws li kev kuaj xyuas kom raug thiab kev tiv thaiv tus kheej.
