Mawu Oyamba

Bromobenzene ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chitetezo cha bromobenzene:

 

Ubwino:

1. Ndi madzi opanda mtundu, owoneka bwino mpaka achikasu potentha kutentha.

2. Lili ndi fungo lapadera, ndipo silisungunuka ndi madzi, ndipo limasakanikirana ndi zosungunulira zambiri za organic monga mowa ndi ether.

3. Bromobenzene ndi mankhwala a hydrophobic omwe amatha kukhala oxidized ndi okosijeni ndi ozoni.

 

Gwiritsani ntchito:

1. Amagwiritsidwa ntchito kwambiri muzochita za organic synthesis, monga reagent yofunika komanso yapakatikati.

2. Itha kugwiritsidwanso ntchito ngati chowotcha moto popanga mapulasitiki, zokutira ndi zinthu zamagetsi.

 

Njira:

Bromobenzene imakonzedwa makamaka ndi njira ya ferromide. Iron imayamba kupangidwa ndi bromine kupanga ferric bromide, kenako iron bromide imapangidwa ndi benzene kupanga bromobenzene. Zomwe zimachitikira nthawi zambiri zimakhala zotentha, ndipo m'pofunika kumvetsera chitetezo pamene zomwe zikuchitika.

 

Zambiri Zachitetezo:

1. Ili ndi kawopsedwe wambiri komanso kuwononga.

2. Kuwonekera kwa bromobenzene kungayambitse kuyabwa m'maso, khungu ndi kupuma kwa thupi la munthu, komanso kumayambitsa poizoni.

3. Mukamagwiritsa ntchito bromobenzene, zida zoyenera zodzitetezera ziyenera kuvala, monga magolovesi, magalasi otetezera ndi masks otetezera.

4. Ndipo onetsetsani kuti ikugwiritsidwa ntchito pamalo abwino kuti mupewe kukhudzana kwa nthawi yayitali kapena kupuma.

5. Mukakumana ndi bromobenzene mwangozi, muyenera kutsuka gawo lomwe lakhudzidwa ndi madzi ambiri ndikupempha thandizo lachipatala.
