Mawu Oyamba

3,4-Difluorobromobenzene ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:

 

Ubwino:

Maonekedwe: 3,4-Difluorobromobenzene ndi madzi opanda mtundu mpaka kuwala achikasu.

Kachulukidwe: pafupifupi. 1.65g/cm³

Kusungunuka: 3,4-difluorobromobenzene imasungunuka mu zosungunulira za organic ndipo pafupifupi osasungunuka m'madzi.

 

Gwiritsani ntchito:

Makampani opanga zamagetsi: chifukwa cha zinthu zabwino zamagetsi, 3,4-difluorobromobenzene nthawi zambiri amagwiritsidwa ntchito ngati chigawo cha organic semiconductor materials.

 

Njira:

Njira yokonzekera 3,4-difluorobromobenzene imakhala ndi izi:

Choyamba, bromobenzene ndi bromoflurane amachitira kupanga 2,3,4,5-tetrabromofluorobenzene.

2,3,4,5-tetrabromofluorobenzene kenako imachitidwa ndi hydrofluoric acid kuti ipeze 3,4-difluorobromobenzene.

 

Zambiri Zachitetezo:

3,4-Difluorobromobenzene ndi poizoni ndipo chisamaliro chiyenera kutengedwa kuti musakhudze khungu ndi kupuma mpweya wake.

Ndondomeko zoyenera za labotale ndi njira zodzitetezera monga kuvala magolovesi odzitetezera, magalasi, ndi zotchinga zoteteza ziyenera kutsatiridwa mukamagwiritsa ntchito.

Posunga, ziyenera kusungidwa kutali ndi zinthu zomwe zimayaka moto ndi zowonjezera zowonjezera, ndipo pewani kukhudzana ndi asidi amphamvu kapena alkalis.

Potaya zinyalala, zimayenera kutayidwa motsatira malamulo ndi malamulo oyenera kupewa kuwononga chilengedwe.
