Mawu Oyamba

 

Ubwino:

Bromophenol ndi kristalo wopanda mtundu kapena woyera wokhala ndi fungo lachilendo la phenolic. Ndi sungunuka organic solvents pa firiji ndi pang'ono sungunuka m'madzi. Bromophenol ndi gawo lofooka la acidic lomwe limatha kusinthidwa ndi maziko monga sodium hydroxide. Ikhoza kuwola ikatenthedwa.

 

Gwiritsani ntchito:

Bromophenol nthawi zambiri amagwiritsidwa ntchito ngati zopangira zofunikira komanso zapakatikati mu kaphatikizidwe ka organic. Bromophenol itha kugwiritsidwanso ntchito ngati mankhwala ophera mabakiteriya.

 

Njira:

Pali njira ziwiri zazikulu zopangira bromophenol. Imodzi imakonzedwa ndi zomwe benzene bromide ndi sodium hydroxide. Zina zimakonzedwa ndi resorcinol ndi bromination. Njira yeniyeni yokonzekera ikhoza kusankhidwa malinga ndi zosowa zanu.

 

Zambiri Zachitetezo:

Bromophenol ndi mankhwala oopsa, ndipo kuwonetsa kapena kutulutsa mpweya wake kungakhale ndi zotsatira zoyipa pa thanzi la munthu. Mukamagwira bromophenol, muyenera kusamala, monga kuvala magolovesi oteteza mankhwala, magalasi ndi zovala zoteteza. Pewani kukhudzana ndi bromophenol pakhungu ndi maso, ndikuwonetsetsa kuti ntchitoyo ikuchitika pamalo olowera mpweya wabwino. Potaya zinyalala, malamulo a chilengedwe ayenera kutsatiridwa ndipo bromophenol yotsalira iyenera kutayidwa bwino. Kugwiritsa ntchito ndi kusungirako bromophenol kuyenera kutsata malamulo ndi malangizo oyenera.
