Mawu Oyamba

M-bromophenol. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha m-bromophenol:

 

Ubwino:

Maonekedwe: M-bromophenol ndi woyera crystalline kapena crystalline powdery olimba.

Kusungunuka: Kusungunuka mu zosungunulira organic monga ethanol ndi etha, osasungunuka m'madzi.

Katundu Wamankhwala: Phenol ya M-brominated imatha kukhala oxidized pa kutentha kochepa ndipo imatha kuchepetsedwa kukhala m-bromobenzene pochepetsa othandizira.

 

Gwiritsani ntchito:

M'munda wa mankhwala ophera tizilombo: m-bromophenol itha kugwiritsidwanso ntchito ngati wapakatikati mu mankhwala ophera tizirombo muulimi.

Ntchito zina: m-bromophenol itha kugwiritsidwanso ntchito ngati zopangira zopangira organic synthesis, komanso utoto, zokutira ndi zina.

 

Njira:

M-brominated phenol imatha kupezedwa ndi p-nitrobenzene bromination. Choyamba, p-nitrobenzene imasungunuka mu sulfuric acid, kenaka bromidi ya cuprous ndi madzi amawonjezeredwa kuti apange phenol ya m-brominated kupyolera mukuchita, ndipo pamapeto pake amachotsedwa ndi alkali.

 

Zambiri Zachitetezo:

M-bromophenol ndi poizoni ndipo iyenera kupewedwa pokoka mpweya, kumeza, kapena kukhudzana ndi khungu ndi maso.

Zida zodzitetezera monga magolovesi odzitetezera, magalasi ndi zishango zakumaso ziyenera kuvalidwa pakagwiritsidwe ntchito kuti mpweya wabwino ukhale wabwino.

Posunga ndi kunyamula m-bromophenol, pewani kukhudzana ndi ma oxidants amphamvu, ma acid amphamvu ndi maziko amphamvu kuti mupewe zoopsa.
