Isingeniso

I-M-bromophenol. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-m-bromophenol:

 

Ikhwalithi:

Ukubukeka: I-M-bromophenol iyi-crystalline emhlophe noma i-crystalline powdery solid.

Ukunyibilika: kuncibilika kuzincibilikisi eziphilayo njenge-ethanol ne-ether, ezingancibiliki emanzini.

Izakhiwo zamakhemikhali: I-M-brominated phenol ingafakwa i-oxidized ekushiseni okuphansi futhi ingancishiswa ibe yi-m-bromobenzene ngama-ejenti anciphisa.

 

Sebenzisa:

Emkhakheni wezibulala-zinambuzane: i-m-bromophenol ingasetshenziswa futhi njengendawo ephakathi kwezinambuzane ukubulala izinambuzane kwezolimo.

Okunye ukusetshenziswa: i-m-bromophenol ingasetshenziswa futhi njengento eluhlaza yokusabela kwe-organic synthesis, kanye nodayi, okokumboza nezinye izinkambu.

 

Indlela:

I-M-brominated phenol ngokuvamile ingatholwa ngokuxutshwa kwe-p-nitrobenzene. Okokuqala, i-p-nitrobenzene incibilika ku-sulfuric acid, bese i-cuprous bromide kanye namanzi kwengezwa ukuze kukhiqizwe i-m-brominated phenol ngokusabela, futhi ekugcineni kuncishiswe nge-alkali.

 

Ulwazi Lokuphepha:

I-M-bromophenol inobuthi futhi kufanele igwenywe ngokuhogela, ukuyingenisa, noma ngokuthinta isikhumba namehlo.

Izinto zokuzivikela ezinjengamagilavu ​​okuzivikela, izibuko nezihlangu zobuso kufanele zigqokwe ngesikhathi sokusetshenziswa ukuze kuqinisekiswe umoya omuhle.

Lapho ugcina futhi uphatha i-m-bromophenol, gwema ukuthintana nama-oxidants aqinile, ama-asidi aqinile nezisekelo eziqinile ukuze ugweme ukusabela okuyingozi.
