Isingeniso

 

Ikhwalithi:

I-Bromophenol iyi-crystalline eqinile engenambala noma emhlophe enephunga elingavamile le-phenolic. Iyancibilika kuma-solvents ephilayo ekamelweni lokushisa futhi incibilika kancane emanzini. I-Bromophenol iyinhlanganisela ye-asidi ebuthakathaka engase isuswe yizisekelo ezifana ne-sodium hydroxide. Ingabola uma ishisa.

 

Sebenzisa:

I-Bromophenol ivame ukusetshenziswa njengento ebalulekile eluhlaza futhi ephakathi ku-organic synthesis. I-Bromophenol ingasetshenziswa futhi njengesibulala-magciwane ukubulala amagciwane.

 

Indlela:

Kunezindlela ezimbili eziyinhloko zokulungiselela i-bromophenol. Enye ilungiswa ukusabela kwe-benzene bromide ne-sodium hydroxide. Enye ilungiswa nge-resorcinol nge-bromination. Indlela ethize yokulungiselela ingakhethwa ngokwezidingo zakho.

 

Ulwazi Lokuphepha:

I-Bromophenol iyikhemikhali enobuthi, futhi ukuchayeka noma ukuhogela kungase kube nemiphumela emibi empilweni yomuntu. Lapho uphatha i-bromophenol, kufanele kuthathwe izinyathelo zokuphepha ezidingekayo, njengokugqoka amagilavu ​​okuvikela amakhemikhali, izibuko nezingubo zokuzivikela. Gwema ukuthintana ne-bromophenol esikhumbeni nasemasweni, futhi uqinisekise ukuthi ukuhlinzwa kwenziwa endaweni enomoya omuhle. Lapho kulahlwa imfucuza, imithethonqubo yezemvelo kufanele ilandelwe futhi i-bromophenol esele kufanele ilahlwe kahle. Ukusetshenziswa nokugcinwa kwe-bromophenol kufanele kuhambisane nemithethonqubo nemihlahlandlela efanele.
