Isingeniso

I-Bromobenzene iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-bromobenzene:

 

Ikhwalithi:

1. Iwuketshezi olungenambala, olusobala kuya kokuphuzi ngokukhanyayo ekamelweni lokushisa.

2. Inephunga elimnandi eliyingqayizivele, futhi ayincibiliki emanzini, futhi ixubana nezinyibilikisi eziningi eziphilayo ezifana notshwala ne-ether.

3. I-Bromobenzene iyinhlanganisela ye-hydrophobic engaxutshwa yi-oxidant oxygen ne-ozone.

 

Sebenzisa:

1. Isetshenziswa kabanzi ekuphenduleni kokwenziwa kwe-organic, njenge-reagent ebalulekile kanye ne-intermediate.

2. Ingasetshenziswa futhi njengesinqamuleli somlilo lapho kwakhiwa amapulasitiki, okokunamathela kanye nemikhiqizo kagesi.

 

Indlela:

I-Bromobenzene ilungiswa kakhulu yindlela ye-ferromide. I-ayoni iqala ukusabela nge-bromine ukuze yakhe i-ferric bromide, bese i-iron bromide iphendulwa nge-benzene ukwenza i-bromobenzene. Izimo zokusabela ngokuvamile ziwukusabela kokushisa, futhi kuyadingeka ukunaka ukuphepha lapho ukusabela kwenziwa.

 

Ulwazi Lokuphepha:

1. Inobuthi obuphezulu kanye nokugqwala.

2. Ukuchayeka ku-bromobenzene kungase kubangele ukucasuka emehlweni, esikhumbeni nasemgudwini wokuphefumula womzimba womuntu, futhi kubangele ngisho nobuthi.

3. Uma usebenzisa i-bromobenzene, izinto zokuzivikela ezifanele kufanele zigqokwe, njengamagilavu, izibuko zokuphepha kanye namamaski okuzivikela.

4. Futhi qinisekisa ukuthi isetshenziswa endaweni enomoya omuhle ukuze ugweme ukuthintana isikhathi eside noma ukuhogela.

5. Uma uhlangana ne-bromobenzene ngephutha, kufanele usule ngokushesha ingxenye ethintekile ngamanzi amaningi futhi ufune usizo lwezokwelapha.
