Isingeniso

I-2-Bromobutane iyi-alkane ye-halide. Okulandelayo yisingeniso kwezinye zezakhiwo zayo, ukusetshenziswa, izindlela zokukhiqiza, kanye nolwazi lokuphepha:

 

Ikhwalithi:

- Ukubukeka: Uketshezi olungenambala

- Ukunyibilika: Kuncibilika kuzincibilikisi zemvelo, ezingancibiliki emanzini

 

Sebenzisa:

- I-2-Bromobutane, njenge-bromoalkanoid, ivamise ukusetshenziswa ekuphenduleni kwe-organic synthesis njengendawo ephakathi yesandiso se-carbon chain, ukwethulwa kwama-athomu e-halogen, kanye nokulungiswa kwezinye izinhlanganisela eziphilayo.

- I-2-Bromobutane ingasetshenziswa futhi njengesengezo embotsheni, iglues kanye nezimboni zenjoloba.

 

Indlela:

- I-2-Bromobutane ingalungiswa ngokuphendula i-butane nge-bromine. Ukusabela kungenziwa ngaphansi kwezimo zokukhanya noma ngaphansi kokushisa.

 

Ulwazi Lokuphepha:

- I-2-Bromobutane iyacasula emehlweni, isikhumba, kanye nendlela yokuphefumula futhi ingabangela ukusha kwesikhumba nokulimala kwamehlo.

- Ukuhogela umoya kakhulu kungabangela isiyezi, ukuphefumula kanzima, nokucindezeleka kwesimiso sezinzwa.

- Gqoka okokuvikela okufanelekile njengezingubo zamehlo ezivikelayo, amagilavu ​​nokuvikela ukuphefumula lapho usebenzisa i-2-bromobutane.

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
