Isingeniso

I-O-bromobenzoyl chloride yaziwa nangokuthi i-2-bromobenzoyl chloride. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:

 

Ikhwalithi:

- Ukubukeka: I-O-bromobenzoyl chloride iwuketshezi olungenambala noma uketshezi oluphuzi.

- Ukunyibilika: Incibilika kancane emanzini, incibilika kakhulu kuzincibilikisi zemvelo njenge-ether, i-methanol ne-methylene chloride.

- Ukusebenza kabusha: I-O-bromobenzoyl chloride iyinhlanganisela ye-acyl chloride ethambekele ekuphenduleni esikhundleni se-acyl.

 

Sebenzisa:

- I-O-bromobenzoyl chloride ivame ukusetshenziswa ekuphenduleni kwe-acyl chlorination ku-organic synthesis yokwethulwa kwamaqembu e-acyl.

- Kokunye ukuhlanganiswa kwe-organic, ingasetshenziswa njenge-ejenti evuvukalayo, i-ejenti yokunciphisa noma i-oxidizing.

 

Indlela:

I-O-bromobenzoyl chloride ivamise ukulungiselelwa ukusabela kwe-bromination kwe-o-bromobenzoyl chloride. Izinyathelo eziqondile zimi kanje:

Okokuqala, i-o-bromobenzophenone isabela ne-bromine ngaphansi kwezimo ezine-asidi ukukhiqiza i-o-bromobenzoic acid.

I-o-bromobenzoic acid bese isabela nge-phosphoryl chloride (POCl₃) ukukhiqiza i-o-bromobenzoyl chloride.

 

Ulwazi Lokuphepha:

- I-O-bromobenzoyl chloride iyacasula futhi kufanele igwenywe ukuthintana nesikhumba, amehlo kanye nomgudu wokuphefumula.

- Gqoka amagilavu ​​okuzivikela, izibuko nezingubo zokuzivikela lapho usebenzisa.

- Gwema ukuthintana nama-oxidizing aqinile noma ama-alkali aqinile, okungase kubangele ukusabela okuyingozi.

- Imfucuza kanye nezincibilikisi kufanele kulahlwe ngendlela efanele ngesikhathi sokusebenza futhi kufanele kuthathwe izinyathelo ezifanele zokuphepha zelabhorethri.
