Isingeniso

I-2-Bromopropionyl bromide iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2-bromopropionyl bromide:

 

Ikhwalithi:

- Ukubukeka: I-2-Bromopropionyl bromide iwuketshezi olungenambala ukuya kokuphuzi.

- Ukunyibilika: I-2-Bromopropionyl bromide ayincibiliki emanzini, kodwa incibilika kwezinye izinyibilikisi eziphilayo njenge-ethanol ne-ether.

- Ukusebenza kabusha: I-2-Bromopropionyl bromide ine-electrophilicity ephezulu futhi ingabhekana nokusabela okushintshwayo ngama-nucleophile.

 

Sebenzisa:

- Kulabhorethri nezimboni, i-2-bromopropionyl bromide ivamise ukusetshenziswa njenge-organic synthesis reagent yokuhlanganiswa kwezinye izinhlanganisela eziphilayo.

- Ingasetshenziswa ekulungiseleleni ama-ketones, ama-amide, nama-ester compounds.

 

Indlela:

- Ukulungiswa kwe-2-bromopropionyl bromide kungatholwa ngokusabela kwe-2-bromopropionic acid nge-bromide yesiliva. Ukusabela ngokuvamile kwenziwa ezimeni anhydrous.

 

Ulwazi Lokuphepha:

- I-2-Bromopropionyl bromide iyinto edlayo engabangela ukusha lapho ithinta isikhumba namehlo, futhi kufanele isetshenziswe nezinto zokuzivikela.

- Uma usebenzisa futhi ugcina, ukuthintana nama-oxidants nama-alkali aqinile kufanele kugwenywe ukuze kugwenywe ukusabela okuyingozi.
