Isingeniso

I-Benzyl bromide iyinhlanganisela ye-organic enefomula yamakhemikhali ethi C7H7Br. Nansi eminye imininingwane mayelana nezakhiwo, ukusetshenziswa, izindlela zokulungiselela nokuphepha kwe-benzyl bromide:

 

Ikhwalithi:

I-Benzyl bromide iwuketshezi olungenambala olunephunga elimnandi ekamelweni lokushisa. Ukuminyana kwayo kungu-1.44g/mLat 20 °C, indawo yayo yokubilisa ingu-198-199 °C(lit.), kanti indawo yayo yokuncibilika ingu -3 °C. Ingancibilika kuzincibilikisi eziningi eziphilayo futhi ayincibiliki emanzini.

 

Sebenzisa:

I-Benzyl bromide inokusetshenziswa okuhlukahlukene. Ivame ukusetshenziswa ku-organic synthesis njenge-reagent yokusabela. Ingasetshenziswa ekulungiseni ama-esters, ama-ethers, ama-acid chloride, ama-ether ketones, nezinye izinhlanganisela eziphilayo. Ngaphezu kwalokho, i-benzyl bromide iphinde isetshenziswe njenge-catalyst yenkukhu, i-stabilizer yokukhanya, i-resin yokwelapha i-resin, kanye ne-flame retardant ukulungiselela.

 

Indlela:

I-Benzyl bromide ingalungiswa ngokusabela kwe-benzyl bromide ne-bromine ngaphansi kwezimo ze-alkali. Isinyathelo esiqondile ukungeza i-bromine ku-benzyl bromide, bese wengeza i-alkali (njenge-sodium hydroxide) ukuze uthole i-benzyl bromide ngemva kokusabela.

 

Ulwazi Lokuphepha:

I-Benzyl bromide iyinhlanganisela yezinto eziphilayo ezinobuthi obuthile. Inomphumela ocasulayo emehlweni, esikhumbeni, nasendleleni yokuphefumula, ngakho-ke kufanele kuqashelwe uma usebenzisa izinto zokuzivikela ezifana namagilavu, izibuko, nezihlangu zobuso lapho uthintwa. Ukwengeza, i-benzyl bromide nayo idala ingozi evuthayo futhi kufanele igwenywe ekuxhumaneni nezinto ezivuthayo futhi igcinwe kude namalangabi avulekile. Lapho ugcina futhi uphatha i-benzyl bromide, landela izinqubo ezifanele zokusebenza eziphephile futhi uyigcine endaweni ephephile futhi ugweme ukuyixuba namanye amakhemikhali.
