Isingeniso

I-Fluorobenzyl bromide iyinhlanganisela yezinto eziphilayo. Iqinile ephuzi kuya kokuphaphathekile futhi inephunga elimnandi elinamandla.

 

I-Fluorobenzyl bromide inezinto eziningi ezibalulekile kanye nokusetshenziswa. Iyingxenye ebalulekile esetshenziswa kabanzi emkhakheni we-organic synthesis. I-Fluorobenzyl bromide ingethula amaqembu asebenzayo anomsebenzi wamakhemikhali okhethekile eringini enephunga elimnandi ngokusabela okushintshwayo, futhi ijwayele ukusetshenziswa ekulungiseni izinhlanganisela ezisebenzayo.

 

Indlela evamile yokulungiswa kwe-fluorobenzyl bromide iwukusabela i-benzyl bromide ne-anhydrous hydrofluoric acid. Kulokhu kusabela, i-hydrofluoric acid isebenza njenge-athomu ye-bromine futhi yethula i-athomu ye-fluorine.

Kuyinto ephilayo enobuthi obuthile. Ingabangela ukucasuka kanye nokulimala esikhumbeni, emehlweni, kanye nesistimu yokuphefumula. Izimpahla zokuvikela ezifanele ezifana namagilavu, izibuko, namamaski okuzivikela kudingeka zigqokwe ngesikhathi sokusebenza. Ukuchayeka isikhathi eside kumhwamuko we-flubromide kufanele kugwenywe ukuze kugwenywe ubuthi. Uma uhlangana ngephutha ne-fluorobenzyl bromide noma umhwamuko wayo, kufanele ugeze ngokushesha ngamanzi ahlanzekile futhi ufune usizo lwezokwelapha kusenesikhathi. Lapho ugcina i-fluorobenzyl bromide, kufanele ibekwe esitsheni esingashi, esingena umoya kahle futhi esingangeni moya, kude nezinto ezivuthayo nezinye izinto ezivuthayo.
