Isingeniso

Okulandelayo ulwazi mayelana nezakhiwo zayo, ukusetshenziswa, ukulungiselela, kanye nolwazi lokuphepha: Izakhiwo: - Ukubukeka: Uketshezi olungenambala - Ukuncibilika: Incibilika kancane emanzini, incibilika kuma-organic solvents afana notshwala, ama-ether, nama-ketone. Ukusetshenziswa: Ukulungiselela: I-4-BROMO-2-FLUORO-1-VINYLBENZENE ingahlanganiswa ngezinyathelo ezilandelayo: - Faka i-ethyl 2-fluoro-4-bromobenzoate ne-N,N-dimethylformamide (DMF) esitsheni sokuphendula. - Faka inani elifanele le-triphenylphosphine (TPP) njenge-catalyst. - Yenza ukuphendula ezingeni lokushisa elifanele, ngokuvamile kudinga isikhathi eside sokuphendula. - Ngemva kokuphendula sekuqediwe, thola umkhiqizo wokugcina ngokuhlunga, ukukhipha, nokuhlanza. Ulwazi Lokuphepha: - I-4-BROMO-2-FLUORO-1-VINYLBENZENE ingase ibe nezingozi ezithile empilweni nasemvelweni. - Kufanele kuthathwe izinyathelo ezifanele zokuzivikela lapho uyisebenzisa noma uyiphatha, kuhlanganise nokugqoka amagilavu okuzivikela, izibuko zamehlo, nezingubo. - Gcina kude nezinto ezivuthayo nemithombo yokushisa okuphezulu ngesikhathi sokugcina nokuthutha, futhi ugweme ukuthintana nama-oxidizers. - Landela imithetho efanele nezinqubo zokuphepha lapho uphatha futhi ucubungula le nto. …
