Isingeniso

Ngezansi kunolwazi mayelana nezakhiwo zayo, ukusetshenziswa kwayo, ukulungiselelwa kwayo, kanye nolwazi lokuphepha: Izakhiwo: - Ukubukeka: Uketshezi olungenambala - Ukuncibilika: Incibilika kancane emanzini, incibilika kuma-solvents e-organic njengama-alcohol, ama-ether, nama-ketone. Ukusetshenziswa: Ukulungiselelwa: Ukuhlanganiswa kwe-4-BROMO-2-FLUORO-1-VINYLBENZENE kungenziwa ngale ndlela elandelayo: - Faka i-ethyl 2-fluoro-4-bromobenzoate ne-N,N-dimethylformamide (DMF) esitsheni sokuphendula. - Faka inani elifanele le-triphenylphosphine (TPP) njenge-catalyst. - Yenza ukuphendula ngezinga lokushisa elifanele, okuvamise ukudinga isikhathi eside sokuphendula. - Ngemva kokuphendula kuqediwe, thola umkhiqizo wokugcina ngokusebenzisa i-distillation, i-extraction, nokuhlanza. Ulwazi Lokuphepha: - I-4-BROMO-2-FLUORO-1-VINYLBENZENE ingase ibe nezingozi ezithile empilweni nasemvelweni. - Izinyathelo zokuzivikela ezifanele kufanele zithathwe lapho uyisebenzisa noma uyiphatha, kuhlanganise nokugqoka amagilavu okuzivikela, izibuko zamehlo, nezingubo zokuzivikela. - Ngesikhathi sokugcina nokuthutha, gcina kude nezinto ezingavutha kanye nemithombo yokushisa okuphezulu, futhi ugweme ukuthintana nama-oxidizers. - Lapho uphatha le nto, kufanele kulandelwe imithetho efanele nezinqubo zokuphepha.
