Isingeniso
I-1,3-Difluorobenzene iyinhlanganisela yezinto eziphilayo. Okulandelayo isingeniso esinemininingwane yezakhiwo, ukusetshenziswa, izindlela zokulungisa kanye nolwazi lokuphepha lwe-1,3-difluorobenzene:
Ikhwalithi:
I-1,3-Difluorobenzene iyinhlanganisela ye-organofluorine enokuqina okuphezulu kwamakhemikhali. Ayishi kodwa ihlangana nama-oxidizing agents aqinile. I-1,3-Difluorobenzene iyancibilika kuzincibilikisi ezivamile ezifana ne-ethanol, i-ether ne-chloroform, futhi ayincibiliki emanzini.
Sebenzisa:
I-1,3-difluorobenzene inenani elithile lohlelo lokusebenza ku-organic synthesis. Ingasetshenziswa njenge-reagent yokusabela ku-organic synthesis, isibonelo njenge-fluorinating reagent yezinhlanganisela ezinuka kamnandi. I-1,3-difluorobenzene ingasetshenziswa futhi ekuhlanganiseni kwezinto ezikhanyayo, ukulungiswa kwamadivayisi we-organic optoelectronic nezinye izinkambu.
Indlela:
I-1,3-I-Difluorobenzene ingalungiswa nge-fluorination ye-benzene. Izindlela zokulungiselela ezivame ukusetshenziswa yi-hydrogen fluoride njenge-agent e-fluorinating noma ukusetshenziswa kwe-ferrous fluoride complexes ukusabela kwe-fluorination.
Ulwazi Lokuphepha:
Lezi zinyathelo zokuphepha ezilandelayo kufanele zithathwe lapho usebenzisa i-1,3-difluorobenzene:
1.1,3-I-Difluorobenzene inobuthi obuthile, obungabangela ukulimala uma uthinta isikhumba, ukuhogela igesi noma ukungenwa ngephutha. Izimpahla zokuzivikela ezifanele ezifana namagilavu, izingubo zamehlo ezivikelayo, namamaski kufanele zigqokwe ngesikhathi sokusetshenziswa.
2. Gwema ukuthintana nama-oxidizing aqinile ukuze ugweme umlilo noma ukuqhuma.
3. Kufanele igcinwe endaweni eyomile, epholile futhi enomoya omuhle, kude nomlilo nezinto ezivuthayo.
5. Gwema ukuxubana namanye amakhemikhali futhi uqhelelane nezingane kanye nabantu abangazi ukuthi kuhlinzekwe kanjani.
