Isingeniso
I-3-Bromo-4-fluorobenzaldehyde iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwale nhlanganisela:
Ikhwalithi:
- Ukubukeka: I-3-Bromo-4-fluorobenzaldehyde iqinile noma iwuketshezi engenambala ukuya kokuphuzi ngokukhanyayo.
- Iphunga: Inephunga elingavamile.
- Ukunyibilika: I-3-Bromo-4-fluorobenzaldehyde iyancibilika ku-ethanol ne-acetone, kodwa ayincibiliki kancane emanzini.
Sebenzisa:
- Ukuhlanganiswa kwamakhemikhali: I-3-bromo-4-fluorobenzaldehyde ingasetshenziswa njengento ebalulekile ekuhlanganiseni kwezinto eziphilayo ukuze kulungiswe izinhlanganisela ezihlukahlukene zezinto eziphilayo.
- Ezolimo: Inhlanganisela isetshenziswa njengesibulala-zinambuzane nesibulala-sikhunta kwezolimo futhi inemiphumela emihle yokubulala izinambuzane kanye nesikhunta.
Indlela:
- Ukulungiswa kwe-3-bromo-4-fluorobenzaldehyde kuvame ukwenziwa yi-fluorination kanye nokusabela kwe-bromination. Indlela evamile ukusabela ku-4-fluorobenzaldehyde nge-bromine ukuze uthole umkhiqizo oqondiwe.
Ulwazi Lokuphepha:
- I-3-Bromo-4-fluorobenzaldehyde iyikhemikhali, sicela unakekele izinyathelo zokuphepha ezilandelayo lapho uphatha futhi ugcina:
- Gwema ukuthinta isikhumba namehlo. Uma kwenzeka ukuthintana ngephutha, hlambulula ngokushesha ngamanzi amaningi;
- Gwema ukuhogela umhwamuko noma uthuli lwawo. Izimo zokungenisa umoya ezanele zidinga ukuhlinzekwa ngesikhathi sokusebenza;
- Gwema ukuthintana nezinto ezivuthayo;
- Gcina endaweni eyomile, epholile, enomoya omuhle;
- Naka izinto zokuzivikela ezifanele (isb. Gqoka izingubo zamehlo ezivikelayo, amagilavu okuzivikela, njll.);
- Uma ungaphathekile kahle noma uhogele amanzi amaningi, funa usizo lwezempilo ngokushesha. Sicela ubheke amaphepha edatha okuphepha afanelekile kanye nemithetho neziqondiso ukuze uthole imininingwane eyengeziwe.
