Isingeniso
I-2,4′-I-Dichlorobenzophenone (eyaziwa nangokuthi i-Dichlorodiphenylketone) iyinhlanganisela yezinto eziphilayo. Nazi ezinye zezakhiwo, ukusetshenziswa, izindlela zokulungiselela, nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: I-2,4′-I-Dichlorobenzophenone iyikristalu engenambala noma i-crystalline powder emhlophe.
- Ukunyibilika: I-2,4′-dichlorobenzophenone iyancibilika kuzincibilikisi zemvelo njenge-ethanol ne-dimethylformamide.
Sebenzisa:
I-2,4′-I-Dichlorobenzophenone inezinhlelo zokusebenza ezibalulekile ku-organic synthesis:
- Njenge-catalyst: ingasetshenziselwa ukusabela okuhlukahlukene kwe-organic, njengokunciphisa, i-oxidation, i-amide kanye nokusabela kokuphelelwa amandla kwamanzi.
- Njengesiphakathi: Ingasetshenziswa njengesiphakathi esibalulekile ekuhlanganiseni ezinye izinhlanganisela.
- Njengento ephilayo: ingasetshenziswa ukulungisa izinto ezithinta izithombe, odayi be-fluorescent nama-polymers.
Indlela:
I-2,4′-I-Dichlorobenzophenone ivame ukulungiswa ngokusabela kwe-dichlorobenzophenone nge-chloroacetic acid. Kunezinhlobo ezahlukene zezindlela eziqondile zokulungiselela, okuhlanganisa indlela yokusabela kwe-solvent, indlela yokuhlanganiswa kwesigaba esiqinile kanye nendlela yokuhlanganiswa kwesigaba segesi.
Ulwazi Lokuphepha:
I-2,4′-I-Dichlorobenzophenone ayinabo ubuthi obuncane kodwa kusafanele isondele ngokuqapha:
- Njengekhemikhali, ukuthintana ngqo nesikhumba, amehlo, nokuhogela uthuli lwaso kufanele kugwenywe.
- Izinyathelo zokungenisa umoya ezinhle kufanele zithathwe ngesikhathi sokusebenza ukuvimbela ukuhogela komhwamuko nothuli.
- Uma ungenwa ngephutha noma uhogele umoya, thintana nodokotela futhi uthintane nochwepheshe.
