4-Valeroylbiphenyl (CAS# 42916-73-4)

Isingeniso

I-Bifenpentanone, eyaziwa nangokuthi i-diphenopylacetone, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-bifenpentanone:

Ikhwalithi:

- Ukubukeka: I-Bifenpentone iyi-crystalline eqinile engenambala noma ephuzi.

- Ukunyibilika: Kuncibilika kuzincibilikisi eziningi eziphilayo, njengotshwala nama-ether, futhi kuncibilika kancane emanzini.

- Izakhiwo zamakhemikhali: I-Bifenpentone inezici zokunciphisa ezinamandla, futhi njengenhlanganisela esebenzayo, ingabamba iqhaza ekuphenduleni kwamakhemikhali okuhlukahlukene.

Sebenzisa:

Indlela:

Kunezindlela eziningana zokulungiselela i-bifenpentanone, futhi izindlela ezivame ukusetshenziswa zihlanganisa:

- I-Benzophenone ihlangana ne-acetophenone ngaphansi kwezimo ezine-asidi ukuze yakhe i-bifenpentanone.

- Ebukhoneni be-sodium oxychloroxysulfate, i-benzophenone ne-acetopyl bromoethylketone zithola ukusabela kwe-etherification ngaphansi kwezimo ze-alkali ukuze zithole i-bifenpentanone.

Ulwazi Lokuphepha:

I-Bifenpentone ngokuvamile iphephile uma kuqhathaniswa ngaphansi kwezimo ezijwayelekile zokusetshenziswa, kodwa okulandelayo kusafanele kuqashelwe:

- Gwema ukuthinta isikhumba namehlo, futhi gqoka izinto zokuzivikela ezifanele uma uzisebenzisa.

- Gwema ukuthintana nezinto ezivuthayo kanye nama-oxidants lapho uwagcina ukuvikela izingozi zomlilo neziqhumane.

- Kufanele kuqashelwe ukuthi kungene umoya ngesikhathi sokusetshenziswa nokugcinwa ukuze kugwenywe ukuhogela umhwamuko wawo.

- Uma uhogela umoya ngephutha noma ukuchayeka ku-bifenpentanone, geza isikhumba sakho ngokushesha futhi ufune usizo lwezokwelapha.
