4-Chloro-4′-methylbenzophenone (CAS# 5395-79-9)

Isingeniso

I-4-Chloro-4′-methylbenzophenone iyinhlanganisela yezinto eziphilayo. Okulandelayo yisethulo sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha kwenhlanganisela:

Ikhwalithi:

- Ukubukeka: I-crystalline powder emhlophe

- Ukunyibilika: kuncibilika kwezinye izinyibilikisi zemvelo ezifana notshwala nama-ether, ancibilika kancane emanzini

Sebenzisa:

- Iphinde isetshenziswe njenge-Absorbent ye-UV, i-stabilizer yokukhanya, ne-photoinitiator, phakathi kwabanye.

Indlela:

- Indlela evamile yokulungiselela ukulungisa i-4-chloro-4′-methylbenzophenone ngokusabela nge-reagent ye-methylation, njenge-magnesium methyl bromide (CH3MgBr) noma i-sodium methyl bromide (CH3NaBr).

Ulwazi Lokuphepha:

- I-4-Chloro-4′-methylbenzophenone ayinabo ubuthi obuncane futhi iyingozi, kodwa kusafanele isetshenziswe ngokuphepha.

- Gwema ukuthinta isikhumba, amehlo, nemigudu yokuphefumula, futhi gqoka izinto zokuzivikela uma kunesidingo.

- Gcina izimo ezinhle zokungenisa umoya ngesikhathi sokusebenza.

- Lesi sithako siyasha emazingeni okushisa aphezulu kanye namalangabi avulekile, futhi kufanele sigcinwe kude nokushisa nomlilo.

- Imfucuza kanye nezinsalela kufanele kulahlwe ngokuhambisana nemithetho yendawo.
