Isingeniso
I-4,4′-Dimethoxybenzophenone, eyaziwa nangokuthi i-DMPK noma i-Benzilideneacetone dimethyl acetal, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwale nhlanganisela:
Ikhwalithi:
I-4,4′-I-Dimethoxybenzophenone iwuketshezi olungenambala ukuya kokuphuzi okuphaphathekile olunephunga elimnandi le-benzene. Iyakwazi ukuvutha, inokuminyana okuphezulu, futhi incibilika kuzincibilikisi ezivamile ezifana ne-ethanol, i-ethers, nama-ketone. Ayizinzile emoyeni nasekukhanyeni futhi ingabhekana nokusabela kwe-oxidation.
Sebenzisa:
I-4,4′-dimethoxybenzophenone ivame ukusetshenziswa njenge-catalyst noma i-reagent ku-organic synthesis futhi inomsebenzi ophezulu. Ku-organic synthesis, ingasetshenziswa ekulungiseleleni ama-aldehydes, ama-ketones, njll.
Indlela:
Indlela yokulungiselela ye-4,4′-dimethoxybenzophenone ingafinyelelwa ngokusabela kwe-condensation ye-dimethoxybenzosilane ne-benzophenone. I-Dimethoxybenzosilane isabela nge-sodium borohydride ukuze ithole i-boranol, bese ifinyezwa nge-benzophenone ukuze ithole i-4,4′-dimethoxybenzophenone.
Ulwazi Lokuphepha:
I-4,4′-I-Dimethoxybenzophenone iyacasula esikhumbeni futhi ingase ibangele ukucasuka kwamehlo nendlela yokuphefumula. Izinyathelo zokuzivikela ezifanele ezifana namagilavu, izibuko, nama-respirators kufanele zigqokwe ngesikhathi sokuphatha nokusebenzisa. Ngesikhathi sokugcina, kufanele igcinwe endaweni epholile, eyomile, kude nokushisa kanye nama-oxidants. Sicela ulandele izinqubo zokusebenza eziphephile futhi ulandele yonke imithetho nezidingo ezifanele. Uma kwenzeka izingozi, izinyathelo ezifanele eziphuthumayo kufanele zithathwe ngokushesha.
