Intshayelelo
I-4-Methoxybenzophenone, eyaziwa ngokuba yi-4′-methoxybenzophenone, i-organic compound. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwekhompawundi:
Umgangatho:
I-4-Methoxybenzophenone yikristale emhlophe ukuya kumthubi kunye nevumba lebenzene. Ikhompawundi iyanyibilika kancinane emanzini kwaye inyibilika kwizinyibilikisi eziphilayo ezifana ne-ethanol, ii-ethers, kunye nezinyibilikisi ezineklorini.
Ukusetyenziswa: Inokusetyenziswa kwakhona njenge-activator yee-ketones kwaye ithatha inxaxheba kwinkqubo yokusabela.
Indlela:
Indlela esetyenziswa ngokuqhelekileyo ukulungiselela i-4-methoxybenzophenone kukusabela kwe-acetophenone nge-methanol, nge-acid-catalyzed condensation reaction, kunye ne-equation yokusabela yile:
CH3C6H5 + CH3OH → C6H5CH2CH2C(O)CH3 + H2O
Ulwazi ngoKhuseleko:
I-4-Methoxybenzophenone ayinabungozi kangako, kodwa isafuna ukuphathwa ngokukhuselekileyo. Xa udibana nolusu, kunokubangela ukucaphuka okuncinci. Ityhefu inokwenzeka ukuba ifakwe okanye ifakwe kakhulu. Ngethuba lokusetyenziswa, iiglavu kunye neeglasi zokukhusela kufuneka zigqitywe, kwaye iimeko ezifanelekileyo zokungenisa umoya kufuneka zigcinwe.
