Intshayelelo
I-4,4'-Dimethoxybenzophenone, eyaziwa nangokuthi i-DMPK okanye i-Benzilideneacetone dimethyl acetal, i-organic compound. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwale khompawundi:
Umgangatho:
I-4,4′-I-Dimethoxybenzophenone lulwelo olungenambala ukuya kumthubi oluluthuthu olunevumba lebenzene. Iyatsha, inoxinaniso oluphezulu, kwaye inyibilika kwizinyibilikisi eziqhelekileyo ze-organic ezifana ne-ethanol, ii-ethers, kunye nee-ketones. Ayizinzanga emoyeni nasekukhanyeni kwaye inokungena kwi-oxidation reactions.
Sebenzisa:
I-4,4′-dimethoxybenzophenone isetyenziswa rhoqo njenge-catalyst okanye i-reagent kwi-organic synthesis kwaye inomsebenzi ophezulu. Kwi-organic synthesis, ingasetyenziselwa ukulungiswa kwe-aldehydes, i-ketones, njl.
Indlela:
Indlela yokulungiselela i-4,4′-dimethoxybenzophenone inokufezekiswa ngokuphendula kwe-condensation ye-dimethoxybenzosilane kunye ne-benzophenone. I-Dimethoxybenzosilane iphendulwa nge-sodium borohydride ukuze ifumane i-boranol, ize ixutywe nge-benzophenone ukuze ifumane i-4,4′-dimethoxybenzophenone.
Ulwazi ngoKhuseleko:
I-4,4′-I-Dimethoxybenzophenone iyacaphukisa ulusu kwaye inokubangela ukucaphuka kwamehlo kunye nomgudu wokuphefumula. Amanyathelo afanelekileyo okukhusela afana neeglavu, iiglavu, kunye nezixhobo zokuphefumla kufuneka zinxitywe ngexesha lokuphatha kunye nokusetyenziswa. Ngexesha lokugcinwa, kufuneka igcinwe kwindawo epholileyo, eyomileyo, kude nokucima kunye ne-oxidants. Nceda ulandele iinkqubo zokusebenza ezikhuselekileyo kwaye ulandele yonke imimiselo efanelekileyo kunye neemfuno. Kwimeko yeengozi, amanyathelo afanelekileyo kaxakeka kufuneka athathwe ngokukhawuleza.
