実験手順
78 g of 4-acetyl-benzophenone is boiled together with 500 ml of ethanol and 200 ml of triethyl orthoformate for 5 hours. The solvent is then distilled off under reduced pressure and the residue is subjected to fractional distillation. 4-(Diethoxyacetyl)-benzophenone is obtained; b.p. 200°/67 P.
