用途有機合成原料。香料原料。
使用1,3-Diphenylacetone is used in the aldol condensation reaction with benzil (a dicarbonyl) and base to create tetraphenylcyclopentadienone.
製造方法By heating α,α’-phenyl benzyl ethylene glycol or α,α’-phenyl benzyl ethylene oxide in the presence of diluted H2SO4 or ZnCl2; also by dry distillation of phenylacetate and magnesium chloride (C6H5CH2COOMgCl) or other salts of phenylacetic acid.
純化方法Fractionally crystallise it from its melt, then crystallise it from pet ether. Store it in the dark. [Beilstein 7 IV 1420.]
