The action of polyphosphoricacid on acetophenone produces two crystalline yellow hydrocarbons (A and B) of the formula C32H24; other products isolated are benzoic acid, dypnone, and a yellow substance (C) melting above 300 deg . The lower-melting yellow hydrocarbon (A) is isomerized to a colorless hydrocarbon (D). Studies of the reactions and spectra of A and D are made and structures are suggested
多磷酸对苯乙酮的作用产生两种结晶黄色烃(A 和 B),分子式为 C32H24;分离出的其他产品是苯甲酸、dypnone 和黄色物质 (C),熔点高于 300 度。低熔点黄色烃(A)异构化为无色烃(D)。对 A 和 D 的反应和光谱进行了研究,并建议了这些碳氢化合物的结构。
