| 摘 要： | 苯酮是三次采油用烷基苯磺酸盐表面活性剂的重要中间体，传统的三氯化铝作催化剂活性较高，使得副产物多难以分离．采用多聚磷酸代替三氯化铝作温和的催化剂合成了对乙基月桂苯酮，取得了很好的结果，精制产品的气相色谱纯度达93％以上．给出了产品的熔点和沸点数据，通过红外、核磁共振波谱等分析手段证明其结构正确，气质联用证明相对分子质量相吻合，并推断了多聚磷酸Friedel-Crafts酰化反应均机理。

| Abstract: | Alkylbenzenephone is a very important intermediate of alkylbenzenesulfonate surfactant for the tertiary-enhanced oil recovery.AlCl_3 is very frequently used in Friedel-Crafts reaction according to the reference.But many side reactions occurred because of its high activity.Polyphosphoric acid(PPA) is used in place of AlCl_3 as a milder catalyst,1-(4-ethylphenyl) dodecan-1-one was synthesized with the purity higher than 93%.Its melting point,boiling point were measured too.Its structure was proved to be right by IR,()~1H NMR and right relative molecular mass was testified by GC-MS.The mechanism of the Friedel-Crafts acylation reaction was also predicted. |

| Keywords: | 1-(4-ethylphenyl) dodecan-1-one Friedel-Crafts reaction acylation polyphosphoric acid |
