摘要
采用浸渍法制备了CuCl/-γAl2O3、CuO/-γAl2O3和CuCl-CuO/γ-Al2O3催化剂,在其分别与吡啶组成的催化体系中,苯乙烯和四氯化碳发生加成反应,分析了催化剂活化温度、活性组分质量分数、反应温度、反应时间及加料顺序等对加成反应中间体1,3,3,3-四氯丙基苯收率的影响。在对甲苯磺酸-硫酸、Fe2(SO4)3.7H2O和ZnSO4等酸性催化剂存在下,1,3,3,3-四氯丙基苯水解生成肉桂酸,1,3,3,3-四氯丙基苯和肉桂酸的纯度分别可达93.0%和90.0%。
CuCl/γ-Al2 O3 ,CuO/γ-Al2 O3 and CuCl-CuO/T-Al2O3 catalysts were prepared by impregnation method. 1,3,3,3-Tetrachloropropyl benzene（1） was synthesized from the addition reaction of CCl4 and styrene in these catalyst systems as well as pyridine. Influence of activation temperatures of catalysts,mass fraction of active parts of catalysts, reaction temperature, reaction time and charging sequence on the yield of Ⅰwere discussed. The authenticate Ⅰwas hydrolyzed in sulfuric acid to give cinnamic acid with p-CH3-C6H4SO3H-H2 SO4, Fe2 （SO4） 3 · 7 H2O or ZnSO4 as catalyst. The purities of 1,3,3,3-tetrachloropropyl benzene and cinnamic acid were 93.0% and 90. 0% respectively.
