    • A process for producing a monoalkenyl aromatic hydrocarbon which comprises alkenylating a side chain of an aromatic hydrocarbon compound having at least one hydrogen atom at the .alpha.-position of a side chain (such as o-xylene) with a conjugated diene having 4 or 5 carbon atoms in the presence of a catalyst slurry prepared by adding an aromatic hydrocarbon compound to a catalyst comprising a alkali metal and an alkali metal compound. In the aforementioned process, it is particularly effective that the catalyst slurry is prepared by adding the aromatic hydrocarbon compound after the aromatic hydrocarbon compound has been deoxygenated and dehydrated by distillation, and the catalyst slurry thus prepared is supplied to the reaction system. According to the aforementioned process, an industrially useful monoalkenyl aromatic hydrocarbon compound, such as a monoalkenylbenzene, can be produced at a high selectivity, in a high yield, and with enhanced safety and stability for a long time.
    • 一种单链烯基芳族烃的制造方法,其包括在侧链(例如邻二甲苯)的α-位上具有至少一个氢原子的芳族烃化合物的侧链与具有4或5个碳原子的共轭二烯链烯基化 在通过将芳族烃化合物加入到包含碱金属和碱金属化合物的催化剂中制备的催化剂浆料存在下进行。 在上述方法中,特别有效的是,通过在芳烃化合物已经脱氧并通过蒸馏脱水之后,通过加入芳族烃化合物制备催化剂浆料,并将由此制备的催化剂浆料供应到反应体系。 根据上述方法,工业上可用的单链烯基芳烃化合物如单烯基苯可以高选择性,高产率,长时间提高安全性和稳定性而制备。
