摘　　要：浸没循环撞击流反应器(SC ISR)的主要特点是撞击区能显著强化微观混合且存在压力波动。对于若干反应体系例如正丁醇与浓硫酸反应等,SC ISR显示出明显优于搅拌反应釜(STR)的反应动力学性能,在相同条件下,浸没循环撞击流反应器中所测的正丁醇与浓硫酸反应速率常数k比搅拌槽反应器高约10%。The major features of Submerged Circulative hnpinging Stream Reactor （SCISR） are its significantly promoted micro - mixing in the impingement zone and being of pressure fluctuations. In several practice cases, such as the reaction of n - butanol and sulphuric - acid, SCISR exhibits much better ki- netics performances than the traditional stirred tank reactors （STR）. In the same conditions, the reaction rate constant k of the reaction of n - butanol and sulphuric - acid in SC1SR is greater than that in STR by about 10%.
