性质:也称连续活塞式流动法(continuous plug-flow method)。对于一级反应,可推导出k=(v/Ax)1n{[A]/[A]0},式中v为流速(dm3/s),A为管状反应器(tubular reactor)横截面积,x为离混合室的距离。与一级反应动力学方程相比,k=t-1ln{[A]/[A]0},反应时间t之测量转化为x之测量。这类方法应满足两个条件:(1)达到充分混合的时间极短,即t混合<<t反应;(2)流动管反应器(flow-tube reactor)中无纵向的扩散、对流,即管中任一截面各部位的成分是一致的。本方法解决了快速反应难于把握反应时间的问题。缺点是要消耗大量反应液;受混合时间及效率的制约,一般只能测量毫秒(ms)量级的反应;反应管径细,以致测量信号弱。针对这些缺点,已发展出许多改进的技术。
