The analysis of the dynamic behavior of a continuous stirred tank reactor with a fluorescent tracer has indicated that the short‐circuit of a fraction of the liquid feed constitutes the only non‐ideality in this case. There is no dead space or piston flow in the reactor when the density difference is zero. The variation of the transfer function time constants was also studied as a first approximation, in a reactor with a density difference between the liquid feed and the reactor contents. This had led to the determination of an ideality criterion which includes the main causes of the non‐ideal mixing. The fluorescent tracer technique has permitted the isolation of the effects of physical parameters on the degree of short‐circuit from the effects on other causes of non‐ideal mixing.
