✦ Synopsis

A recent article by van der Vaart and van der Vaart (1991), to be referred to as V and V, described the use of an endothermic reaction to desensitize an otherwise (parametrically) sensitive tubular, pseudo-homogeneous reactor. Three sensitivity criteria used in the past were examined: I. using the relative behavior of the system trajectory and the zero isocline in the phase plane (T vs. C ) ; 11. defining a sensitive system as one for which d 2 T / d g > 0 at some point x (the axial distance along the reactor) before x,,, the point (hotspot) at which the reactor temperature attains its maximum T,,,; and 111. defining ~~ Correspondence concerning this work should be addressed to D. R. van der Vaart.
