Temperature-conversion phase plane

A clear understandig of the characteristics of the various parametric sensitivity criteria reported in the literature can be best achieved by considering the following simple model, describing the temperature - conversion phase plane behavior of a pseudohomogeneous plug-flow reactor, where an exothermic irreversible n-th order reaction occurs [c.f. Morbidelli and Varma (1988)] ... 

The static behavior of the reactor can also be shown in a conversion-temperature phase plane. The static energy balance Eqn. (12.35) can be combined with the static component balance Eqn. (12.36) to give ... 

For compound 23 the uncharacterized phase, denoted as M, was found to be exhibited over a fairly wide temperature range. Ribeiro et al, found that the X-ray diffraction patterns associated with the intermediary phase were typical of a disordered smectic modification. The d spacing of 45.3 A was found to be a little bit shorter than the calculated molecular length which is consistent with the presence of a smectic A phase. As the material also exhibits a Grandjean plane texture it was concluded that the phase must be a TGB modification. However, the platelet/fan texture exhibited by the mesophase conversely suggests that a columnar ordering must be present as well,...
