Heat and Mass Transfer Limitations in Esterification of Propionic Acid over Ion exchange resin

In heterogeneous synergist responses the warmth and mass exchange assume anindispensable part in influencing the rate of a response. Mass exchange confinements incorporate both the inner and outside dispersion of segments into and out of the impetus while warm exchange confinements incorporate whether the response occurring is isothermal in nature and to discover most extreme temperature inside the impetus molecule throughout response. In the present investigation of inherent rates of reaction both the dissemination component ought to be insignificant before the active catalyst investigations. Esterification of propionic acid over Indion 190 utilizing n-butanol as an entrainer was studied in a batch reactor. Considering the order of the esterification reaction to be one and the inner and outer dissemination is studied by Weisz Prater and Mears criteria. Temperature contrast (363 to 413OK) with in the impetus molecule calculated to check the effect of heat transfer. Keywords - Heterogeneous synergist,Indion-190, weisz prater, mears criteria.
