5.  Esterification of Benzoic Acid with Propylene Glycol in an Experimental Bubble Column Reactor Part I

Authors: S. Popa, S. Boran, C. Paul and P. Borza


Abstract:

The column type reactors play a particularly important role in the chemical industry and technology, because they are successfully used in most of the industrial processes. In this work, the esterification of benzoic acid with propylene glycol into a bubble gas reactor was investigated. The esterification process in a column type reactor is dependent on several factors such as: temperature, pressure, the diameters of the inlet nozzle, the inner stirring. The effect of these paramenters on the conversion and energetic efficiency were invetigated. The formation of the reaction product was proved based on the acidity index value, IR and 1H-NMR spectra.


Keywords: bubble column reactor, esterification process, energetic efficiency
