EQUILIBRIUM THERMODYNAMICS AND MASS TRANSFER PARAMETERS ESTIMATION OF THE PRODUCTS OF SYNTHESIS OF PIPERONAL BY HIGH PERFORMANCE LIQUID CHROMATOGRAPHY
Journal Title: The Journal of Engineering and Exact Sciences - Year 2015, Vol 1, Issue 1
Abstract
The moment technique from pulse chromatography is applied to obtain information about equilibrium and mass transfer parameters in the separation of piperonal in mixture with safrole, isosafrole and terpinolene, compounds present in the synthesis of piperonal from essential oil of Piper hispidinervum C.DC (long pepper). In this paper, the adsorption and mass transfer phenomena of these compounds were studied using C18 as stationary phase, and ethanol/water 70/30 (v/v) at 35 oC as mobile phase. The values of partition equilibrium constant, mass transfer parameters and axial dispersion coefficients are obtained, and show the piperonal as less retained specie.
