Thermodynamic and Kinetic Study on the Catalysis of Isobornyl Acetate by a Cation Exchange Resin an Intensified Fixed-Bed Reactor

Abstract

Esterification Thermodynamic and Kinetic on acetic acid with camphene was studied systematically in an intensified fixed bed reactor at 303-323 K with anhydrous NKC-9 resin. The catalyst loading, initial molar ratio, temperature, and catalyst reusability were studied and optimized. The method of UNIFAC was applied to calculate the activity coefficient of each component for correcting the nonideality of the solution. Reaction enthalpy, entropy, and Gibbs free energy were calculated. The kinetics of camphene esterification was studied by pseudo-homogeneous model (PH model), and the fitting effect was good, which provided experimental reference and theoretical basis for the industrial production of isobornyl acetate.
