After internal and external diffusion was eliminated, the kinetics of hydration of Myrac Aldehyde was studied in a batch stirred reactor with isopropyl alcohol as solvent and cation exchange resin as catalyst. The effects of agitation speed, catalyst particle size，temperature of reaction and catalyst concentration on the reaction rate of hydration reaction were studied. The kinetics data of hydration reaction were fitted by LHHW kinetics model. Preexponential factors and reaction activation energy were fitted by Arrhenius equation. The forward and reverse preexponential factors were 0.090 46 mol/(g•s) and 5.317 40 mol/(g•s), respectively. The forward and reverse reaction activation energy were 1.724 7×10 ⁴ J/mol and 3.391 2×10 ⁴ J/mol, respectively.
