Abstract: The hydration kinetics of lyral synthesis using myrac aldehyde as raw materials was studied. Reaction conditions on reaction rate constant were investigated. The optimum conditions were identified:reaction temperature 338 K, initial concentration of myrac aldehyde 0.5346mol/L and the flow rate 3.58×10-3 m/s. Kinetic data of myrac aldehyde synthesis lyral were fitted based on homogeneous reaction model. A kinetics model was gained, -rA=1.26×107CACH2Oexp(-66670/RT)-3.68×106CBexp(-57939/RT). Activation energy of the positive reaction is Ea+ 66.670 kJ/mol, and the reverse reaction is Ea- 57.939 kJ/mol. Relative deviations between the calculated values and the experimental values were all below 5%, which showed that the kinetic model could preferably describe the hydration of lyral.
