A study of direct hydration of dihydromyrcene (DHM) with H2O to produce dihydromyrcenol (DHMOH) has been carried out using cation exchange resins as catalysts in a batch stirred-tank reactor. The effect of different parameters such as agitating speed, catalyst type, catalyst loading, molar ratio of the reactants and solvent, temperature and solvent on the conversion of DHM were investigated to obtain the optimal conditions of the reaction. The kinetics of hydration process was studied in the temperature range from 333.15 K to 353.15 K. A pseudo-homogeneous kinetics model was used to explain the reaction rate and the reaction rate constants and the reaction activation energy were determined.
