The mechanism of hydration of pinene was investigated by analyzing the main product and by-products. The hydration of Pinene was catalyzed by H2SO4. The influences of the reactant ratio, concentration of H2SO4and reaction temperature and other factors were studied. At the same time, by-products were analyzed by the GC-MS and the reaction mechanism was discussed. The results showed that the yield of terpine hydrate was over 89 % and that of 1,4-cinenle and other by-products were over 50 %, at the conditions in which temperature was 15-20 ℃ and H2SO4 concentration was 27 %. The ratio of product was related to the mechenism of hydration of pinene.
