二氢月桂烯水合动力学研究

The Kinetics Study of Direct Hydration of Dihydromyrcene

以二氧六环为溶剂,以强酸性阳离子交换树脂NKC-9为催化剂,在消除内、外扩散的影响后,考察了反应温度、催化剂浓度对二氢月桂烯水合反应的影响。采用拟均相反应机理模型关联了实验数据,关联结果良好,并得到了主反应与副反应的反应速率常数与温度的关系以及主反应与副反应的反应平衡常数与温度的关系。

With the solvent of 1,4 - dioxane and the catalyst of strongly acidic cationic exchange resin NKC - 9, the effects of reaction temperature and catalyst concentration on the hydration of dihydromyrcene were studied under the elimi- nation of the effects of internal and external mass - transfer resistances. The data was correlated by a pseudo - homogenous model and the result was satisfied. The relationship between the reaction rate constants of forward reaction and reverse reaction and temperature and the reaction equilibrium constants for both of the main reaction and side reaction were obtained.
