DSA-1催化α-蒎烯三相水合的表面反应动力学

Study on the Surface Reaction Kinetics of Three-phase Hydration of αPinene on DSA1 Catalyst

研究了以二氧六环作溶剂时α－蒎烯在ＤＳＡ－１固体酸催化剂上“液－液－固”三相水合制α－松油醇中并行和串行网联的复杂反应动力学．发现反应体系中的吸附服从理想表面吸附模型，表面反应为速率控制步骤，反应动力学方程的拟合表明。

The kinetics of parallel and consecutive network reaction in the “liquidliquidsolid” threephase catalytic hydration of αpinene on porous sulphonic acid resin DSA1 by dioxane as solvent was studied for preparation of αterpineol. It is found that the adsorption in the reaction system is in keeping with Langmuir model and the surface reaction of adsorbed specise is rate controlling step. It is indicated that the hydration of αpinene on DSA1 catalyst proceed on LangmuirHinshelwood mechanism by modelling the kinetics equation.
