本文研究了国产氧化铝做a苯乙醇脱水制苯乙烯的催化剂的可能性;同时研究了过程的动力学。根据初速度与反应体系总压强的关系初步判定本反应与双活性中心参与的表面反应为控制步骤的机理模型吻合,並且进一步实验判明a苯乙醇的吸附强于苯乙烯及水,而且水的吸附极弱,从而建立了整个过程的动力学模型。 In this paper, the possibility of a catalyst for the dehydration of a-phenylethyl alcohol to styrene was investigated. The kinetics of the process was also studied. According to the relationship between the initial velocity and the total pressure of the reaction system, it is preliminarily determined that the reaction of this reaction and the surface reaction involved in the dual activity center are consistent with the mechanism model of the control step, and further experiments show that the adsorption of a phenylethyl alcohol is stronger than that of styrene and water, Very weak, thus establishing a dynamic model of the whole process.
