摘要： 用SETARAM热流式量热计测定了环己烯和2-甲基戊烯-1于室温下在NaY、CaY、R_EY和HY等几种分子筛上的微分吸附热。我们又用Benson基团加合法计算得到了生成仲碳离子和叔碳离子时的吸附热。根据实验测得的于不同吸附量时环己烯和2-甲基戊烯-1的吸附热之差值, 对它们在上述几种Y型分子筛上的吸附机理进行了讨论。

Abstract: By using SETARAM heat-flow calorimeter the differential heats of adsorption for cyclohexene and 2-methyl-pentene-1 on NaY, CaY, R_EY and HY zeolites at ambient temperature have been measured. By means of Benson's method for the estimation of thermochemical data, the heats of adsorption for tertiary and secondary carbonium ions have been obtained. According to the differnce between heats of adsorption for cyclohexene and 2-methyl-pentene-1 at the same adsorption amounts the adsorption mechanism for cyclohexene and 2-methyl-pentene-1 on the zeolites has been discussed.
