在298 K和150 mbar D2压力下，利用总中子散射研究了3wt%铂负载于高度有序介孔氧化硅（MCM-41）上的甲苯-d8加氢生成甲基环己烷-d14的反应。详细的动力学信息表明，液体重组孔内是整个过程中最慢的步骤。另外，将结果与在250毫巴D2压力下进行的反应以及与在150毫巴下使用D2的甲苯-h8氢化进行比较。
Total neutron scattering has been used to follow the hydrogenation of toluene-d8 to methylcyclohexane-d14 over 3 wt% platinum supported on highly ordered mesoporous silica (MCM-41) at 298 K and under 150 mbar D2 pressure. The detailed kinetic information so revealed indicates that liquid reorganisation inside pores is the slowest step of the whole process. Additionally, the results were compared with the reaction performed under 250 mbar D2 pressure as well as with toluene-h8 hydrogenation using D2 at 150 mbar.
