摘要

采用静态水热法合成了Me-OMS-1s(Me=Mg

Cu)分子筛催化剂

对合成的分子筛进行了X射线衍射和电感耦合等离子体发射光谱表征

并系统考察了反应温度(318~338 K)、反应时间(0.5~6 h)和催化剂用量(1.67~8.33 mg·ml-1)对Me-OMS-1s催化叔丁基过氧化氢分解制备叔丁醇反应性能的影响。研究结果表明

合成的分子筛均为钡镁锰矿型(todorokite)氧化锰;在选择的多相催化反应条件下

Me-OMS-1s均有催化叔丁基过氧化氢歧化分解的反应活性

反应物叔丁基过氧化氢具有较高的转化率

产物叔丁醇的选择性均为100%。Me-OMS-1s催化叔丁基过氧化氢歧化分解的反应活性顺序为:Cu-OMS-1 > Mg-OMS-1 > Ni-OMS-1 > Co-OMS-1。叔丁基过氧化氢的转化率随反应温度的升高、反应时间的延长和Me-OMS-1s用量的增大而显著增大。

Abstract

A series of Me-OMS-1s (Me=Mg

Cu) molecular sieves was synthesized by the static hydrothermal method. The as-synthesized Me-OMS-1s were characterized by means of XRD and AES-ICP. The effects of reaction temperature (318—338 K)

reaction time (0.5—6 h) and formal catalyst concentration (1.67—8.33 mg·ml-1) were investigated in detail on catalytic decomposition of tert-butyl hydroperoxide into tert-butyl alcohol over the as-synthesized Me-OMS-1s. The results showed that the synthetic Me-OMS-1s belonged to todorokite-type manganese oxides. All the Me-OMS-1 catalysts bore the activity for the catalytic disproportionation decomposition of tert-butyl hydroperoxide under the selected heterogeneous catalytic reaction conditions. The conversion of the reactant tert-butyl hydroperoxide under various reaction conditions was found to be high and the selectivity towards the product tert-butyl alcohol was 100%. The activity of Me-OMS-1s followed the order of: Cu-OMS-1 > Mg-OMS-1 > Ni-OMS-1 > Co-OMS-1. The conversion level of tert-butyl hydroperoxide was markedly enhanced with increasing reaction temperature

contact time and formal Me-OMS-1 concentration.
