本文报道了层状双氢氧化物及其分解产物的结构和组成性质对环氧丙烷醇解生成乙二醇醚的影响。在指示剂滴定结果的支持下，该反应被用作阐明这些材料中活性位点的身份的工具。对于LDHs，催化行为与其结构性质有关，因此活性位点可以合理化。然而，在其煅烧衍生物的情况下，由于活性位点的多样性，没有明显的相关性。
Studies on the effect of the structural and compositional properties of layered double hydroxides (LDHs) and their decomposition products on the ethanolysis of propylene oxide to form glycol ethers are reported. The reaction, supported by results of indicator titrations, is used as a tool for elucidating the identity of the active sites in these materials. For LDHs, the catalytic behavior relates to their structural properties and the active sites can therefore be rationalized. In the case of their calcined derivatives, however, there is no apparent correlation due to the diversity of the active sites.
