    • This invention relates to a process for making glycol ethers by reacting an olefin oxide with an alcohol over a catalyst comprising a layered double hydroxide (LDH) clay with its layered structure intact and having interlamellar anions at least some of which are metal anions or (poly)oxometallate anions. In the LDH clays, the interlamellar anions present are inorganic metal anions, oxometallate or polyoxometallate anions and include inter alia one or more of the following anions: chromium, vanadium, molybdenum and phosphorus, and (poly)oxoanions thereof. A copper-chromium hydrotalcite anionic clay or a magnesium-aluminium hydrotalcite anionic clay exchanged with (poly)oxometallate anions are preferred.
    • 本发明涉及一种通过使烯烃氧化物与醇反应的催化剂来制备二醇醚的方法,所述催化剂包含层状双层氢氧化物(LDH)粘土,其层状结构完整且具有层间阴离子,其中至少一些是金属阴离子或(聚 )氧化金属阴离子。 在LDH粘土中,存在的层间阴离子是无机金属阴离子,氧金属盐酸盐或多金属氧酸盐阴离子,尤其包括一种或多种下列阴离子:铬,钒,钼和磷及其(聚)氧代阴离子。 优选与(poly)oxometallate阴离子交换的铜 - 铬水滑石阴离子粘土或镁 - 铝水滑石阴离子粘土。
