The effect of the acid–base characteristics of M-Si oxide systems (M: Mg, Zr, La), including those doped with silver, on their catalytic properties during the conversion of ethanol and an ethanol–water mixture to produce 1,3-butadiene (BD) is described. The highest yield of BD is obtained in the presence of the Ag/Zr-Si catalyst, which is characterized by the predominance of Lewis acid sites on its surface.

掺银 M-Si 氧化物体系 (M: Mg, Zr, La) 的组成对其催化乙醇转化为 1,3-丁二烯的性能的影响

M-Si 氧化物体系（M：Mg、Zr、La）的酸碱特性对它们在乙醇和乙醇-水混合物转化为 1,3 时的催化性能的影响，包括那些掺杂银的描述了-丁二烯 (BD)。在 Ag/Zr-Si 催化剂存在下可获得最高的 BD 产率，其特征在于其表面路易斯酸位点占优势。
