采用溶胶-凝胶法制备了一系列不同摩尔比的介孔酸碱双功能Zr/B复合氧化物，并将其用于乙醇催化乙酰丙酸乙酯（EL）转化为γ-戊内酯（GVL）。通过多种技术对合成材料的形态结构和理化特性进行了鉴定。当使用Zr 1B 1时，从EL在2-丙醇中获得88.5%的高GVL产率。中毒实验表明，酸碱中心在EL合成GVL过程中起协同作用。此外，催化剂可以重复使用几次，而不会显着损失其催化活性。(C)2016年韩国工业与工程化学学会。Elsevier B. V.出版，保留所有权利。
A series of mesoporous acid-base bifunctional Zr/B mixed oxides with different molar ratios were prepared by a sol-gel method, and developed for conversion of ethyl levulinate (EL) to gamma-valerolactone (GVL) by using alcohol as hydrogen source. The morphological structures and physico-chemical characteristics of the synthesized materials were identified by various techniques. A high GVL yield of 88.5% was achieved from EL in 2-propanol when Zr1B1 was used. And acid-base sites played a synergic role in synthesizing GVL from EL as evident by poisoning experiments. Furthermore, the catalyst could be reused several times without significant loss of its catalytic activity. (C) 2016 The Korean Society of Industrial and Engineering Chemistry.
