  A process for making glycerol di-tert-butyl ethers is disclosed. In one aspect of the invention, glycerol and isobutylene react in the presence of a β-zeolite having a silicon to aluminum ratio greater than 150. In another aspect, the etherification is performed in the presence of a β-zeolite and added tert-butyl alcohol. Each process selectively provides glycerol di-tert-butyl ethers while reducing the generation of isobutylene dimers and trimers. Utilizing both aspects of the inventive process simultaneously affords a diether product mixture containing less than 5 wt. % of isobutylene oligomers.

  Catalysts with varying WO3 content on SnO2 were prepared and characterized by X-ray diffraction, in situ Raman spectroscopy, X-ray photoelectron spectroscopy and temperature programmed desorption of NH3. In situ Raman analysis reveals the presence isolated monomers and polymeric species of WO3. These catalysts were evaluated for the conversion of glycerol into value added chemicals. Etherification of glycerol with tertiary butanol and preparation of glycerol carbonate from glycerol and urea are studied over these catalysts. The catalytic activity results suggest that the glycerol conversion and selectivity depends on the morphology of WO3 which in turn is related to its content in the catalyst. The catalysts with 5 wt.% of WO3 on SnO2 resulted in high dispersion with larger number of strong acidic sites. The selectivity in the glycerol etherification is related to the nature of the catalyst and reaction time. These catalysts also exhibited high activity for synthesis of glycerol carbonate. The effect of various reaction parameters was studied to optimize the reaction conditions. The catalysts also exhibited consistent activity upon reuse.

  制备了二氧化锡上不同 WO3 含量的催化剂，并通过 X 射线衍射、原位拉曼光谱、X 射线光电子能谱和 NH3 的温度编程解吸对其进行了表征。原位拉曼分析表明，WO3 存在分离的单体和聚合体。对这些催化剂进行了评估，用于将甘油转化为高附加值化学品。在这些催化剂上研究了甘油与叔丁醇的醚化反应，以及用甘油和尿素制备碳酸甘油酯。催化活性结果表明，甘油的转化率和选择性取决于 WO3 的形态，而 WO3 的形态又与催化剂中 WO3 的含量有关。在二氧化硫上添加 5 wt.% WO3 的催化剂具有较高的分散性和较多的强酸性位点。甘油醚化的选择性与催化剂的性质和反应时间有关。这些催化剂在合成碳酸甘油酯时也表现出较高的活性。研究了各种反应参数的影响，以优化反应条件。这些催化剂在重复使用时也表现出稳定的活性。

  In this work the etherification reaction of glycerol with isobutene (IB) and tert-butyl alcohol (TBA) has been studied with the aim of preparing mixtures with high content of poly-substituted ethers. The results obtained using solid acid catalysts have shown that the reaction with IB proceeds at a high rate but the formation of undesired di-isobutene (DIB) represents a serious problem when catalysts with high density of acid sites, such as Amberlyst, are used. When using TBA as a reactant, the main problem is the formation of water that, due to thermodynamic reasons, prevents the formation of poly-substituted ethers regardless of the catalyst used. Some preliminary experiments carried out with a water permselective tubular membrane have demonstrated that the yield of poly-substituted ethers significantly increases once water was selectively removed from the reaction medium by recirculation of the gas phase.

  “摘要” 在这项工作中，研究了甘油与异丁烯（IB）和叔丁醇（TBA）的醚化反应，旨在制备高含量的多取代醚混合物。使用固体酸催化剂得到的结果表明，与 IB 的反应速率很高，但当使用具有高密度酸位的催化剂（如 Amberlyst）时，不希望的二异丁烯（DIB）的形成代表了一个严重的问题。当使用 TBA 作为反应物时，主要问题是水的形成，由于热力学原因，无论使用什么催化剂，水都会阻止多取代醚的形成。一些初步的实验使用具有水选择性的管状膜进行，证明了通过气相循环选择性地从反应介质中去除水后，多取代醚的产率显着增加。
