  摘要：

  本发明公开了一种甘油缩醛(酮)醚及其合成方法，涉及化工合成技术领域。本发明公开的甘油缩醛(酮)醚是以甘油为原料将环缩醛(酮)和醚两种官能团整合到一个分子中，这种甘油缩醛(酮)醚可以提高单位燃油添加剂的使用效率。公开的合成方法中，有两条合成路线，可以先进行醚化再进行缩醛(酮)化，也可以先进行缩醛(酮)化再进行醚化。其中，醚化反应是原子经济反应；缩醛(酮)化反应的副产物只有一分子水，方法绿色环保、效率高；产物中甘油缩醛(酮)醚的收率高，最高达99％；使用固体酸催化剂，清洁，高效，可以回收利用，极大地降低了成本，工业化价值高。

  hectorite and FeOx-pillared taeniolite) were synthesized by the intercalation of FeCl3 into clay interlayers and calcination. The synthesized catalysts were exploited for conversion of epoxides furnishing acetonides in good to quantitative yields with short time under mild conditions. The catalysts could be recovered and reused up to five times without appreciable loss of activity.

  The present invention describes the use and production of a solketal ether compound of formula (I), in particular solketal-ter-amyl-ether (STAE), in diesel fuels, gasoline, and rapeseed biodiesel, with 5 which the limited solubility of the fuel additive solketal and STBE is significantly increased and whereby products such as glycerine, acetone and light naphtha can be recycled to afford solketal ethers. These improvements are achieved by a) the production of 2,2-dimethyl-4- hydroxymethyl-l,3-dioxolane (solketal) from glycerine and acetone and b) by reacting the 2,2- dimethyl-4- hydroxymethyl-l,3-dioxolane produced in step a), or obtained in any other way, with certain alkene compounds in order to etherify the remaining OH group.

  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。
