  TiO2–ZrO2 solid acid catalyst was prepared and applied in the catalytic acetalization and ketalization of glycerol with carbonyl compounds to produce biofuel additives. The presence of WOx promoter and TiO2 remarkably improved the catalytic activity of ZrO2. Approximately, 100% glycerol conversion was evidenced with non-bulky aliphatic aldehydes and ketones like, propanol and cyclohexanone. The physical

  摘要 制备了WO x促进的TiO 2 -ZrO 2固体酸催化剂，并将其应用于甘油与羰基化合物的催化缩醛化和缩酮化生产生物燃料添加剂。WO x助剂和TiO 2的存在显着提高了ZrO 2的催化活性。大约 100% 的甘油转化被非大体积脂肪醛和酮（如丙醇和环己酮）证明。WO x促进的TiO 2 -ZrO 2的物理表征揭示了 ZrO 2的四方晶相的较高形成，超过单斜。总表面酸度和布朗斯台德与路易斯酸性位点浓度之比分别通过 NH 3 -TPD 和吡啶化学吸附 FTIR 光谱测定。在 WO x促进的TiO 2 -ZrO 2催化剂表面上证明了明显更高浓度的路易斯酸性位点，约 213.29 μmol/gm 。催化活性研究揭示了表面路易斯酸性位点浓度与催化剂活性之间的直接相关性。这一重要观察表明路易斯酸性位点在该催化过程中的关键作用。WO x促进的TiO 2 –ZrO 2催化剂也相当稳定，在甘油与其他取代羰

  hydroalkoxylation of double bonds. A heterogeneous catalyst based on the impregnation of benign metals such as iron and bismuth on montmorillonite was used for a highly atom-economic transformation in DMC, a non-VOC solvent. The transformation allowed the formation of a large range of cyclic ethers from the corresponding unsaturated alcohols and the catalyst could be recycled several times.
