摘要

含锆的UiO-66和UiO-66- nh2是苯乙醛与甘油缩醛反应的良好非均相催化剂,反应时间短(2 h),产率高。得到了1,3-二恶烷和1,3-二恶烷的混合物,其比例可以根据使用的催化剂、固体缺失连接缺陷的数量和反应时间在2.8到4.6之间进行修改。催化剂在使用的反应条件下是稳定的,并且它们可以重复使用而不损失活性和选择性。UiO-66材料的范围用于调味工业中其他感兴趣的甘油缩醛的形成,这代表了甘油增值的有趣途径。

Zr-containing UiO-66 metal–organic frameworks as efficient heterogeneous catalysts for glycerol valorization: synthesis of hyacinth and other glyceryl acetal fragrances†

Zr-containing UiO-66 and UiO-66-NH2 are good heterogeneous catalysts for the acetalization of phenylacetaldehyde with glycerol, producing the corresponding hyacinth fragrance in high yields after short (2 h) reaction times. Mixtures of 1,3-dioxolanes and 1,3-dioxanes are obtained, whose ratios can be modified between 2.8 and 4.6 depending on the catalyst used, the amount of missing linker defects of the solid, and the reaction time. The catalysts are stable under the reaction conditions used, and they can be reused without loss of activity or selectivity. The scope of UiO-66 materials is demonstrated for the formation of other glyceryl acetals of interest for the flavoring industry, which represents an interesting route for glycerol valorization.
