摘要

通过在磷酸钛框架中加入 5- 氨基水杨酸（5-ASA），我们开发出一种合成高酸性微孔杂化磷酸钛材料（H-TiPOx）的新策略。这种新型 H-TiPOx 可用作布氏酸催化剂，其总表面酸度高达 5.9 mmol g-1，可高效催化丰富的生物质衍生甘油缩醛为索酮醛，选择性超过 99%。

A new microporous organic-inorganic hybrid titanium phosphate for selective acetalization of glycerol

We developed a novel strategy for synthesizing highly acidic microporous hybrid titanium phosphate material (H-TiPOx) by incorporating 5-aminosalicylic acid (5-ASA) in the titanium phosphate framework. This new H-TiPOx serves as Brønsted acid catalyst, exhibiting remarkable total surface acidity of 5.9 mmol g-1 and it efficiently catalyzes the acetalization of abundant biomass derived glycerol to solketal with over 99% selectivity.
