通过对缩醛气相催化裂解反应的研究,根据降低催化剂功能性成分的内表面,有助于提高催化剂催化活性和选择性的思路,设计并制备了一种硅胶负载磷酸钙的结构型催化剂.在催化裂解乙醛缩二异丁醇合成乙烯基异丁基醚的反应时,与常规的磷酸钙催化剂相比,这种催化剂具有较高的催化活性和选择性,对温度的敏感性较低.并用XRD、SEM对催化剂进行了表征. Based on the research on gas phase catalytic cracking of acetal, a silica-based calcium phosphate supported structural catalyst has been designed and prepared according to the idea of ​​reducing the inner surface of the functional components of the catalyst and improving the catalytic activity and selectivity of the catalyst. Catalytic cracking of acetaldehyde diisobutyl alcohol synthesis of vinyl isobutyl ether reaction, compared with the conventional calcium phosphate catalyst, this catalyst has high catalytic activity and selectivity, low sensitivity to temperature. The catalysts were characterized by XRD and SEM.
