摘要

在低酸度硫酸体系中

以P123(EO20PO70EO20)为模板剂水热法一步合成硫酸化锆掺杂PHTS固体酸催化剂(SO42-/Zr-PHTS)

利用XRD、TEM、N2吸附-脱附以及NH3-TPD、Py-FTIR等手段对其进行表征。结果表明

SO42-/Zr-PHTS具有有序的六方相介孔结构

具有以L酸为主的弱、中强度的酸性中心;随着硅锆摩尔比的增加

其酸量逐渐减少

比表面积逐渐增加

孔容、孔径无显著变化。SO42-/Zr-PHTS在催化四氢呋喃聚合中表现出良好的反应性能

推测固体酸的表面酸性和孔结构决定着催化四氢呋喃聚合的反应性能。

Abstract

Mesoporous sulfated Zr-PHTS(SO42-/Zr-PHTS)solid acid was prepared by using P123(EO20PO70EO20)as a structure directing agent via the one-pot hydrothermal process in lower concentration sulfuric acid solution.These prepared samples were characterized by powder X-ray diffraction(XRD)

TEM

N2 sorption isotherms

Py-FTIR spectra

and NH3-TPD.The characterization results showed that the obtained samples possessed well-ordered hexagonal mesostructure

and all the samples had weak and medium acidity dominated by Lewis acid sites according to the analysis of pyridine adsorption and NH3-TPD.With the increase of Si/Zr molar ratio

specific surface areas relatively little varied and acidity was obviously reduced

but pore volume and pore diameter were not severely affected.In addition

the SO42-/Zr-PHTS catalyst showed good performance in the THF polymerization reaction

and such result could be related to the mesoporous structure and surface acidity.
