摘  要:
为解决涉及一些较大分子的反应之固体酸催化问题,以价格便宜的硅酸钠为主要原料合成了磺酸基官能化介孔材料MSU,并采用固体核磁共振(SSNMR)等技术研究了所合成材料(MSU-SO3H)的结构和酸性.结果表明,合成的磺酸基官能化的MSU具有规整的介孔结构,其总体酸性略弱于微孔分子筛HZSM-5.

摘  要:
Sulfonic group functionalized mesoporous materials with MSU structure were synthesized by using the cheap sodium silicate as a main raw material.Furthermore,their structure and acidity were characterized in detail using multinuclear NMR technique in combination with other approaches such as XRD,N2 adsorption and desorption.Our characterization results indicate that functionalized MSU-SO3H materials with well-ordered mesostructure have been successfully synthesized and the materials have acid strength slightly weaker than that of microporous zeolite HZSM-5.
