| 摘 要： | 采用共价接枝法, 以氨丙基-三乙氧基硅烷为氨源, 制备了一系列的NH2-SBA-15催化剂, 通过微量吸附量热技术定量地分析了该催化剂表面碱性中心的强度、数量和分布状态. 实验结果表明, SBA-15在 550 ℃焙烧6 h, 氨基硅源与SBA-15质量比为1.5, 是合成NH2-SBA-15催化剂最适宜的条件. 运用微量吸附量热技术实现了对NH2-SBA-15催化剂合成条件的优化.

| Abstract: | A series of NH2-SBA-15 were prepared via a aminopropyl-triethoxysilane to react with SBA-15 and characterized with N2-BET,XRD,elementary analysis and FTIR and flavanone was synthesize via condensation between 2'-hydroxyphenyl methyl ketone and benzaldehyde catalyzed by the catalyst NH2-SBA-15.The microcalorimetric technique was used to study quantitatively the surface base sites of NH2-SBA-15 with intensity,number and distribution.It was shown that the reaction condition(550,6,1.5) was the most compatible for synthesis of NH2-SBA-15. |
