SYNTHESIS,CHARACTERIZATION OF MESOPOROUS MOLECULAR SIEVE SULPHATED-Al-MCM-?41 AND ITS CATALYSIS ON TERPINEOL ESTERIFICATION

Abstract：A mesoporous molecular sieve Al-MCM-?41 was synthesized directly by hydrothermal method.In this process,crystallization was controlled at 145?℃ and 24～28?h.Al-MCM-?41 was disposed by different ways to prepare SO2-4-Al-MCM-?41.SO2-4-Al-MCM-?41was characterized by XRD,BET and FT-IR measurements.The results show that the skeleton of mesoporous molecular sieves has not been destroyed and the crystallinity was improved.By FT-IR,it was proved that SO2-4 has been incorporated within the skeleton.SO2-4-Al-MCM-?41 was used as catalysts in the reaction of synthesizing terpinyl acetate.The results showed that SO2-4-Al-MCM-?41 synthesized by using 0.25?mol/L H2SO4 to infuse calcined Al-MCM-?41 had the highest catalytic activity.

摘　要：通过水热合成法合成出中孔分子筛Al-MCM-?41.合成条件:晶化温度145 ℃,晶化时间24～28 h.用不同方法处理Al-MCM-?41得到SO2-4-Al-MCM-?41.通过XRD、BET和FT-IR对SO2-4-Al-MCM-?41进行表征.结果表明:分子筛的骨架没有被破坏,结晶度较好.从FT-IR图上看出SO2-4已进入分子筛骨架内部.将SO2-4-Al-MCM-?41用于催化松油醇酯化反应.气相色谱分析反应结果表明,用0.25 mol/L H2SO4浸泡焙烧过的Al-MCM-?41得到的SO2-4-Al-MCM-?41催化活性最好.
