摘要
以对甲苯磺酸铜和介孔分子筛MCM-41为原料,通过浸渍法在碱性条件下将对甲基苯磺酸铜[Cu(TBS)_(2)]负载到用水热法合成的介孔分子筛MCM-41上,通过IR、TG、X射线粉末衍射技术对其进行表征,以Biginelli反应为探针研究其催化性能。结果表明,当反应原料n(苯甲醛)∶n(乙酰乙酸乙酯)∶n(N-甲基脲)=1∶1∶1.2时,催化剂Cu(TBS)_(2)/MCM-41(0.4 mmol)的催化效果较好,反应时间13 min,产率达到87.3%。
Copper p-methylbenzenesulfonate was supported onto hydrothermally-synthesized mesoporous MCM-41 molecular sieve by impregnation method under alkaline condition and was characterized by IR,TG,and powder X-ray diffraction(PXRD).Its catalytic performance was studied using Biginelli reaction as the probe reaction.The results showed that Cu(TBS)_(2)/MCM-41(0.4 mmol)exhibited better catalytic performance,with product yield of 87.3%under condition as follows:ratio of n(benzaldehyde)∶n(ethylacetoacetate)∶n(N-methylurea)of 1∶1∶1.2 and reaction for 13 min.
