协同的酸性位点(B和AMI)。1对β蒎烯二聚反应的催化活性优于 B-VCM-41和 A -MCM41。1用量为2%时
聚产物的产率高达62.82%。循环使用4次,1的催化性能基本不变

Abstract The diatomic modified mesoporous material B-AL-MCM-41 catalyst(1 was prepared by the
hydrothermal method The structure was characterized by TEM, FTHR, XRD), N2-asorption analysis
and NH PD. The catalytic property of 1 on the dimerization of B-pinenewas investigated as well. The
resulls showed that 1 has highly ordered mesoporous structure and Iwo cooperative acid sites (13 and
Al).1 exhibited higher catalytic property than B-MCM-41 and AL-MCM-41. The yield of -pinene
dimerization product could reach up to 62. 82%c under a low catalyst dosage of 2%0. The catalytic prop
erty of 1 remain stable after recycling for four times
