通过浸渍法合成了负载在介孔分子筛SiO 2 / Al 2 O 3上的三甲氧基甲硅烷基丙胺[(CH 3 O)3 Si(CH 2)3 NH 2 ]负载的一系列胺催化剂。各种芳香醛和1-庚醛的醛醇缩合用于测试胺官能化SiO 2 / Al 2 O 3的酸碱协同作用。溶剂,反应温度,苯甲醛与1-庚醛摩尔比,不同载体(SiO 2,Al 2 O 3和SiO 2 -Al 2 O 3),催化剂用量和催化剂的可回收性进行了研究。负载了5 mmol胺的样品显示最高的苯甲醛转化率(100%)和对茉莉醛的选择性(97%)。

Aldol condensation of furfural with acetone and a series of aldehydes in the presence of PAF-SO3H acid catalyst based on mesoporous aromatic frameworks was studied. The reaction course depending on the process temperature, catalyst amount, and reactant ratio was studied for the furfural condensation with acetone as an example. The catalyst can be reused in several cycles without appreciable activity

of amine catalysts supported on mesoporous molecular sieves SiO2/Al2O3 with trimethoxysilylpropylamine [(CH3O)3Si(CH2)3NH2] loading varying from 3 mmol to 6 mmol were synthesized by impregnation method. The aldol condensation of various aromatic aldehydes and 1‐heptanal was used to test the acid‐base cooperativity of amine‐functionalized SiO2/Al2O3. The effects of solvent, reaction temperature, benzaldehyde
