In the part two, we reported the classical Knoevenagel condensation between aromatic aldehydes and acyclic active methylene compounds or cyclic active methylene compounds containing heteroatom such as (2-thio)barbituric acid, Meldrum's acid using ionic liquids as reaction medium.

在第二部分中我们研究了离子液体中开链活性亚甲基化合物、杂环类活性亚甲基化合物如(2-硫代)巴比妥酸、Meldrum's酸与芳香醛之间的Knoevenagel缩合反应。

When the mesostructure is basically formed, the pH value of the reaction system is adjusted to 7-8 and then the hydrothermal crystallization is prolonged for some time to obtain heteroatom-incorporated mesoporous silica. The aim of adjusting pH value to near neutral is to change heteroatom species from the cationic to oxo form and therefore can enter the mesoframework through condensation with silanol groups in the wall.

该方法主要的特点是：操作简单（以调节体系pH值代替繁琐的后处理过程），效率高（可以得到Si/Al=5且铝物种全部处于四配位的骨架位置的Al-SBA-15），不破坏产物有序结构（产品具有高度有序的介孔结构），具有普遍性（适用于多种杂原子的掺杂如铝、钛、钒）。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.
