首次在含钛硅酸盐的非均相催化体系中发现了典型的火山形曲线。提出了一种新的含双氢键的活性中间体。系统的研究结果清楚地证明了氢键受体的高电负性原子与Ti-O-alpha-O-beta-H-end的H端原子之间形成了另一个氢键。
A typical volcano-shaped curve has been found in heterogeneous catalytic systems containing titanosilicates for the first time. A new reactive intermediate with double H-bonds is proposed. Systematic results clearly evidence another H-bond formed between the high-electronegativity atom of the H-bond acceptor and the H-end atom of Ti-O-alpha-O-beta-H-end.
