Abstract
The hydrogenation of unsaturated aldehydes was studied over ultrasonically pretreated silica supported platinum catalyst. In the hydrogenation of cinnamaldehyde a remarkable reaction rate and cinnamyl alcohol selectivity increase was observed. Using other unsaturated aldehydes the reaction rate and unsaturated alcohol selectivity increased moderately.
摘要
在超声预处理的二氧化硅负载铂催化剂上研究了不饱和醛的氢化反应。在肉桂醛的氢化反应中，观察到反应速率和肉桂醇选择性显著提高。使用其他不饱和醛时，反应速率和不饱和醇选择性适度增加。
