Recent progresses in selective catalytic hydrogenation of cinnamaldehyde to cinnamyl alcohol

综述了近年来肉桂醛选择性加氢合成肉桂醇催化剂及其反应机理的研究进展。对贵金属(铂、钌、金)和非贵金属(钴、铜)非均相催化剂的结构和性能进行了分析。指出选择合适的活性组分、载体、助剂以及活性组分粒径是获得高活性和高选择性催化剂的关键,改性的非贵金属加氢催化剂价廉易得,应用前景广阔。

The recent progresses of the catalysts and the mechanism in selective catalytic hydrogenation of cinnamaldehyde to cinnamyl alcohol are reviewed. The structures and characteristic properties of precious metal （platinum, ruthenium, gold） and non-precious metal （cobalt, copper） catalysts are summarized. It is pointed out that active component, support, promoter and the metal particle sizes are the key to obtain the catalysts with high activity and selectivity for cinnamaldehyde hydrogenation. Modificated non-precious metal catalysts, which are inexpensive and readily available, are potential in selective hydrogenation of cinnamaldehyde to cinnamyl alcohol for industrial application.
