Selective hydrogenation of α,β-unsaturated aldehydes has been tried over alumina supported Co(0) catalyst. Various α,β-unsaturated aldehydes were selectively hydrogenated to form unsaturated alcohols over Co catalyst. Especially leaf alcohol, used as a fragrance, was produced by hydrogenation of leaf aldehyde with high selectivity. The reaction was tried in a liquid phase using ethanol as a solvent. However the activity and selectivity depended on the solvent seriously. Comparing some solvents, primary alcohol was found to be the best solvent. Addition effect of second metal on Co was examined and Pt was found to be an effective promoter.

在氧化铝负载Co（0）催化剂上进行了α，β-不饱和醛的选择性加氢反应。在Co催化剂上，α，β-不饱和醛选择性加氢生成不饱和醇。特别是叶醛加氢高选择性地生产了用作香料的叶醇。使用乙醇作为溶剂在液相中尝试该反应。但催化剂的活性和选择性对溶剂的依赖性较大。通过对几种溶剂的比较，确定了伯醇为最佳溶剂。研究了第二金属对Co的添加效应，发现Pt是一种有效的促进剂。
