对含有多个可被还原的官能团化合物的催化氢化,难以找到既有高活性又具有高度选择性的催化剂。柠檬醛分子中含有两个碳碳双键和一个醛基,随氢化条件的不同可能生成下列4种产物:
For the catalytic hydrogenation of compounds containing a plurality of functional groups which can be reduced, it is difficult to find both highly active and highly selective catalysts. Citral molecules contain two carbon-carbon double bonds and an aldehyde group, with the hydrogenation conditions may produce the following four kinds of products:
