摘要：

脂肪伯醇催化转化制备相应的醛是具有挑战性的课题, 目前多采用负载的单金属铜基催化剂. 本文报道了双金属催化剂Cu-Ni/γ-Al2O3催化3,3-二甲基-1-丁醇脱氢制备相应的醛, 在相同反应条件下, Cu-Ni/γ-Al2O3比单金属催化剂Cu/γ-Al2O表现出更高的催化活性, 能将一系列脂肪伯醇高选择性转化为相应的醛.

关键词: 脂肪伯醇, 醛, 铜-镍, 催化, 脱氢

Abstract:

The catalytic conversion of non-activated primary aliphatic alcohols to aldehydes is a challenge, and monometallic Cu-based catalysts loaded on different supports have often been used for these reactions. Cu-Ni/γ-Al2O3 bimetallic catalysts were prepared and used for anaerobic dehydrogenation of 3,3-dimethyl-1-butanol to 3,3-dimethyl-1-butanal. These catalysts exhibited higher activity than Cu/γ-Al2O3 under the same reaction conditions, and a wide range of primary aliphatic alcohols were efficiently converted to the corresponding aldehydes over Cu-Ni/γ-Al2O3 under mild conditions.
