在小型高压反应釜中研究了铑系催化剂对于α，ω－ 二元羧酸单酯加氢生成ω－ 羟基羧酸酯的催化性能。结果表明，Ｒｈ － Ｒｅ 以及Ｒｈ － Ｍｏ 双组份催化剂具有良好的催化加氢性能；α，ω－ 十五烷二酸单甲酯在Ｒｈ － Ｒｅ 和Ｒｈ － Ｍｏ双组份催化剂上加氢生成ω－ 羟基十五烷酸甲酯的收率分别达到８７－５ ％ 和８４－７ ％ ；其它α，ω－ 二元羧酸单酯在Ｒｈ －Ｍｏ 双组份催化剂上加氢生成相应的ω－ 羟基羧酸酯的收率也达到８０－９ ％ ～９１－３ ％ 。反应温度对α，ω－ 二元羧酸单酯加氢生成ω－ 羟基羧酸酯的收率有较大的影响，乙二醇二甲醚作为溶剂有利于目的产物的生成。
The catalytic performance of rhodium-based catalysts for the hydrogenation of α, ω-dicarboxylic acid monoesters to ω-hydroxycarboxylic esters was investigated in a small autoclave. The results show that the Rh - Re and Rh - Mo two - component catalysts have good catalytic hydrogenation performance. The α, ω - pentadecanedioic acid monomethyl ester is hydrogenated on the Rh - Re and Rh - Mo two - component catalysts The yields of methyl ω-hydroxy pentadecanoate reached 87-5% and 84-7%, respectively. Other α, ω-dicarboxylic acid monoesters were hydrogenated over the Rh-Mo bicomponent catalyst to produce the corresponding ω - hydroxy carboxylic acid ester yield also reached 80-9% ~ 91-3%. The reaction temperature has a great influence on the yield of ω-hydroxycarboxylate by hydrogenation of α, ω-dicarboxylic acid monoesters. The use of ethylene glycol dimethyl ether as a solvent favors the formation of the desired product.
