证明一种新的二金属铼-锡催化剂在温和氢化条件下能够还原油酸为9-十八烯-1-醇(顺式和反式异构物)具有显著的收率。该论文报导的研究涉及催化剂制造方法,载体的类型,催化剂原料,金属的克分子比,活化和在活性上反应条件诸方面的效果以及催化剂的选择性。在氧化铝上由过铼酸铵和四氯化锡化合衍生的催化剂性能最好,在氢化过程中锡的存在对于油酸烯键保护催化剂是必不可少的。 It is demonstrated that a novel two-metal rhenium-tin catalyst capable of reducing oleic acid under mild hydrogenation conditions has significant yield of 9-octadecen-1-ol (cis and trans isomers). The studies reported in this paper relate to catalyst making methods, the type of support, the catalyst feedstock, the molar ratio of metal, the effect of activation and reactive conditions on the activity, and the selectivity of the catalyst. The catalyst derived from the combination of ammonium perrhenate and tin tetrachloride on alumina is the best, and the presence of tin during the hydrogenation is essential for oleic acid olefinic protection catalysts.
