Suggested is a new process for the selective hydrogenation of (poly)unsaturated hydrocarbons, in particular polyunsaturated fatty acid alkyl esters into the respective saturated and/or monounsaturated species, of aldehydes into respective alcohols and of aromatic compounds into respective saturated cyclic compounds using homogenous catalysts in a biphasic aqueous/organic solvent system, which is characterised in that said catalysts represent complexes of main-group I-V metals with water-soluble amine ligands.
建议采用一种新工艺,在双相水溶液/有机溶剂体系中使用均质催化剂,将(多)不饱和碳氢化合物,特别是多不饱和脂肪酸烷基酯选择性氢化为相应的饱和和/或单不饱和种类,将醛类氢化为相应的醇类,以及将芳香族化合物氢化为相应的饱和环状化合物。
