摘要： A method of hydrogenating unsaturated compound with multi-carboxylic acid groups is provided, which includes introducing hydrogen to an unsaturated compound with multi-carboxylic acid groups in the presence of a catalyst to hydrogenate the alkene or alkyne group of the unsaturated compound with multi-carboxylic acid groups without hydrogenating the carboxylic acid groups of the unsaturated compound with multi-carboxylic acid groups. The catalyst includes a support, and palladium and metal oxide loaded on the support.
