Efficient catalytic hydrogenation of acrylic rosin over high-activity Pd/C catalyst under mild conditions

In the present work, efficient catalytic hydrogenation of acrylic rosin (AR) were extensively investigated. Qualitative and quantitative analysis of AR and hydrogenated acrylic rosin (HAR) were carried out by GC and GC–MS, and the reaction pathway network about catalytic hydrogenation of AR was constructed. In addition, a Pd/C catalyst with well-dispersed ultrafine nano-palladium was prepared by impregnation method using Pd(NO3)2·2H2O precursor and put into use for the catalytic hydrogenation of AR. The structural properties of the catalyst were measured via XRD, TEM, ICP-OES, XPS, and BET. The characterizations showed that the ultrafine Pd nanoparticles (NPs) with an average Pd NPs size of 2.29 nm and consisting of 3.1
