Improvement of the selectivity of isophorone hydrogenation by Lewis acids [PDF]

Royal Society Open Science, 2018
The selective hydrogenation of isophorone (3,5,5-trimethyl-2- cyclohexen-1-one) to produce 3,3,5-trimethylcyclohexanone (TMCH), an important organic solvent and pharmaceutical intermediate, is of significance in industry.

Comparative Study of Pd–Ni Bimetallic Catalysts Supported on UiO-66 and UiO-66-NH₂ in Selective 1,3-Butadiene Hydrogenation

Nanomaterials, 2022
Selective hydrogenation of 1,3-butadiene (BD) is regarded as the most promising route for removing BD from butene streams. Bimetallic Pd–Ni catalysts with changed Pd/Ni molar ratios and monometallic Pd catalysts were synthesized using two differently ...
