摘要

Commercial 5 wt.%Pd-containing catalysts doped with cinchonidine were investigated in the enantioselective hydrogenation of (E)-2-methyl-2-butenoic acid (P = 4.0 MPa of H₂, T = 298 K) with the aim of determining how the activity and enantioselectivity may be affected by specifications of the catalytic system (metal dispersion, support acidity and surface area).
