摘要

Herein, the catalytic performance of nickel nanoparticles (particle size ~ 3 nm), supported on polymeric resin (Ni-TS-NH2), was investigated in the three-phase selective hydrogenation of 2-methylbut-3-yn-2-ol (MBY) to 2-methylbut-3-en-2-ol (MBE)—precursor in the synthesis of vitamins A and E. The goal of this work was to achieve high selectivity toward the desired product while maintaining high substrate conversion at reaction conditions requiring the lowest possible energy input. Investigations into the effects of reaction temperature, hydrogen concentration, and contact time led to the establishment of the optimal reaction conditions. ~ 100% selectivity to 2-methylbut-3-en-2-ol with 50% MBY conversion was obtained at 10 °C, 1 bar, 0.5 mL/min reactant flow rate, and 15 mL/min H2 flow.
