Selective hydrogenation of dimethyl terephthalate over a potassium-modified Ni/SiO2 catalyst

Selective hydrogenation of DMT to DMCD was achieved a using KF-modified Ni/SiO 2 catalyst. Doping only 0.5 wt% of KF by post-impregnation significantly improves the reactivity and selectivity (41% vs 95% conversion; 83% vs 96% selectivity).
