Abstract
A process is provided for improving the color number of polyhydric alcohols, especially trimethylolpropane, by catalytic hydrogenation, the polyhydric alcohol used in the hydrogenation having been purified by distillation following its preparation, wherein the hydrogenation is carried out in the presence of a macroporous supported heterogeneous catalyst containing, as the active metal, at least one metal of subgroups VII to X of the Periodic Table.
