Abstract: A process for greatly improving the color index of polyhydric alcohols, especially trimethylolpropane, by hydrogenation comprises using, in the hydrogenation, an alcohol which has already been purified by distillation. The catalysts used are those conventionally employed in hydrogenations, preferably copper, nickel, palladium or ruthenium catalysts.

Abstract: A process for the hydrogenation of a monocyclic or polycyclic aromatic which may be unsubstituted or substituted by at least one aikyi group comprises bringing the aromatic into contact with a hydrogen-containing gas in the presence of a catalyst comprising at least one metal of transition group VIII of the Periodic Table as active metal applied to a structured or monolithic support.

Abstract: The invention relates to Raney alloy catalysts, which are applied to a support and which have an extremely thin layer comprised of the Raney alloy with a thickness ranging from 0.01 to 100 mu m. These catalysts are produced by vacuum metallizing the respective metals. The catalysts are generally suited for all known hydrogenation and dehydrogenation reactions and are extremely resistant to abrasion.
