摘要:
Process for hydrogenating unsaturated compounds in the liquid phase in the presence of a soluble catalyst obtained by reacting an organometal derivative or a metal hydride with a synergistic mixture of (a) a compound of zinc, zirconium, manganese, molybdenum, or iron and (b) a nickel or cobalt compound.
摘要:
Diphenol propane is hydrogenated in the presence of a homogeneous catalyst; water and an alcohol are added at the end of the reaction to assist in the separation of the catalyst residues.
摘要:
Ketones are converted by hydrogenation to the corresponding secondary alcohols, in the presence of a soluble catalyst which is obtained by contacting a metal compound, for example a cobalt, nickel or iron salt, with a reducing agent, preferably a trialkylaluminum compound, the reaction being carried out with added metal alcoholate, preferably an alkali metal alcoholate.
摘要:
Unsaturated compounds are hydrogenated in the presence of a catalyst obtained by reacting an organoaluminum compound with a transition metal carboxylate and an organic carboxylic acid.
摘要:
Process for manufacturing dicyclohexanol propane by hydrogenating, with molecular hydrogen, in the presence of a hydrogenation catalyst, diphenol propane dissolved in 2 ethyl-hexanol, adding water at the end of the reaction, distilling the reaction product and separating from the distillate an aqueous phase and a 2 ethyl-hexanol phase, the latter being reused as solvent for the reaction.
