Composition useful for the catalytic hydrogenation of alkynes method for preparing the Catalyst and Process for the selective hydrogenation of an alkyne

摘要

The present Invention relates to a catalytic composition comprising Palladium, at least a Chemically Bonded (preferably alkali metal Potassium)Fluoride and Chemically Bonded inorganic support material (preferiblementeal u00famina), where the Atomic ratio of flu00faorcon on Alkali Metals is from 1.3: 1 to 4: 1.Preferably, The Silver is also present in The Catalyst composition.The catalizadordescrito previously is used as a talizador ca in the selective hydrogenation of alkynes with C2 C10 (preferably acetylene) in the presence of the alquenoscorrespondientesSULFUR impurities.The Catalyst composition is prepared by contacting unacomposiciu00f3n solid for palladium and the support material with an inorganic metal Compound dissolved Alkali and Fluorine.
