    • The invention relates to a method for producing a stabilised catalyst system. According to said method, a salt of a metal from the first, second or eighth subgroup is reduced to colloidal metal in an essentially water-free, oxidation resistant, organic solvent; with a reduction agent and in the presence of a stabiliser, said salt being soluble in said solvent. Alternatively, the metal salt can be hydrolysed to colloidal metal oxide with water, in the presence of a stabiliser. The solvent is selected from aliphatic, aromatic, nitrated aliphatic and nitrated aromatic, halogenated aliphatic and halogenated aromatic hydrocarbons and a hydrophobic stabiliser that is soluble therein is used as the stabiliser. By selecting the solvent in this way, it is possible to avoid unwanted secondary reactions such as the formation of secondary products such as glycols and glycol monoalkylethers to a large extent. The inventive catalyst system or the catalyst that can be isolated from the same can be used for the epoxidation of alkenes in solution. In a particularly preferred embodiment of the invention, a catalyst system containing colloidal silver is used for the epoxidation of ethylene.

    • Disclosed are improved processes for the recovery of 3,4-epoxy-1-butene (epoxybutene) from an epoxidation effluent comprising epoxybutane, butadiene, oxygen and an inert diluent obtained by the selective epoxidation of butadiene with an oxygen-containing gas in the presence of a catalyst and an inert gas. Epoxybutene is separated from the effluent by means of an absorption process using an extractant comprising liquid butadiene and, optionally, a hydrocarbon diluent. The formation of butenediols, by the reaction of epoxybutene and water, in the recovery process is inhibited by the addition of a base, preferably an alkali metal base, to the recovery system.
