Abstract (en)

[origin: DE19748573A1] The invention relates to a method for producing heat-stable epoxy compounds, wherein olefinically unsaturated compounds are epoxidized in a manner known per se and the resulting oxirane compounds (a) are washed with water and/or aqueous alkali solution and (b) the organic value phase is separated and dried. The inventive method is characterized in that said organic value phase is subsequently treated with solid, basic aluminum oxide, aluminum hydroxide and/or alkali silicates and filtered.
