The palladium catalyst. PALLADIUM went GOLD binary heterogeneous metal HETEROGENEOUS BIMETALLIC VINYL ACETATE for production of vinyl acetate

摘要

Wantqayyt, long-term production of vinyl acetate vinyl acetate.19 summary: the invention provides a catalyst of palladium metal heterogeneous. The duo went heterogeneous bimetallic palladium-gold catalyst to produce vinyl acetate vinyl acetate of PE ethylene, Astyk acid acetic acid WaksjynOxygen. The present invention of the first catalyst to form the coating casing palladium colloidal dispersion of palladium on the surface of the catalyst, and is placed above the second strengthening material of metallic gold gold metal colloidal catalyst on the surface of the material strengthened.Use the gold compound, organic Mlny organometallic gold to scatter the gold gold catalyst on the surface of the material strengthened.Does not require gold metallic organic compound organometallic gold to install, which commonly cause in a retained metallic gold gold metal is low.The palladium catalyst. He went palladium-gold chip of the invention has a retained metallic gold gold metal high, and shows the continuity
