Abstract

The oxidation of ethylene to acetaldehyde with a supported liquid-phase (SLP) Wacker catalyst has been investigated. The active phase of the catalyst, a chlorinated solution of PdCl2, CuCl2, and Cu(NO3)2, was supported on three aluminas of differing texture. The reaction was studied in the temperature range 40-80 ¯C as a function of the catalyst liquid loading. A unimodal size distribution was found desirable in optimizing overall activity, and maximum activity was obtained for a liquid loading of about 0.1 volume liquid catalyst phase/volume pores. Kinetic studies in excess oxygen suggest that the reaction is approximately first order in ethylene. Catalyst deactivation is probably related to a loss of Cl- during the reaction cycle.
