发明名称 Improved process for preparing acetaldehyde from ethylene and oxygen
摘要 Oxidation of a reaction gas in the presence of a catalyst solution (I) involves (a) reaction to form a reaction mixture containing droplets of (I); (b) removal of (I) droplets in a first separator; and (c) scrubbing to remove the oxidation product. The novelty is that (d) the reaction mixture is passed through a second separator, between the first separator and scrubber, to remove residual (I). Independent claims are also included for: (a) the separator which is a turbulence separator with means of producing turbulent flow, preferably guide vanes; and (b) the use of a turbulence separator for depositing droplets from gas streams in the saturated vapor region.
