How to separate propanone from propanal

Thread Content

I would like to ask everyone: What method can be used to separate a mixture of propanone and propanal? The propylene content is about 80%, while propionaldehyde accounts for 20%. Propanal and propionone both belong to the class of carbonyl compounds, with 3 carbon atoms each; their boiling points are 56 and 48 degrees respectively, and their properties are very similar. If distillation is used, more than 50 trays are required, the reflux ratio must be greater than 20, and reduced pressure is necessary to carry out the process; as a result, the energy consumption is very high. I would like to ask for a method with lower energy consumption that is suitable for large-scale industrial separation (on a scale of 10,000 tons per year).
