| titleOfInvention | Method of producing acetone with low aldehydes content |
| abstract | Methods and systems for preparing acetone from cumene hydroperoxide (CHP) are disclosed. The methods and systems involve an acetone purification column configured to separate acetone from other components of the product/reactant stream. The acetone purification column is equipped with a side draw configured to route a portion of the column contents to a caustic treating vessel where the contents are reacted with a dilute aqueous alkaline solution to remove aldehydes from the acetone product. The contents of the caustic treating vessel are then routed back to the acetone purification column. Using a separate caustic treating vessel for the aldehydes removal provides increased contact time between the acetone product and the alkaline solution, thereby affording greater aldehydes removal. |
