Abstract
The present invention relates to process and apparatus for removing aldehydes from acetone. More specifically, the present invention relates to a process and apparatus for removing aldehydes from acetone by reacting the aldehydes with caustic in an acetone column and washing the organic phase with a plurality of water streams.
Claims20
A process for removing aldehydes from acetone, comprising:
- introducing a feed stream containing at least one organic compound in a column;
- introducing an aqueous caustic scrubbing solution into the column;
- introducing a first water stream into a lower portion of the column;
- introducing a second water stream into the lower portion of the column;
- removing spent aqueous caustic and aldehyde solution from the column;
- and
- removing an organic product from an upper portion of the column having a reduced level of aldehydes relative to the feed stream.
