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.

Description

[0001] priority statement [0002] This application claims the benefit of US Provisional Application Serial No. 62 / 526901, entitled "Method and Apparatus for Removing Aldehydes from Acetone," filed June 29, 2017, which is incorporated herein in its entirety. technical field [0003] The present invention relates to a method and apparatus for removing aldehydes from acetone. More specifically, the present invention relates to a method and apparatus for removing aldehydes from acetone by reacting the aldehydes with caustic in an acetone column and washing the organic phase with multiple streams of water. Background technique [0004] A method for the removal of aldehydes from acetone is described. Aldehydes are acetone product impurities from the phenol process that produces both acetone and phenol from cumene. Aldehydes are formed from ethylbenzene, alpha-methylstyrene (AMS) and n-propylbenzene in the cumene feed. Aldehydes are typically removed via reactive distillation b...
