ABSTRACT:
The present invention includes a process for removing aldehydes from acetone having aldehyde impurities comprising contacting the acetone with a sufficient amount of at least one diamine compound to react with at least a portion of the aldehyde and heating the acetone in the presence of the diamine compound sufficiently to result in reaction of the diamine compound and aldehyde, thus reducing the amount of aldehyde in the acetone. It is preferred that the process is an improvement in a process for purifying crude acetone having aldehydes therein, by fractionally distilling the acetone in a multiple plate distillation, the improvement comprising adding to the acetone a sufficient amount of at least one diamine compound to react with at least a portion of the aldehydes.
