METHOD FOR PRODUCING 2,3-PENTANEDIONE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing 2,3-pentanedione by a simple method in a high yield. SOLUTION: This method for producing 2,3-pentanedione comprises a stage for reacting hydroxyacetone with paraldehyde in the presence of both an aqueous phase containing an strong organic acid or inorganic acid having a pKa value of <=4 and a phase transfer catalyst.
