Zusammenfassung:PROBLEM TO BE SOLVED: To synthesize a high-purity monochlorinated compound of 2-acetyl-γ-butyrolactone with high selectivity for an economical purpose. SOLUTION: An alkali metal or alkaline earth metal salt of the 2-acetyl-γ-butyrolactone is used as a starting material for producing the 2-acetyl-2-chloro-γ-butyrolactone, wherein the starting material is reacted with gaseous or liquid chlorine in water, or in a mixture of water and a protonic solvent or a non-protonic solvent.
