The haloalkynes were hydrolyzed to α-haloketones by sulfuric acid promotion in ionic liquids(ILs) with 85%~94% yields. The ILs-H_2SO_4 reaction system could be easily recycled(more five times) without any effect for reaction yield. At the same time, a wide scope of substrates haloalkynes were proper in this reaction system and a series of α-chloro/bromo/iodo acetophenones with different substituent(such as methyl, methoxyl, hydroxyl, nitro etc.) and aliphatic α-haloketones have been obtained in good yields.
