Procedure

Next, 67.1 [g] of 2-acetyl-1,4-di-n-butoxybenzene was added to 54 [ml] of ethyl acetate, 83 [ml] of 40 [wt %] peracetic acid was dripped in at 40° C., and the reaction was carried out while stirring at 40° C. for 18 hours. The reaction liquor was poured into 700 [ml] of water at room temperature, and extracted twice with 300 [ml] of ethyl acetate. The extraction solvent (i.e. the ethyl acetate solution) was washed with water, and concentrated by evaporating off the ethyl acetate solvent under reduced pressure. Concentration of the extraction solution was continued until there was almost no further evaporation of ethyl acetate (i.e., almost no further ethyl acetate remained in the extraction solution). Subsequently, the separated crystals were filtered off using filter paper, washed with a small amount of ethyl acetate, and dried to obtain 53.0 [g] of 2-acetoxy-1,4-di-n-butoxybenzene.
