In such a method for producing n-propyl acetate, the concentration of a formyl group-containing compound (such as acrolein, propionaldehyde or 2-methylcrotonaldehyde) and the concentration of an acryloyloxy group-containing compound (such as acrylic acid or allyl acrylate) in the raw material liquid are respectively set to 100 ppm by mass or less. As a result, the deterioration of the hydrogenation catalyst can be suppressed to such an extent that the catalyst can be industrially used.
