摘要

Provided is a method for producing n-propyl acetate, which is capable of obtaining high-purity allyl acetate with a low amount of coexisting water and is capable of producing n-propyl acetate with a high yield. The method includes an extraction process of subjecting a raw material liquid containing allyl acetate and water to an extraction operation using water as an extraction solvent and separating the extract into an oily phase and an aqueous phase, a distillation process of distilling the oily phase to obtain a distillate containing allyl acetate as a main component, and a hydrogenation process of subjecting the distillate to a hydrogenation reaction.
