Abstract
One object of the present invention is to provide a method for producing n-propyl acetate by the hydrogenation reaction with a hydrogenation catalyst, using an allyl acetate containing solution as a raw material, wherein the method can prevent the conversion rate of the substrate (allyl acetate) from decreasing with time and the product quality from deteriorating, and the present invention provides a method for producing n-propyl acetate including a first hydrogenation step in which a raw material solution containing allyl acetate and a hydrogen containing gas are reacted under a pressure P1 of 1.0 MPa G (gage pressure) or more in the presence of a hydrogenation catalyst, to hydrogenate the allyl acetate to produce a hydrogenation reaction product containing n-propyl acetate: a gas-liquid separation step in which the hydrogenation reaction product is gas-liquid separated into to produce a crude n-propyl acetate solution containing n-propyl acetate: and a second hydrogenation step in which non-reacted allyl acetate contained in the crude n-propyl acetate solution is hydrogenated using hydrogen dissolved in the crude n-propyl acetate solution in the presence of a hydrogenation catalyst.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
