Abstract
Provided is a method for producing an aldehyde that provides a target aldehyde at a high conversion rate over an extended period of time. It is a method for producing an aldehyde comprising bringing a raw material gas containing a primary alcohol having 4 to 18 carbon atoms and water into contact with a dehydrogenation catalyst containing copper and iron so as to dehydrogenate the alcohol contained in the raw material gas, thereby obtaining an aldehyde, wherein the raw material gas has a water partial pressure of 0.2 kPa to 99 kPa.
