In certain embodiments, the conversion of the acetic acid and propionic acid in mixed acid feed 12 to the product mixture 18 can be accomplished continuously in the gas phase, using a fixed bed reactor or flow bed reactor. The reaction temperature may be in a range from about 200 to about 700 degrees Celsius, preferably, in a range from about 300 to about 500 degrees Celsius, and the WHSV can be in a range from about 0.01 hr to about 10 hr−1, preferably from about 0.05 hr−1 to about 2 hr−1. Acetic/propionic acid/water solutions with steam to carbon ratios from 0 to 20, preferably from 2 to 5 can be used to provide the acetic and propionic acids to the catalyst.
