Procedure

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.
