Procedure
The material contained in the base in Example 1 was used in this experiment. Acetic anhydride containing 1 weight percent benzenesulfonic acid was fed at 20.76 mL per hour while maintaining the acetaldehyde feed at 12 mL per hour. These feed rates gave an acetaldehyde:acetic anhydride feed ratio of 1:1. After operating 5.1 hours to adjust conditions, an additional 26.7 hours of operation produced an average of 11.5 g per hour vinyl acetate, 1.75 g per hour acetaldehyde, and 5.72 g per hour acetic acid in the overhead takeoff, which was operated to remove the distillation fraction boiling below or at 89° C.
