Procedure: Example 1 was repeated except that no water was present in the feed mixture fed to the reactor; the feed rate was 279 ml/hr, the reaction time was 5.5 hours. Analysis of the condensed organic layer by gas chromatography indicated that 5.04 pounds of isobutyrophenone were produced per 100 pounds of propiophenone.

Procedure: In Example 1, using the reactor described above, together with ancillary equipment, a mixture containing 2 moles of propionic acid per mole of benzoic acid was fed to the reactor together with 4 moles of water per mole of benzoic acid at a rate of 249 ml/hr. for 4.5 hours. The reaction temperature was maintained between 445° C. and 450° C. Analysis of the condensed organic layer by gas chromatography indicated that 4.68 pounds of isobutyrophenone were produced per 100 pounds of propiophenone. These data are delineated in Table I. The instrument used was a Bendix Model 2300 dual column programmed temperature gas chromatograph having a thermal conductivity detector. The bridge current was 200 ma. with a 0-1 mv. recorder. The column consisted of two, 10 feet by 1/8 inch stainless steel tubing packed with silicone on an inert support. The column temperature was 190° C. The carrier gas was helium at 30 cc/minute. The reaction temperature was maintained between 445° C. and 450° C
