Additional experience with this synthesis has shown that the method as originally published is not given in sufficient detail to ensure infallible results. These details are supplied in the present paper. It has been found also that potassium acetate is a helpful ingredient in the reaction mixture. With it, the product seems to be more easily purified than otherwise. In addition to Dibenzyl Ketone it has been found that Phenylacetone is also a product of the reaction. These steps account for the changes which occur. Phenylacetone and Dibenzyl Ketone evidently are pyrolytic products of phenylacetic acetic anhydride and phenylacetic anhydride, respectively. That dibenzyl ketone is formed in greater yields than Phenylacetone is evidence that reaction 3 has a greater reaction rate than reaction 2. Or, if reaction 3 is an equilibrium reaction the evidence would indicate that phenylacetic acetic anhydride disappears more rapidly through reactions: Indirectly this may indicate that reaction 4 is faster under the conditions obtained in the experiment, than reaction 2. Fifty grams of phenylacetic acid was weighed into a cc. A thermometer was placed in the liquid and the mixture refluxed for two hours, during which time the thermometer in the liquid reached degrees. A good fractionating column was inserted in place of the reflux condenser and the mixture distilled. The distillation was carried out very slowly so that the distillate was mainly acetic acid. After forty-five minutes carbon dioxide evolved slowly. The rate increased to a maximum at seventy-five minutes, but carbon dioxide was still being evolved slowly when the distillation was stopped. A total of 4 liters of gas was collected which was pure carbon dioxide over Heating the liquid above produced resinification with a decrease in the yield of ketones. The residue was placed in a 50 cc. Acetic anhydride 5 cc. The mixture was distilled at 3 mm. At degrees a 26 gram fraction then residue. Redistillation of the 26 gram fraction gave 8 g. The Phenylacetone was identified as the phenylhydrazone,2 m. Experimental Part Fifty grams of phenylacetic acid was weighed into a cc.
