The procedure was repeated with separate samples of the above solution to which ethyl-2-cyclohexanone carboxylate, 2-acetyl cyclohexanone, 2-acetyl cyclopentanone, methyl-2-cycloheptanone carboxylate, ethyl-2-oxocyclopentane carboxylate, dibenzoyl methane, and ethyl-4-methyl-2-cyclohexanone-1-carboxylate had been added. The results are shown in Table II. Results obtained with ethyl acetoacetate, which is disclosed in the prior art, are included for comparison.
