ABSTRACT:
Cyclic compounds, particularly cycloalkanes and cycloalkenes can be oxidized using known metal oxidation catalysts in an organic ester solvent with considerable advantage over prior art solvents. For example cyclohexane was oxidized with a combination cobalt-manganese catalyst at a conversion of 15.3 mole % to give 20.3 mole % selectivity to adipic acid. Although this is not particularly high, 70.9 mole % of the converted cyclohexane was precursors of adipic acid which on recycle to the oxidation at a conversion of 14.4 mole % (total reaction time 0.23 hours) gave 64.6 mole % selectivity to adiptic acid and a total selectivity to adipic acid and precursors of 89.2 mole %.
