Catalytic properties of two series of Keggin-type heteropolycompounds, H_3–2xMn_xPMo₁₂O₄₀ and (NH₄)_3–2xMn_xPMo₁₂O₄₀ (x = 0.25-1.5), have been studied in the process of oxidation of cyclohexanone and/or cyclohexanol to adipic acid, using 30% hydrogen peroxide, in the absence of organic solvent. The main products and by-products have been identified by means of GC-MS analysis. The highest yields of adipic acid are found in the case of H_1.5Mn_0.75PMo₁₂O₄₀ and (NH₄)₂Mn_0.5PMo₁₂O₄₀ compounds.
