In oxidative processes involving homogeneous catalysts based on aqueous solutions of Mo-V-phosphoric heteropoly acids with Keggin composition H3+xPMo12-xVxO40 (НРА-х), the catalyst regeneration step (oxidation of the reduced НРА-х form) usually is the key reaction. It determines the processability of the catalyst, i.e. the possibility to implement an effective two-stage catalytic process of substrate oxidation with oxygen. The work discusses various ways of regeneration of the НРА-х solutions: 1) by O2 at temperatures 150−170 С and РО2 = 3−4 atm; 2) by the 30 % H2O2 solution and 3) by oxygen air under atmospheric pressure with the addition of nitric acid
