Abstract:
Kinetic peculiarities of regeneration of the aqueous solutions of non-Keggin-type Mo-V-P heteropoly acids HaPzMoyVx′Ob (HPA-x′) and their acidic salts by O2 are studied. The HPA-x′ solutions have heightened thermal stability that permits to consider them as highly efficient catalysts for different oxidation processes. In the HPA-x′ and their salts solutions, these peculiarities prove to be similar. The studied reaction is of the first order with respect to O2 and V(IV), if [V(IV)] is higher than 0.8 M. As [V(IV)] decreases during the reaction, its order with respect to V(IV) increases to the third. The apparent activation energy of the reaction at temperatures 150–170°С is 37.5 kJ mol−1. The obtained kinetic equation was used to calculate a new effective air reactor for the regeneration of the homogeneous HPA-x′ catalyst in a pilot process of methylethylketone synthesis.
