Abstract:
The possibilities of developing catalytic processes for the synthesis of 2-methylanthraquinone from
1,4-naphthaquinone (NQ) and isoprene, and synthesizing 2,3-dimethylanthraquinone from NQ and
2,3-dimethylbutadiene in the presence of aqueous solutions of high-vanadium heteropoly acid (HPA) as a
bifunctional catalyst are examined. Two methods for catalyst regeneration are discussed: oxidation with oxygen
at = 0.3–0.4 MPa and with concentrated nitric acid at atmosphere pressure. It is shown that regeneration
with nitric acid ensures deeper oxidation of the reduced catalyst. Complete restoration of the properties
of the catalyst following regeneration offers the possibility of its repeated use in the processes discussed in
this work
