Acid-catalytic 1,3-butadiene condensation with para-quinones followed by the obtained product oxidation may be performed in one stage as one-pot process, if assisted by the aqueous solutions of Mo-V-P heteropoly acids with a composition of HaPzMoyVxOb. 1,4-naphthoquinone (NQ) condensation with 1,3-butadiene in HPA solutions (brutto-composition H15P4Mo18V7O89 and H17P3Mo16V10O89) in the presence of hydrophylic organic solvents (acetone, 1,4-dioxane) provides 70% yield of 9,10-anthraquinone (AQ) containing no less than 90% AQ. In the same conditions reaction NQ with substituted 1,3-butadienes in the presence of the aqueous H17P3Mo16V10O89 (HPA-10) solution allows to prepare substituted AQ with yield up to 90% and purity up to 99%. The catalysts are regenerated by oxygen in separate stage and are reused.
