It was established that the adducts of the diene synthesis of 1,4-benzo- and 1,4-naphthoquinones with butadiene get oxidized by Mo-V-phosphorus h heteropolyacids heteropoly acids (HPA) and their salts in a two-phase system to form 1,4-naphtho- and 9,10-anthraquinones. The promising character of the multistage catalytic synthesis of 1,4-quinones in the presence of HPA within a single technological operation was demonstrated.
