A process produces an aromatic compound by bringing an aromatic compound (B) into contact with molecular oxygen (C) in the presence of a catalyst (A) comprising at least one of (A1) a heteropolyacid and/or a salt thereof, and (A2) a mixture of oxoacids and/or salts thereof containing, as a whole, one of P and Si and at least one selected from V, Mo and W to thereby yield another aromatic compound (G) than the aromatic compound (B). The process can produce, for example, a corresponding aromatic hydroxy compound (G1) by allowing the aromatic compound (B) to react with the molecular oxygen (C) further in the presence of a reducing agent (D).
一种过程通过将芳香化合物(B)与分子氧(C)在催化剂(A)的存在下接触,所述催化剂(A)包括至少一种(A1)杂多酸和/或其盐,以及(A2)包含P和Si中的一个和V、Mo和W中至少一个的氧酸和/或其盐的混合物,从而产生另一种与芳香化合物(B)不同的芳香化合物(G)。该过程可以通过在还原剂(D)存在下让芳香化合物(B)与分子氧(C)进一步反应来生产相应的芳香羟基化合物(G1),例如。
