Hydroxylation of aromatic ring in corroding metal systems

In order to find a new efficient catalyst for the aromatic hydroxylation reaction, dissolution of several metals (Cu, Fe, Cr, Pb and Sn) into aqueous acid solutions containing benzoic acid was studied. In all systems, three isomers of monohydroxybenzoic acid and some dihydroxy compounds were detecte...

Description
Summary:In order to find a new efficient catalyst for the aromatic hydroxylation reaction, dissolution of several metals (Cu, Fe, Cr, Pb and Sn) into aqueous acid solutions containing benzoic acid was studied. In all systems, three isomers of monohydroxybenzoic acid and some dihydroxy compounds were detected upon metal dissolution. Above all, the system of Sn in sulfuric acid is particularly promising as a candidate for a new catalyst system.
