Abstract
The influence of different process parameters on the hydroxylation of phenol with H2O2 over the titanium silicate molecular sieve TS-2 has been investigated. Apart from the primary products vis., p- and o-dihydroxybenzenes, the corresponding quinones are also formed. Higher Ti contents in the catalyst (TS-2) and higher catalyst concentrations lower the formation of the secondary oxidation products. Solvents have an influence on the relative amounts of the two dihydroxybenzenes in the product. H2O2 efficiency of up to 74% is obtainable at ~28% phenol conversion to dihydroxybenzenes.
