Abstract
The bisphenol F synthesis from the liquid-phase phenol and formaldehyde condensation reaction in the presence of water over microporous H-beta zeolites, with different Si/Al ratios, has been investigated. The catalysts have been characterized for their phase purity and acidity. With an increase in the aluminum content in beta zeolite, the acidity is increased gradually; however, the catalytic activity is increased and passes through a maximum. Among the different Al-containing beta zeolites (having Si/Al ratios from 11.5 to 124.5 mol molâ1), the catalyst with Si/Al ratio of 75.0 mol molâ1 shows the best catalytic performance in the bisphenol F synthesis process. The influences of catalyst amount, phenol/formaldehyde ratio and reaction temperature on the phenol and formaldehyde condensation over the catalyst showing the highest bisphenol F activity have been thoroughly studied.
