Reactions of phenol and methanol catalyzed by MgO have been explored by kinetic measurements and in situ IR spectroscopy combined with computational studies of sorbed molecules. On MgO, methanol partly transforms to formaldehyde above 250°C. Adsorbed phenol forms phenolate species, and the energetically preferred mode of adsorption leads to an almost orthogonal orientation of the aromatic ring with...
Acid-treated montmorillonites belonging to the K series (supplied by Süd-Chemie) were tested as heterogeneous catalysts for the liquid-phase acylation of 1,3-dihydroxybenzene with benzoic acid; this reaction may represent an environmentally friendly alternative to the use of benzyltrichloride as the acylating agent. It was found that conversion was proportional to the Al content in samples; the catalytic...
