    Abstract: A process for producing a condensed resin dispersion, which comprises subjecting an aldehyde and a compound condensable with the aldehyde, or their precondensate, to a condensation reaction in a dispersion medium consisting essentially of water and/or an organic solvent, to precipitate fine condensed resin particles which hardly settle in said dispersion medium, and then replacing the water and/or the organic solvent by an active hydrogen-containing compound having at least two active hydrogen-containing groups reactive with isocyanate groups.

    Abstract: A phenyl ester is produced by allowing benzene, a carboxylic acid and molecular oxygen to react with each other in the presence of a catalyst comprising (A) palladium, (B) at least one element selected from elements of groups IIIb, IVb, Vb and VIb of the periodic table, and (C) at least one element selected from elements of groups IIIa and IVa of the periodic table. Preferably, element (B) is selected from elements of group VIb of the periodic table, and element (C) is contained in a metal oxide form in the catalyst. The catalytic activity can be maintained at a high level, and a phenyl ester is stably produced. The phenyl ester can be converted to phenol by a conventional procedure.
