160 °C

A 5% aqueous solution of sulfuric acid was added to the resol to neutralize it to a pH of 6, and then the aqueous layer was removed. Subsequently, 112.8 g (1.2 moles) of phenol and 11.6 g of 5% aqueous solution of HCl were added and heated to perform condensation reaction between the resol of p-cyclohexylphenol and the phenol. While distilling off the resulting water and the solvent under atmospheric pressure and then under reduced pressure, the reaction mixture was heated to 160° C. over the course of 4 hours to give 300 g of a pale-colored p-cyclohexylphenol/phenol/formaldehyde co-condensate.
