Versuchsvorschrift
Phenol (141 g; 1.5 moles) and 2.5 g of oxalic acid dihydrate were added to the resol layer, and the mixture was heated to perform co-condensation reaction of the p-tert-octylphenol resol with phenol. While distilling off the resulting water and volatile matter under atmospheric pressure and then under reduced pressure, the reaction mixture was heated to 160° C. to give 358 g of a pale yellow p-tert-octylphenol/phenol/formaldehyde co-condensate having a softening point of 85° C.
