Versuchsvorschrift
206 g (1 mole) of p-tert-octylphenol, 60 g (0.64 mole) of phenol, 121.0 g (1.5 moles) of 37% formalin and 1.5 g of 35% HCl were condensed under water reflux for 10 hours. The reaction mixture was dehydrated by heating it to 160° C. under atmospheric pressure and then under reduced pressure to give a pale yellow p-tert-octylphenol/phenol/formaldehyde co-condensate having a softening point of 102° C.
