Conditions

Temperature
170 °C

Procedure

206 g (1 mole) of p-tert-octylphenol, 30 g (0.8 mole) of 80% paraformaldehyde and 6 g of oxalic acid dihydrate were condensed at 85° C. for 10 hours in a reactor. The reaction mixture was dehydrated by heating it to 170° C. to give a p-tert-octylphenol/formaldehyde condensate.

Workup
