Reaktionsbedingungen

Temperatur: 100 °C

Versuchsvorschrift

206 g (1 mole) of p-tert-octylphenol, 59.0 g (1.57 moles) of 80% paraformaldehyde and 5.0 g of oxalic acid dihydrate were reacted under water reflux (100° C.) for 10 hours in a glass reactor to form a reaction intermediate. Ten hours after the initiation of the reaction, 89% of the used formaldehyde was consumed,and 1.32 moles of the formaldehyde added to 1.0 mole of p-tert-octylphenol. Phenol (70.5 g; 0.75 mole) was added to the reaction intermediate, and reacted at 100° C. for 3 hours. The reaction mixture was dehydrated by heating it to 165° C. under atmospheric pressure and then under reduced pressure to give a pale-colored p-tert-octylphenol/phenol/formaldehyde co-condensate.
