Versuchsvorschrift

94 parts (1 mol) of phenol, 100 parts of water and 0.5 part of calcium hydroxide were charged in a kolben reactor equipped with a thermometer, stirrer, reflux condenser and dropping funnel, to which 114 parts (1.4 mols) of 37% formalin was dropwise added for 0.5 hour while stirring at 70° C., and the mixture was further stirred at the same temperature for 5 hours. 172.2 part (1.4 mols) of 3-amino-5-methylphenol was then added to the mixture, stirred at 120° C. for 1 hour, then heated at 150° C. and a reduced pressure of 40 torr for 1 hour to distil off water and further heated at 200° C. and a reduced pressure of 5 torr for 1 hour to reduce the unreacted monomers, thus obtaining a co-condensation resin of phenol.3-amino-5-methylphenol.formaldehyde.
