【Abstract】 The complexes structure of sodium borate and resol phenol formaldehyde resin and their reaction mechanism are investigated by measuring pH and analyzing infrared spectroscopy. The results that the complexation reaction between sodium borate and resol phenol formaldehyde can be carrid out quickly in the aqueous solution at room temperature. The reaction can produce H + and decrease the pH in the resin solution. The reaction takes place in phenol hydroxyl groups and hydroxymethyl groups in adjacent position on the aromatic ring in the resin. The complexes is a hexatomic ring containing two oxygen atoms and one boron atom.更多还原
