Reaction Steps

To a 1 liter, 3 necked round bottomed flask equipped with a paddle stirrer, condenser, thermometer and heating source, were added 188.6 g (1 mole) of the 4-chloro-2,6-dimethylolphenol, followed by 10 g (0.11 moles) of oxalic acid and 220 g (2 moles) of catechol. To this were added 400 g of water. The reaction mixture was stirred and heated to 70° C. Solution occurred when the temperature reached approximately 60° C. Then, the reaction mixture was heated to reflux and held at reflux for 4 hours. After 1 hour at reflux, the product began to separate.
