Reaction Steps

To a 1 liter, 3 necked round bottomed flask equipped with a paddle stirrer, condenser, thermometer and heating source, were added 150 g (0.81 mole) of the 2,6-dimethylol-4-ethylphenol, followed by 9 g (0.1 moles) of oxalic acid and 181 g (1.64 moles) of catechol. To this was 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 for 4 hours. After 1 hour at reflux, the product began to separate.
