Reaction Steps

3.5 g of boric acid was heated in 150 ml of ethylene glycol at 150° C. for 30 minutes, in a 500 cc flask equipped with a reflux condenser. 25 g of hexamethylenetetramine and 21 g of 2,6-bis (1,1-dimethylethyl)phenol were then added and the solution maintained at 148-150° C. for 15 minutes. After cooling to 125° C. at which stage the first crystals appeared, 150 ml of H2SO4 (30% 0 was added and stirring was continued for another 30 minutes. The resulting slurry was filtered and washed with warm water. After drying, 22 g of 3,5-bis (1,1-dimethylethyl)benzaldehyde was obtained.
