Reaction Conditions

Reaction Steps

Into a flask was charged 18.6 g (0.100 mole) 1-naphthylacetic acid, 93 ml. glacial acetic acid, and 8.1 g (0.100 mole) 37% formaldehyde. With stirring, 5.6 ml. (0.100 mole) 96% sulfuric acid was added and the mixture heated at a gentle reflux (110° C.) for about 21 hours. On cooling to room temperature and dilution with 200 ml. water, heavy deposition of solids took place. The polymeric solids were filtered, washed with water, re-slurried in 200 ml. boiling water, and filtered hot. The moist solids were dried in vacuo at 60° C. to give 17.3 g of the 1-naphthylacetic acid/formaldehyde polymer, a tan colored powder.
