Procedure
880 grams of nonylphenol and 636 grams of phenol were heated at reflux with 420 grams of 50 percent aqueous formaldehyde and 21 grams of 30 percent sulfuric acid. The reaction product was distilled at atmospheric pressure to a temperature of 155° C., and then was further distilled under a vacuum of 28 inches to 165° C. The product was a hard, amber resin.
