Resorcinol‐lactose resin was synthesized using phosphoric acid as the catalyst at 95°C. 13 C‐NMR measurements proved that the chemical reaction is initiated at the 4‐ or 6‐carbon position in benzene ring. Sample separation by size‐exclusion chromatography (SEC) technology indicated that the resin consists of reacting mixtures of oligomer of lactose, glucose, and galacose with resorcinol. The resin, using a by product of diary industry as a main component, could be potentially applied as a novel adhesive to the wood process industry. © 2002 Wiley Periodicals, Inc.
