• It was found that reaction products from amines and epoxides were suitable to be used for brighteners in zincate baths.A typical synthetic process was a reaction of 1mol of ethylene diamine with 1mol of epichlorhydrin with no addition of water at 80-120°C. As for brightener, 50% aqueous solution of the above reaction product was used.The reaction product was a polymer, which was yellow colored and soluble in water, but insoluble in alcohols or ethers. During the reaction, epoxy group was converted into hydroxyl group, and chlorine in epichlorhydrin was converted into amine hydrochloride by dehydrochlorination.
