Little literature on the aspect of surfactants containing boron with long-carbon chain alkyls had been found.Using diethanolamine, boric acid, hexadecanol as starting materials, after a series of reaction such as vapour phase process bromizating, esterifying, alkylating, a new type of surfactants with boron RNB had been obtained. The structures of the compounds had been identified by elemental analysis, IR and HNMR.
