Abstract
α,α′-Diaminoadipic acid-tetra(methylene phosphonic acid) was synthesized from diethyl α,α′-dibromoadipate via the Gabriel addition,hydrolysis and the Mannich reaction.The structures of the product and intermediates were characterized by MS,1HNMR,13CNMR,IR and elemental analysis.The results indicated that the overall yield of the target compound was 30.6%.The basis was established for the development of a new phosphono-carboxylic acid compound used as a water treatment chemical.
