Aqueous synthesis and properties of phosphono\|based malic acid/ acrylic acid, green water stabilizing agent (phosphoric content PO 3\| 4≤5%), was systematically investigated. Malic anhydride, acrylic acid and sodium hypophosphite, initiated by oxydol in aqueous solvent, were used as the feed stock in this synthetic reaction. The optimum conditions and material ratio was: M∶A=1.0∶1.0(mol ratio), reaction temperature 100 ℃, reaction time 2.5 h, initiate agent and cat. Weigh 30% and 0.3% of malic anhydride. The corrosion and scale\|inhibiting results show that the product possesses excellent properties of water stability.
