Polyaspartic acid was one kind of good scale inhibitor , which was synthesized with maleic anhydride and ammonia water.The optimum synthesis conditions were obtained by orthogonal test as follows : molar ratio of ammonia water to maleic anhydride was 1 , reaction temperature was 180 ℃, and reaction time was 60 min.Static scale for polyaspartic acid scale inhibition was evaluated.The results showed that polyaspartic acid had a good scale inhibition effect for CaCO 3 , and the inhibition rate reached 80.24%.
