The Synthesis of Cross-Linked Poly Aspartic Acid and Study on Control of the Calcium Carbonate Crystal Morphology

Abstract:

The intermediates polysuccinimide were synthesised by Maleic anhydride. Through the ring-opening reaction of polysuccinimide by ethylenediamine, which followed by alkaline hydrolysis and aminolysis, obtained cross-linked poly aspartic acid has a flaky structure. Using of its reticular, controling on the morphology of calcium carbonate crystals in the water. Compared with poly aspartic acid, the dissolution of the cross-linked product has been reduced by nearly 100 times. Static scaling inhibition experiments confirm that, cross-linked poly aspartic acid not only has the complexing capacity nature of the calcium in water, but also can control the growth of calcium carbonate scale to spherical, which has a special nature of lattice distortion.
