Abstract

Abstract : Calcium complexes of cyclic oligocarboxylic acids have been studied as models to understand how subtle changes in molecular structure lead to significant variation in inhibition ability for calcium carbonate deposition Abstract : Cyclic oligocarboxylic acids are the most commonly explored phosphate-free inhibitors for calcium carbonate scale deposition. The structural chemistry of calcium complexes of candidate inhibitors has the potential to give insight into inhibitor mode of action and design. We report a series of calcium compounds of cyclic oligocarboxylic acids of (1 α, 3 α, 5 α )-1, 3, 5, -cyclohexanetricarboxylic acid (CHTCA); cyclohexane-1, 2, 4, 5-tetracarboxylic acid (CHTTCA); 1, 2, 3, 4, 5, 6-cyclohexanehexacarboxylic acid (CHHCA); 1, 1-cyclohexandiacetic acid (CHDAA) and cis, cis, cis, cis -1, 2, 3, 4-cyclopentanetetracarboxylic acid (CPTCA) to understand the relationship between ligand stereochemistry and calcium ion coordination mode.
