Abstract

The solubility and the enthalpy of dicarboxylic acids have been determined in water at intervals between 278.5 and 543.5 K. At 298.15 K, the values derived were: Δsol H m (m∈=∈1.33 mol kg -1)∈=∈29.80 kJ mol-1for oxalic acid; Δsol H m (m∈=∈16.03 mol kg -1)∈=∈12.82 kJ mol-1 for malonic acid; Δsol H m (m∈=∈0.75 mol kg -1)∈=∈28.20 kJ mol-1 for succinic acid; Δsol H m (m∈=∈8.77 mol kg -1)∈=∈48.01 kJ mol-1 and Δsol H m (m∈=∈0.17 mol kg-1)∈=∈40.30 kJ mol-1 for glutaric and adipic acid respectively. The solubility value exhibits a prominent odd-even effect with respect to terms with even number of carbon atoms with the odd carbon numbers showing much higher solubility. Observations made in the atmospheres suggest that this odd-even effect may have implications for the relative abundance of these acids in aerosols. © 2008 Springer Science+Business Media B.V.
