Determination and prediction of Kow and dimensionless Henry's constant (H) for 6 ether compounds at several temperatures

The octanol–water partition coefficient (Kow) and air–water partition coefficient (Kaw) as well as the dimensionless Henry's constant (H) are used to calculate the transport and fate of chemicals in the environment or eco-system. In this work, the Kow and the H were measured for 6 ether compounds; di-n-butyl ether (DBE), di-isopropyl ether (DIPE), tert-butyl ethyl ether (ETBE), tert-butyl methyl ether (MTBE), propyl vinyl ether (PVE) and tert-amyl methyl ether (TAME) at 4 different temperatures. The Kow was directly measured by using a conventional slow stirring (SS) method, while the H was measured using headspace gas chromatography (HSGC). Additionally, the measured Kow and H values were compared with the predicted values by the fragment constant method or HENRYWIN program approaches.
