Determination and estimation of partitioning properties for phenylthio-carboxylates

A shake-flask method was used to determine the octanol/water partition coefficients (Kow) and the water solubilities (Sw). A batch method was used to determine the organic carbon-based sorption coefficients (Koc) on natural soils of 18 phenylthiocarboxylates. Linear relationships among these three properties were first reported, they provided a quantitative equation to predict all the partitioning properties of an unknown phenylthio-carboxylates from any of the measured properties. The LSER method have been extended to establish a series of correlation equations successfully, they were used to predict these partitioning properties more accurately.
