Gas-solvent and water-solvent partition of trans-stilbene at 298Â K

We start with literature data on gas to solvent partition of trans-stilbene, as log K, for 52 solvents. The log K values can be converted into corresponding water to solvent partitions, as log P, through the stilbene gas to water partition coefficient, and lead, with four additional equations, to a set of 108 simultaneous equations that can be solved to yield descriptors for stilbene with a standard deviation of no more than 0.096 log units. This represents statistically the best analysis of stilbene solubility to date. The stilbene descriptors can be combined with equation coefficients to give predictions of stilbene gas to solvent partition and water to solvent partition for numerous dry solvents, wet (water saturated) solvents and ionic liquid solvents, as well as predictions of environmental and biological processes involving styrene.
