Notes

Abstract: From literature data on partition coefficients and in some cases
solubilities in nonaqueous solvents we have been able to determine
Abraham descriptors for several series of organophosphorus
compounds including the dialkyl- and diaryl-phosphates (dialkylphosphoric
acids), trialkyl- and triphenyl-phosphates, dialkylphosphinic
acids and diphenylphosphinic acid, trialkyl- and triaryl-phosphine
oxides, and dialkylphosphites and triarylphosphines. Other organophosphorus
compounds studied were dimethyl methylphosphonate
and the flame retardant PBMP. For all these compounds, knowledge
of the Abraham descriptors enables partition coefficients to be predicted
for transfer from water to over 40 (wet) solvents. If the solubility
of a given compound in just one dry solvent (out of a list of 47
dry solvents) is available, then the solubility in all the other listed dry
solvents can be predicted through very simple equations.
