Naphthenic acid properties are modelled using COSMO-RS solvation theory.
Log KOW, log H, and log KOA are estimated between −20 and 40 °C.
Log DOW and pH corrected log H are estimated for water for pH 0–14.
Log KOW and log H are estimated for water of increasing salinity.
Temperature and pH have a significant influence on partitioning.
