Log Kow of (1-methylethyl)-1,1'-biphenyl was determined in a pre-guideline study using a HPLC method similar to OECD TG 117. Similar results were obtained in a study following the principles of OECD TG 107 (Shake Flask Method).
Log Kow of
(1-methylethyl)-1,1'-biphenyl was determined in three independent
experimental studies (Mendoza/Dow 1981 - HPLC method, Addison 1983 -
shake flask method, Ozburn et al 1980 - shake flask method). Results of
the first two studies were close together (5.33/5.51 - two different
isomers and 5.2, respectively). Log Kow of the Ozburn study was 7. This
study was disregarded as experimental conditions were rather deviant
from guideline requirements and the result was two orders of magnitude
higher than the values of the other two studies. With the estimation
program KOCWIN v1.83 within US EPA EPISuite v4.11, a log Kow of 5.21 was
calculated that is in good agreement with the experimental values. A log
Kow of 5.33 was selected to characterise the substance as this value
represents the mean.
