Tetradecanol was determined according ASTM E 1147. The
partition coefficient was determined to be logPow 5.5.
For calibration 20 -30 mg of the reference
samples and of thio urea (dead time determination) are weighed into a
100 ml volumetric flask and filled up to 100 ml of a methanol-water
mixture (80:20). This calibration mixture (L090443) is then analysed by
the reported chromatographic conditions.

Alcohols, C12 -14 was determined according OECD Gideline
117. The partition coefficient of Tetradecanol was determined to be
logPow 6.4 at 23 °C and a pH of 7.1.
The octanol-water partition coefficient of a commercial sample of
tetradecan-1-ol is 5.5 (by HPLC method)
A log n-octanol/water partition
coefficient of 5.5 was determined for tetradecan-1-ol in accordance with
ASTM E 1147. The result is considered to be reliable. The
log n-octanol/water partition
coefficient of the tetradecanol constituent of a multi-constituent
alcohol was determined to be 6.4 and a consistent literature value is
It is supported by a log Kow value of 6.03,
taken from a reliable reference source for partitioning data (Burkhard
et al., 1985) and is consistent with the trend across the homologous
series. This value taken from literature for pure alcohol and validated
across the series is used in exposure modelling.
Discussion of trends in the Category of
C6-24 linear and essentially-linear aliphatic alcohols:
As chain length increases, the free energy
required for a molecule to dissolve becomes less favourable for larger
molecules. The octanol-water partition coefficient increases with
molecular weight because each additional -CH2- group makes
the octanol phase more preferred over water in terms of relative
