EC number: 932-235-8
CAS number: -
INPUT DATA USED:
Molecular weight 172.3
Data temperature 25 deg C
Log Kow 4.72
Water Solubility 8 mg/l
Vapour pressure 0.39 Pa
Melting point 14 deg C
half life in air 22.9 h
half life in water and soil 720 h
The % environmental distribution calculated from the above parameters using the MacKay level 1 model is as follows:
The Level III program has also been used, with the default model, using the same input parameters.
The distribution between compartments obtained is as follows:
Release: To air To water To soil
% in air 77.9 0.0414 0.000334
% in water 2.67 36.6 0.0458
% in sediment 4.64 63.4 0.0794
% in soil 14.8 0.00784 99.9
The results reflect that the ultimate fate of 1-undecanol is dependent on its route of release into the environment. 1-Undecanol released to air
would partially precipitate to soil and water. There is relatively little movement between soil and water, because transfer via the air compartment is
very slow, for a substance of low volatility.
In water, the adsorption coefficient of 1-undecanol results in significant adsorption to sediment.
