EC number: 947-984-6 | CAS number: -
It was technically not possible to determine the partition coefficient of the resin part of the test item using the HPLC method. As the determination of the partition coefficient was not successful at neutral pH, an attempt to determine it at pH 10 was not made. The shake flask method and the estimation method could not be applied as no analytical method for the determination of the quantification of the test item in water was available. Hence, the calculation method was carried out for a representative structure of the test item. The calculation method was used for a estimation of the Pow of the test item. Calculation was performed using the KOWWIN™ v1.68 QSAR model. The Pow of the test item was calculated to be 18.07.
The log Pow of the xylene mixed isomers ranges from 3.12 to 3.2. The log Pow of m-xylene was reported as 3.2, for o-xylene as 3.12, for p-xylene the log Pow is 3.15, and for ethylbenzene the log Pow is 3.15. The log Pow for n-butanol is 0.88.
