Results and discussion
Partition coefficient
- Type:
- log Pow
- Partition coefficient:
- 4.5
- Temp.:
- 35 °C
- pH:
- 7
Any other information on results incl. tables
The determination was performed at 35 °C (temperature of the column) but the value obtained can be considered to represent the value at an unspecified, probably ambient temperature since no mention is made in the guidelines of the temperature at which the tabulated reference substances log Pow values were determined. Partition coefficients of the test and reference substances are assumed to vary with temperature in the same way.
Applicant's summary and conclusion
- Conclusions:
- The log Pow of the substance, Chlorocyclododecanone, was determined using OECD guideline 117 (HPLC) to be 4.5.
- Executive summary:
The Partition Coefficient n-octanol/water of Chlorocyclododecanone was determined by the Reverse Phase High Performance Liquid Chromatographic Method according to the OECD Guidelines for Testing of Chemicals, Method No. 117.
The result is:
Partition Coefficient n-octanol/water of Chlorocyclododecanone: log Pow = 4.5
