Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- Published 1993
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Data was published in a peer reviewed publication.
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Water and an organic were brought into equilibrium at a given temperature in a thermostat, and samples of each layer were removed with a syringe for analysis. To determine the amount of water in the organic layer sample, a weighed quantity of a solvent such as acetonitrile was added and the ratio of the water to the acetonitrile peak was measured with a Gow-Mac Series 550 thermal conductivity GC, a60ft by 2.2-mm-internal-diamet8rcolumn, Chromosorb 101 packing, and a Hewlett-Packard 3390A recorder-integrator.
- GLP compliance:
- no
- Type of method:
- flask method

- Water solubility:

- Conclusions:
- Interpretation of results (migrated information): other: partially miscible (0.1 mass %)
Octanal was only partially miscible (0.1 mass %) over the temperature range from 0 to 90°C. - Executive summary:
Water and an organic were brought into equilibrium at a given temperature in a thermostat, and samples of each layer were removed with a syringe for analysis. Octanal was only partially miscible (0.1 mass %) over the temperature range from 0 to 90°C.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
