Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Version / remarks:
- adopted on 27th July 1995: “Water Solubility”
- GLP compliance:
- not specified
- Type of method:
- flask method
- Key result
- Remarks on result:
- other: tert-butylbenzene (EC: 202-632-4) is insoluble in water.
- Remarks:
- tert-butylbenzene (EC: 202-632-4) is insoluble in water.
- Details on results:
- - Result of preliminary test
0.10 g sample was weighted and 100 mL water was added. Sample was not dissolved and phase separation occurred.
- Result of test
1) The result of preliminary test shows that the solubility of sample is smaller than 1 g/L. Three vessels were prepared and 0.5 g sample was weighed into each vessel, and 50mL water was added into each vessel. The vessels were equilibrated for 1d,2d and 3d respectively, with occasional shaking, after which the aqueous phase was analyzed using GC, and the pH values were test to be 4.59, 4.22 and 4.38. No tert-Butylbenzene was detected in any aqueous solutions. The detection limit is 5.8×10-4g/L.
2) The result is that the sample is insoluble in water. - Conclusions:
- tert-butylbenzene (EC: 202-632-4) is insoluble in water.
- Executive summary:
- Result of preliminary test
0.10 g sample was weighted and 100 mL water was added. Sample was not dissolved and phase separation occurred.

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.
