Conc. based on:

test mat.

Temp.:

20 °C

pH:

>= 5.3 - <= 5.5

Details on results:

None detected - prelim solubility. Main test complete, <1 x 10-5 g/l as rhodium at 20.0 ± 0.5 °C, equivalent to <9.0 x 10-5 g/l of test substance at 20.0 ± 0.5 °C.

Water solubility of the test item has been determined to be less than 1.0 x 10 -5g/l of solution at 20.0 ± 0.5 °C based on monitoring of rhodium concentrations, equivalent to a tris(triphenylphosphine) rhodium (I) chloride solubility of less than 9.0 x 10 -5 g/l of solution at 20.0 ± 0.5 °C.

Conclusions:

Water solubility of the test item has been determined to be less than 1.0 x 10-5 g/l of solution at 20.0 ± 0.5 °C, based on monitoring rhodium concentrations, equivalent to a tris(triphenylphosphine) rhodium (I) chloride solubility of less than 9.0 x 10 -5 g/l of solution at 20.0 ± 0.5 °C.

Executive summary:

This is a GLP compliant, guideline study considered suitable for use as the key study for this endpoint. Water solubility of the test item has been determined to be less than 1.0 x 10-5 g/l of solution at 20.0 ± 0.5 °C, based on monitoring rhodium concentrations, equivalent to a tris(triphenylphosphine) rhodium (I) chloride solubility of less than 9.0 x 10 -5 g/l of solution at 20.0 ± 0.5 °C.

Additional information

O'Connor and Woolley (2010) is GLP compliant study following OECD TG 105 and is considered suitable for use as the key study for this endpoint.

Water solubility of the test item has been determined to be less than 1.0 x 10-5g/l of solution at 20.0 ± 0.5 °C equivalent to a tris(triphenylphosphine) rhodium (I) chlroide solubility of less than 9.0 x 10-5 g/l of solution at 20.0 ± 0.5 °C.

Infracor (2001) is a GLP complaint, guideline study considered suitable for use as a supporting study for this endpoint. The water solubility of Chloro-tris(triphenylphosphin)-rhodium(1) could not be determined because of hydrolysation.
