Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Endpoint:
partition coefficient
Type of information:
calculation (if not (Q)SAR)
Adequacy of study:
key study
Study period:
2004-11-28 to 2004-11-10
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Result is estimated based on the n-octanol solubility and the water solubility. The water solubility was determined as range as the substance hydrolyses.
Principles of method if other than guideline:
The partition coefficient is estimated from the quotient of the n-octanol solubility and the water solubility as the experimental methods are not applicable. The substance is a salt, so the flask-shaking method (e.g. OECD no 107) and the HPLC-methode were not applicable.
Type of method:
other: estimation based on solubility
Partition coefficient type:
octanol-water
Type:

Partition coefficient:

Partition coefficient:
<= -4.8
Temp.:
20 °C
pH:
1.3
Conclusions:
The partition coefficient (n-octanol / water) estimated from the quotient of the n-octanol solubility and the water solubility is equal or lower than 0.000016. The log Pow is equal or lower than minus 4.8.
Executive summary:

The partition coefficient is estimated from the quotient of the n-octanol solubility and the water solubility as the experimental methods are not applicable. The solubility of lithium bis(oxalato)borate in n-octonal at 20.0±0.4 °C was determined to be lower than 8.11*10 g/L. The solubility of lithium bis(oxalato)borate in water at 20.0±0.4 °C and pH 1.3 was determined to be equal or higher than 507 g/L and lower than 1015 g/L.

Thus, the partition coefficient (n-octanol / water) estimated from the quotient of the n-octanol solubility and the water solubility is equal or lower than 0.000016. The log Pow is equal or lower than minus 4.8. (NOTOX, 2004)

Additional information

The partition coefficient is estimated from the quotient of the n-octanol solubility and the water solubility as the experimental methods are not applicable. The solubility of lithium bis(oxalato)borate in n-octanol at 20.0±0.4 °C was determined to be lower than 8.11*10 g/L. The solubility of lithium bis(oxalato)borate in water at 20.0±0.4 °C and pH 1.3 was determined to be equal or higher than 507 g/L and lower than 1015 g/L.

Thus, the partition coefficient (n-octanol / water) estimated from the quotient of the n-octanol solubility and the water solubility is equal or lower than 0.000016. The log Pow is equal or lower than minus 4.8. (NOTOX, 2004)
