Details on results:
During this study the water solubility of cobalt boron beodecanoate at 20 °C and at 37 °C were determined using the flask method and was found to be 1897.9 mg/L at 20 °C (after 144 hours of shaking) based on a mesured concentration of 417.5 mg Co/L and 1136.5 mg/L at 37 °C (after 144 hours of shaking) based on a measured concentration of 250.0 mg Co/L.
Conclusions:
Interpretation of results: soluble (1000 - 10000 mg/L)During this study the water solubility of cobalt boron beodecanoate at 20 °C and at 37 °C were determined using the flask method and was found to be 1897.9 mg/L at 20 °C (after 144 hours of shaking) based on a measured concentration of 417.5 mg Co/L and 1136.5 mg/L at 37 °C (after 144 hours of shaking) based on a measured concentration of 250.0 mg Co/L.
