Details on results:
During this study the water solubility of cobalt acetylacetonate at 20 °C and at 37 °C were determined using the flask method and was found to be 5160.1 mg/L at 20 °C based on a measured concentration of 1042.3 mg Co/L and 5842.4 mg/L at 37 °C based on a measured concentration of 1180.2 mg Co/L using the flask shaking method.
Conclusions:
Interpretation of results (migrated information): soluble (1000-10000 mg/L)
