Description of key information

Stability In Organic Solvent
According to “ANNEX IX- STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF 100 TONNES OR MORE, study for Stability in organic solvents and identity of relevant degradation products is only required if stability of the substance is considered to be critical.
Solvents are substances that are capable of dissolving or dispersing one or more other substances. Organic solvents are carbon-based solvents (i.e., they contain carbon in their molecular structure).
The substance is Inorganic : Its functional groups indicate no solubility in common organic solvents.Stability in organic solvents is not considered critical.
It should be noted that this substance Potassium oxide is soluble in organic solvents such as ethanol and ether. The solubility of Potassium oxide in ethanol is approximately 38 g/100 g.
The study does not to be conducted if the substance is inoranic. (Ref. 1)
Its functional groups indicate no solubility in common organic solvents. Solubility in organic solvents is not considered critical. (Ref. 1)
Reactivity
Hygroscopic and reacts with water to form Potassium hydroxide.
Therefore testing for Stability in organic solvents does not need to be performed.
