Description of key information
Dipotassium oxide/ Potassium oxide has low vapor pressure (3.03E-014 Pa) indicating significant amounts of Dipotassium oxide/ Potassium oxide are unlikely to be present in the atmosphere for photodegradation.
If released to air, a vapor pressure of 2.27E-016 mm Hg at 25 deg C (2.27E-016 mm Hg is equivalent to a vapour pressure of 3.03E-014 Pa) indicates significant amounts of Dipotassium oxide/ Potassium oxide are unlikely to be present in the atmosphere for photodegradation and therefore Dipotassium oxide/ Potassium oxide is not expected to be susceptible to direct photolysis by sunlight.
