Description of key information

Rate constant (by QSAR): 21.2E-12 cm-3.molecule.sec.

Key value for chemical safety assessment

Additional information

No measured photodegradation data is available for butylglycol acetate. The calculated Rate constant (for indirect photolysis) of 2 -butoxyethyl acetate is : 21.2 E-12 cm³/(molecule*sec) with a resultant predicted atmospheric half life of 6 hours. An alternative calculation method led to a predicted rate constant of 19.5 E-12 cm3/(molecule*sec).
