Photodegradation

The degradation of n-butyl acetate in air by reaction with OH-radicals was experimentally determined (Kwok & Atkinson, 1994; cited in AOP v1.92). The overall OH rate constant was determined to be 4.9 E-12 cm³/molecule*sec. The half-life was calculated to be 3.3 days (24 -h d; 0.5 E+06 OH/cm³).

 

Hydrolysis

n-Butyl acetate will hydrolyze slowly. Using HYDROWIN (v2.00), the hydrolytic half-life was estimated to be 78 d at pH 8 and 2 years at pH 7 (ECT, 2009).
