Additional information

Stability (abiotic transformation) endpoints generally consist of phototransformation and hydrolytic reactions. Given a vapor pressure of 0.25 Pa, volatilization of C4 acrylate to the atmospheric compartment could be expected. Based on technical service expert estimates, little release of C4 acrylate to the atmospheric compartment is expected during manufacture and polymerization. A modeled rate constant of 2.299E-011 cm³/ molecule∙s for reaction with hydroxyl radical indicates a projected atmospheric half-life of 16.7 hours. C4 acrylate has an experimentally determined hydrolytic half-life of 0.6049 years (221 days) at pH 7 and 25 °C. Process water at the manufacturing facility is treated using a combination of technologies. Reduction of C4 acrylate to <2 ppb (the limit of quantification) in the effluent water during treatment has been shown. No significant releases of C4 acrylate to aquatic systems are expected. Due to the lack of exposure to aquatic systems, hydrolysis is not expected to be relevant to the fate of C4 acrylate.
