Description of key information
Hydrolysis
The hydrolysis was examined at the two different pH values 4.0 and 9.0 in the dark at different temperatures of 50 °C (± 0.5), 55 °C (± 0.5) and 67 °C (± 0.5). The hydrolysis reaction was carried out using a dark thermostat to avoid photolytic effects. Nitrogen was bubbled into the water for five minutes before the preparation of the solutions in order to exclude oxygen. The calculated half-lives of the hydrolysis are, 236 days (5659 hours) at temperature 25 °C and pH 4.0, 13 days (305 hours) at temperature 50 °C and pH 4.0. 54 days (1299 hours) at temperature 25 °C and pH 9.0 and 5 days (122 hours) at temperature 50 °C and pH 9.0.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
