3-methyl-5-phenylpent-2-enenitrile

Hydrolysis

Description of key information

The test item was found to be stable in the preliminary test. With respect to the guidelines a half-life of ≥ 2 year and a degradation rate of 0 min-1 could be assumed for environmental typical temperature conditions.

 

Key value for chemical safety assessment

Half-life for hydrolysis:

2 yr

at the temperature of:

50 °C

Additional information

The hydrolysis of the test item was assessed in accordance with the OECD guideline 111. The hydrolysis of the test item in different aqueous buffer solutions (pH = 4, 7 and 9) at 50 °C with test item concentrations of 40 mg/L was investigated using HPLC-UV. In this preliminary test, the test item was found to be stable at pH 4, 7 and 9, respectively. Reaction rate constants and half-lives could not be calculated because the test item undergoes no significant hydrolysis. With respect to the guidelines a half-life of ≥ 2 year and a degradation rate of 0 min-1 could be assumed for environmental typical temperature conditions.
