Description of key information

In contact with water n-Butyl acrylate will hydrolyse slowly.
Half-life at pH 7 and 25 °C: 1100 d

Key value for chemical safety assessment

Additional information

In a hydrolysis study conducted by Ricerca Inc. (BAMM 1990), the half-life of 14C-butyl acrylate in water at pH 11 was determined to be approximately 243 minutes. There was less than 2 % hydrolysis of 14C-butyl acrylate at pH 3 and pH 7 during the 28 day period. Approximate hydrolysis half-life values for pH 3 and pH 7, calculated using initial and final 14C-butyl acrylate concentrations, were 2800 days at pH 3 and 1100 days at pH 7.

Therefore, the substance will hydrolyse slowly in contact with water under environmental conditions. Hydrolysis will not contribute significantly to the degradation of n-butyl acrylate under environmental conditions.
