Description of key information

From the water surface, n-Butyl acrylate will slowly evaporate into the atmosphere.
Henry's Law constant at 25 °C = 21.9 Pa*m3/mol

Key value for chemical safety assessment

Additional information

Henry's Law Constant was calculated by Q(SAR) (SRC HENRYWIN v3.20) (BASF SE, 2015). The constant was estimated to be 21.9 Pa*m3/mol at 25 °C indicating slow evaporation of n-butyl acrylate from the water surface into the atmosphere.
