Description of key information

From the water surface, tert-Butyl acrylate will rapidly evaporate into the atmosphere.
Henry's Law constant at 25 °C = 281 Pa*m3/mol

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
281
at the temperature of:
25 °C

Additional information

Henry's Law Constant was calculated according to TGD using the calculated Water solubility of 555 mg/L as estimated by SRC WSKOWWIN v1.41 and the measured vapour pressure of 7hPa at 18.5°C = 1097 Pa at 25°C (BASF SE, 2010). The constant was calculated to be 281 Pa*m3/mol at 25 °C indicating rapid evaporation of tert-butyl acrylate from the water surface into the atmosphere.
