RS-Freetext:
A Henry's Law Constant for the cis-isomer of 1,4-dichlorobut-2-ene of  515.2 Pa*m³/mol is estimated using a vapour pressure of 4.4 hPa and a  water solubility of 580 mg/l.
A Henry's Law Constant for the trans-isomer of 1,4-dichlorobut-2-ene of  316.5 Pa*m³/mol is estimated using a vapour pressure of 3.9 hPa and a  water solubility of 850 mg/l.
