Description of key information

Vinylcyclohexane is a very volatile substance. It has a vapour pressure of 1.94 × 103 Pa at 20 °C and 2.47 × 103 Pa at 25 °C. Furthermore, its water solubility of 15 mg/L is relatively low. The EPISuiteTM estimated half-lives for volatilisation from rivers and lakes are 1.076 hours and 99.76 hours (4.157 days), respectively. The Henry Law Constant for VCH is 0.141 atm × m³/mol (corresponding to 1.425 E+04 Pa x m³/mol; calculated from vapour pressure/water solubility). This indicates rapid volatilisation from water to air.
