Description of key information

Koc = 2959 L/kg, log Koc = 3.47 at 25 °C (KOCWIN v2.00, log Kow method)
Koc = 436.8 L/kg, log Koc = 2.64 at 25 °C (KOCWIN v2.00, MCI method)

Key value for chemical safety assessment

Additional information

No studies investigating the adsorption/desorption characteristics of 1,7-octadiene are available. A calculation using KOCWIN v2.00 revealed log Koc values of 3.471 (log Kow method) and 2.64 (MCI method) (2013-0146-DKB). The corresponding Koc values are 2959 L/kg (Log Kow method) and 436.8 L/kg (MCI method).
