The main components DIPE and 2 -methylpent-2 -ene have a high Henry’s law constant at 20°C: the measured value for DIPE is 173 Pa m3/mol or 0.0709 (dimensionless). The estimated value for 2 -methylpent-2 -ene is 20000 Pa m3/mol or > 8 (dimensionless) using the HENRYWIN (v3.20) routine of Episuite. According to the TGD IR & CSA R7a (2008, p.191), chemicals with H values around 100 Pa m3/mol are considered to volatilise rapidly.

Using the HPLC method, log KOC for the reaction mass was determined in the range of 0.8 - 2.6. Strong binding to soil particles is only expected for a log Pow > 5 or log Koc > 4 and adsorption to sediment it not expected below a log Koc of 2.7 - 3 (ECHA, TGD IR & CSA, 2008, R7 p.154). The components of the reaction mass are thus not expected to strongly adsorb to soil or sediment
