Adsorption/desorption

The soil sorption coefficient Koc of 3,7-dimethyl-6-octenal was calculated using EPIWIN v3.12, PCKOCWIN v1.66. The calculation yielded a log Koc of 2.16 and a Koc=147.7. Based on the result and taking into account the classification of Blume & Ahlsdorf (1993), a low sorption of 3,7 -dimethyl-6 -octenal onto soil organic matter is to be expected.

Henry´s Law constant

Henry's Law constant of 3,7-dimethyl-6-octenal was calculated using EPIWIN v3.12, HENRYWIN v3.10. The calculation yielded a value of 6.79 x 10E-4 atm x m³/mol (68.78 Pa x m³/mol) according to the bond method. Based on the results, 3,7 -dimethyl-6 -octenal can be considered as moderately to highly volatile from aqueous solution.
