Additional information

The adsorption/desorption study has not been conducted as the butenes category members can be expected to have a low potential for adsorption. The adsorption coefficient has been calculated according to the appropriate equation in the TGD (EC 2003) for each of the isomers. The estimated adsorption coefficient, Koc, of 2-butene is 97.7, of but-1-ene is 109.6 and of 2 -methylpropene is 117.5.
