DCE: 1,2-dichloroethane; oDCBz: o-dichlorobenzene; DCM: dichloromethane; CBu: 1-chlorobutane; CBz: chlorobenzene; BBz: bromobenzene; CF: chloroform; cHex: cyclohexane; Bz: benzene; TE: toluene; mX: m-xylene:. These diluents are lined up downwards from the high-polar DCE to the low-polar mX. Average values of in aqueous solutions. /mol−1 dm3. Average values evaluated at and expressed by /mol dm−3. Errors of all the values evaluated here were except for the CF system. Reference [2]. value at (I/mol dm−3) = 0.1. See [21]. Reference [8]. Concentration of HCl. Reference [1].
