It was found that, within the scope of investigated data, the Sechenov constant is proportional to a hydrocarbon-specific parameter representing the size of the cavity in water needed to accommodate the dissolved molecule of the hydrocarbon. The proportionality coefficient has one value for n-alkanes, cycloalkanes, and alkylbenzenes, whereas for higher aromatics (including those with fused rings), a second value of the coefficient is indicated. The proposed model provides a framework for comparison of the data for various systems and helps in the recognition of systematic error. Evaluation of experimental solubility data and analysis of error propagation is given. 收起
