Importance of structural free space to the solvent power of water.

The contribution of structural free space to the solvent power of water was examined by a systematic modification of the geometric factor. Gaps and holes, available to foreign molecule occupation, are thought to be filled at low concentrations (max. 1 %) of aliphatic alcohols. The effect upon solvency reached approximately 10%, which suggests that spatial parameters affect solvent power. The results demonstrate the importance of solvent purity in the dissolution process.
