| Abstract: | 1H and 17O NMR of the dioxane (DO)-water system were studied. The complex equilibrium constants in this system were obtained from the 1H chem. shift variation of DO with its concentration With these equilibrium constants the equilibrium concns. of each species in all the samples were calculated The variations of 1H and 17O chem. shifts of water were analyzed with the fast exchange method. The 1H and 17O chem. shifts of free water in this system are linearly related to the natural logarithm of its concns. from which the degree of structural break of water by DO was evaluated. |
