Aqueous solutions of 2,2-dimethyl-l-propanol were studied as a model system for the p, T-dependence of the hydrophobic interaction at pressures up to 200 MPa and between 273 K and 403 K. The liquid/liquid phase separation of this alcohol in light and heavy water is described. As expected for aqueous solutions of hydrophobic substances, the solubility of the alcohol is larger in light than in heavy water. The p, T, c-dependence of the self diffusion coefficients and of the rotatoric mobility, as given by the deuteron spin lattice relaxation times, of the water and alcohol molecules are studied in the one phase region. The translational and the rotational mobility of the water molecules in the binary solution show at low temperatures the anomalous pressure dependence typical for neat water.
