Research Abstract

The structure of clusters in ethanol-water binary solutions at x_E (ethanol mole fraction) <greater than or equal>0.2 is investigated by the mass spectrometric analysis of the clusters isolated from liquid droplets and X-ray diffraction measurements of intact solution. Average numbers of water molecules (N^a) of the ethanol m-mer hydrates (5<m<15) in the mixtures at 0.2<less than or equal>x_E<less than or equal>0.8 are found to be expressed by a function of water mole fraction (x_w) : Na^a={(m/4.2) -1} ^2 (x_w+0.85), suggesting that the fundamental structure of the ethanol polymer-hydrates is invariable in thie region. An inflection point of N^a was found at x_3<approximately equal>0.2. The radial distribution functions (RDFs) fromthe X-ray measurements demonstrated a decrease of linear hydrogen bonds at 2.8 * with increasing x_E, while keeping the strongest peak at 4.8 * in 0.4<less than or equal>x_E<less than or equal>1.0. On the basis of the composition analysis of the mass spectra and the concentration dependence of RDFs, we propose the most likely model of ethanol-water binary clusters formed in the region 0.2<less than or equal>x_E<less than or equal>0.8.
