Summary
Solute/water interactions in a series of diol solutions have been investigated by 1H NMR. Strong hydrogen bonding between water and alcohols that are more basic than water is thought to result in lower chemical shifts of water protons compared to the case of pure water. This is attributed to a greater degree of covalent character in the hydrogen bonding between water and the more basic diols. The inductive effect of the methyl group and longer chain alkyls is observed to increase basicity in ethylene glycol, propylene glycol, and 2,3-butanediol solutions. A correlation between the glass-forming ability of the diol solutions and the stronger hydrogen-bonding solutes (i.e., stronger bases) is developed, with 2,3-butanediol best promoting glass formation at the lowest concentrations.
