In order to investigate the effects of glycerol on the properties of water, the proton magnetic resonance of water-glycerol mixture has been determined in the absence and presence of electrolytes.
By adding glycerol into water, significant downfield shift was observed. This result suggests that glycerol would promote the intermolecular hydrogen-bonding of water.
The upfield shift of water proton resonance on the addition of structure breakers, KCI, KBr and KI, of which the structure-breaking ability increases in that order, was found to be more prominent in the presence of higher glycerol content. This effect was remarkable for the electrolytes which are well known as the effective structure breakers to water. These results suggest that glycerol apparently promotes the structure breaking effects of the electrolytes.
The apparent increases of the structure breaking effects of these electrolytes are explained in terms of the promotions of intermolecular hydrogen-bonding in water caused by glycerol.
