Exploring Hydrogen Bonding in Ethylene Glycol \2013 Water Mixtures at 3 Different Concentrations

Ethylene glycol (EG) is used in the industry as a precursor in polyester fibres production, as a preservative in the cosmetic industry and as a cryoprotectant solvent, when mixed with water. The presence of EG in an aqueous mixture lowers its freezing point and increases its boiling point. Due to the presence of hydroxyl groups in EG structure, the molecules within this liquid form hydrogen bonding. Proposed investigation of these networks will enrich the existing understanding of the structural properties of this industrially important liquid. We also plan to probe the effect of presence of water molecules on EG hydrogen bonding network. Three different concentrations will be tested to gain insight into a correlation between macroscopic properties, which vary with different EG concentration and the local ordering.
