The hydrogen bonding interactions between species in binary liquid systems can have a significant effect on the properties, especially in relation to the pure materials. Binary liquid systems composed of Brønsted acids and amines remain poorly understood. Understanding the interactions in these systems has become more important with the rising popularity of protic ionic liquids, which are formed from the equimolar combination of a Brønsted acid and a suitable base.We propose to study binary mixtures of ethanoic acid with two different tertiary amines at two different compositions, 1:1 and 2:1 acid:base, using the SANDALS Small Angle Neutron Scattering instrument. We wish to understand how the hydrogen bonding dynamics and proton exchange between species in these systems alter with composition, as well as with introducing a hydroxyl functional group to the amine.
