Protic ionic liquids (PILs), such as ethylammonium nitrate (EAN), are ionic compounds with low melting point that are prepared by combination of a Brønsted acid and base. As such they are characterised by the presence of protondonor and -acceptor sites, which contribute to develop a hydrogen-bonded network. Moreover, in the case of EAN, distinct mesoscopic order exists as a consequence of its inherent amphiphilicity. Such a structural complexity is deemed to increase upon mixing with another H-bonding active compound, such as methanol. In this presentation we will show the results from a study conducted taking advantage of the high complementarity of x-ray and neutron scattering, to probe the mesoscopic structure. The local order of these mixtures will also be investigated using Raman and IR spectroscopy data, to monitor the structural changes as a function of both concentration and temperature

Abstract
Protic ionic liquids (PILs), such as ethylammonium nitrate (EAN), are ionic compounds with low melting point that are prepared by combination of a Brønsted acid and base. As such they are characterised by the presence of protondonor and -acceptor sites, which contribute to develop a hydrogen-bonded network. Moreover, in the case of EAN, distinct mesoscopic order exists as a consequence of its inherent amphiphilicity. Such a structural complexity is deemed to increase upon mixing with another H-bonding active compound, such as methanol. In this presentation we will show the results from a study conducted taking advantage of the high complementarity of x-ray and neutron scattering, to probe the mesoscopic structure. The local order of these mixtures will also be investigated using Raman and IR spectroscopy data, to monitor the structural changes as a function of both concentration and temperatureI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
