Popis: | In this work, we present the synthesis of the of 2‑Hydroxy ethylammonium Lactate (HELa) and of 2‑Hydroxy ethylammonium Citrate (HECi) protic ionic liquids and their electric characterization by broadband dielectric spectroscopy. The complex permittivity e∗ and electrical conductivity σ∗ of HELa and HECi as a function of frequency and of temperature are obtained. The experimental results are discussed considering the type of anion in each ionic liquid. In the high frequency range (f > 1KHz), at room temperature (T ~25 °C), the HELa protic ionic liquid has been shown an electric conductivity higher than that formed by citrate anion. |
