Happy birthday, ethylammonium nitrate! The first widely known ionic liquid, studied by Paul Walden, turns 100 years old. Some important properties of EAN have been addressed properly for the first time. In their Communication on page 11640 ff., R. Ludwig, S. Verevkin et al. show that ethylammonium nitrate evaporates as contact‐ion pairs at low temperatures (<419 K). Above that temperature, neutral molecules dominate over ion pairs, resulting in the relatively low boiling point of 513 K.
