Data were described using empirical expressions to determine other physical-chemical properties, such as molecular volume, standard molar entropy, and lattice energy. Moreover, acute toxicity tests toward Scenedesmus quadricauda (green algae) and Vibrio fischeri have been conducted. The high values obtained for the 50 effective concentration (EC50) indicated that these new ionic liquids can be considered eco-friendly. © 2015 Elsevier B.V.
