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. publisher: Elsevier date: 2015 type: Article type: PeerReviewed identifier: Ghanem, O.B. and Papaiconomou, N. and Abdul Mutalib, M.I. and Viboud, S. and El-Harbawi, M. and Uemura, Y. and Gonfa, G. and Azmi Bustam, M. and Lévêque, J.-M.
