Under exploratory development (SEED) funding from the Strategic Environmental Research and Development Program (SERDP), ionic liquids composed of naturally-occurring anions were synthesized and evaluated as environmentally benign deicing fluids. Exothermic dissolution and low freezing point depression of water were promising. However, calculations of theoretical oxygen demand as well as toxicity appear to preclude these ionic liquids from 'drop-in' replacement deicing formulations.
