Zusammenfassung:When organic molecules are dissolved in ionic liquids (which have no effective vapour pressure), the vapour-liquid equilibria (as measured by infrared spectroscopy of the gas phase) revealed significant deviation from Raoult's law for a wide range of perfume raw materials. Previously, we had demonstrated a positive deviation from Raoult's law, enhancing the vapour pressure of the organic components. Here we developed a designed strategy for the ionic liquids which induces a negative deviation from Raoult's law, hence depressing the vapour pressure of the organic solutes. We present a new technology based on delayed release of perfume raw materials from new-to-the-world binary ionic liquid mixtures.
