The 8th International Congress on Ionic Liquids” (COIL-8) was held in Beijing, China on May 13-17, 2019; this year named: Ionic Liquids for Green World! COIL, the most influential international congress in the field of ionic liquids. Our group was there presenting the newest research results, entitled: „Highly Efficient Synthesis of Levulinates from α-Angelica Lactone, Catalysed with Lewis Acidic Trifloaluminate Ionic Liquids Supported on Carbon Nanotubes” and „Water-Tolerant Trifloaluminate Ionic Liquids: New and Unique Lewis Acidic Catalysts for the Organic Synthesis.
