Ionic liquids are novel solvents of interest as greener alternatives to conventional organic solvents aimed at facilitating sustainable chemistry. As a consequence of their unusual physical properties, reusability, and eco-friendly nature, ionic liquids have attracted the attention of organic chemists. Numerous reports have revealed that many catalysts and reagents were supported in the ionic l...

Ionic liquids can be considered as green solvents due to their very low vapor pressure and wide range of applications with unique physical and chemical properties. The potential of ionic liquids have been recognized worldwide. Scientists and engineers have been working in the advancement of preparation and applications of ionic liquid so that it can provide a range of options to industrialists ...

Ionic liquids (ILs) have recently been introduced as green solvents and potential substitute to volatile organic compounds. This is due to their negligible vapour pressure, high thermal stability, and large liquid phase range. Moreover, their physical and chemical properties can be tuned accordingly by proper choice of cations and anions. Thus, researchers suggest replacing conventional amine b...

The photophysics of a 3-hydroxychromone dye, 2-(2-furyl)-3-hydroxychromone (FHC) was explored in different types of protic solvents by steady-state and time-resolved fluorescence spectroscopy. FHC exhibits a dual emission, attributable to the excited normal (N*) and tautomer (T*) forms resulting from an excited state intramolecular proton transfer (ESIPT) reaction (N*-->T*). The ESIPT rate decr...

Supercritical fluids are increasingly being used and promoted at a laboratory and pilot scale to produce high value, natural bioactives from biologically based raw materials. Supercritical CO2 is overwhelmingly the solvent of choice for these operations, but is largely limited to the processing of dry raw materials and the extraction of low polarity, low molecular weight compounds. The use of c...
