Natural plant extracts are valuable ingredients for a wide range of applications, particularly in the cosmetic or pharmaceutical industries or in the perfume or food industries. But the extraction of these natural compounds remains mainly carried out using volatile organic solvents (VOCs) and processes with significant environmental impacts. In...

This study is aimed at evaluating the potential of the conductor-like screening model for real solvents (COSMO-RS) in designing biphasic systems for the separation of natural compounds. This model was used to predict binodal curves and phases composition of organic biphasic systems containing deep eutectic solvents. The results obtained...

Most industrial extraction processes of perfumery plant rely currently on maceration or hydrodistillation techniques. In the former case, non-sustainable organic solvents such as hexane, heptane, petroleum ether and ethanol are usually employed. Hydrodistillation, on the contrary, rely only on water, but has a high energy consumption related to...

A study on the formation of ternary biphasic systems composed of heptane, 1-butanol or ethyl acetate and type III or type V deep eutectic solvents based on levulinic acid and choline chloride or thymol was carried. Binodal curves and densities and phase compositions of phases in equilibrium for seven systems are reported. The partition...
