“…This indicates that recycling ChCl/urea can easily be done by evaporating the ethanol used for regeneration. There are also studies where ChCl/urea has been successfully recycled in different processes (Singh et al 2011;Azizi and Gholibegloa 2012;Lobo et al 2012). The ethanol can also be reused using fractional distillation.…”

A simple and inexpensive method for producing water-stable pulp fibre yarns using a deep eutectic mixture composed of choline chloride and urea (ChCl/urea) was developed in this work. Deep eutectic solvents (DESs) are eutectic mixtures consisting of two or more components that together have a lower melting point than the individual components. DESs have been previously studied with respect to cellulose dissolution, functionalisation, and pre-treatment. This new method uses a mixture of choline chloride and urea, which is used as a swelling and dispersing agent for the pulp fibres in the yarn-forming process. Although the pulp seemed to form a gel when dispersed in ChCl/urea, the ultrastructure of the pulp was not affected. To enable water stability, pulp fibres were crosslinked by esterification using polyacrylic acid. ChCl/urea could be easily recycled and reused by distillation. The novel process described in this study enables utilisation of pulp fibres in textile production without modification or dissolution and shortening of the textile value chain. An interdisciplinary approach was used, where potential applications were explored simultaneously with material development from process development to the early phase prototyping.

One-pot multicomponent synthesis of Betti bases (aminoalkyl naphthols) from aldehydes, b-naphthol, and secondary amines in deep eutectic solvent (DES) based on urea and choline chloride has been developed. A broad range of aminoalkyl naphthols can be obtained smoothly in good to excellent yield in biodegradable choline-chloride-based deep eutectic solvent, being compatible with functional groups and operationally straightforward. In addition, DES could be readily recycled at least four times without obvious loss of activity.

“…In continuation of our interest in the application of deep eutectic solvent in organic synthesis [46][47][48][49][50][51], in this paper, we present the biodegradable ionic liquid based on choline chloride as template, stabilizer, and reaction media for the synthesis of nano-Fe 3 O 4 under the mild reaction condition [52]. The magnetic nanoparticles Fe 3 O 4 were prepared by autoxidation of Fe 2+ in the presence of potassium nitrate in the DESwater solutions of varying DES to water ratios.…”

Abstract. The simple method of fabrication of crystalline superparamagnetic nanoferrite (Fe 3 O 4 ) particles using oxidative hydrolysis of Fe (II) salt in a deep eutectic solventwater mixture has been reported. The spectral properties of Fe3O4 nanoparticles were characterized by Fourier Transform Infrared (FTIR) spectroscopy; X-Ray Di raction (XRD) as well as Scanning Electron Microscopy (SEM) techniques were used to estimate the crystalline structure and particle size. The results of the studies revealed that this technique could be adopted to synthesize agglomerate-free superparamagnetic Fe 3 O 4 nanoparticles in a simple manner in deep eutectic solvent which may nd potential application in the biosensor and corrosion protective coatings.
