“…The common drawback of all homogeneous catalytic reactions, the difficulties in phase separation and recovery and reuse of the catalysts, raised the application of various alternative solvents [3]. Amongst these systems, the use of ILs drew particular attention due to their many advantageous properties, such as a very wide liquid range, negligible vapour pressure, ability to stabilise metal complexes, great variability of the structure of cation and anion.…”

The use of carbon monoxide as a carbonyl source for the preparation of aldehydes, ketones and carboxylic acid derivatives in homogeneous catalytic reactions is a valuable tool in the synthesis of fine chemicals. Amongst immobilising agents for carbonylation catalysts, the application of ILs drew particular attention. Besides enabling catalyst reuse, the ionic liquid may influence the structure of catalysts or catalyst precursors, may affect the chemoselectivity of the reaction or may be capable of solubilising special substrates. The present chapter is intended to summarise the research carried out in the past 15 years involving carbonylation reactions of alkenes/alkynes and aryl/alkenyl halides in the presence of various nucleophiles, such as alcohols, water, amines and thiols.

Construction Kit for the Solvent Selection in Homogeneous Catalyzed ReactionsChoosing the right solvent for chemical syntheses is often the base for a successful large-scale implementation. Especially in homogeneous transition metal catalyzed reactions, the solvent can be the limiting factor in issues of catalyst recycling and product separation. This review presents possible solvent types for chemical synthesis and which tools can be used to select a suitable one. A view at new solvents will be taken, possible concepts of catalyst recycling will be explained and the concept of the green solvents will be discussed.

ILs have some beneficial properties such as environmentally friendly 24 , low vapor pressure 25 , non-flammable 26 , good thermal stability 27 , and wide electrochemical window 28 . In addition, many works have been performed to replace conventional organic solvents for metallic ions liquid-liquid extraction 29 .…”

Abstract. In decades, many research and mineral processing industries are using solvent extraction technology for metal ions separation. Solvent extraction technique has been used for the purification of precious metals such as Au and Pd, and base metals such as Cu, Zn and Cd. This process uses organic compounds as solvent. Organic solvents have some undesired properties i.e. toxic, volatile, excessive used, flammable, difficult to recycle, low reusability, low Au recovery, together with the problems related to the disposal of spent extractants and diluents, even the costs associated with these processes are relatively expensive. Therefore, a lot of research have boosted into the development of safe and environmentally friendly process for Au separation. Ionic liquids (ILs) are the potential alternative for gold extraction because they possess several desirable properties, such as a the ability to expanse temperature process up to 300°C, good solvent properties for a wide range of metal ions, high selectivity, low vapor pressures, stability up to 200°C, easy preparation, environmentally friendly (commonly called as "green solvent"), and relatively low cost. This review paper is focused in investigate of some ILs that have the potentials as solvent in extraction of Au from mineral/metal alloy at various conditions (pH, temperature, and pressure). Performances of ILs extraction of Au are studied in depth, i.e. structural relationship of ILs with capability to separate Au from metal ions aggregate. Optimal extraction conditon in order to gain high percent of Au in mineral processing is also investigated.
