In the recent past, room-temperature ionic liquids (RTILs) are being explored for possible applications in nuclear fuel cycle. RTILs are being studied as an alternative to the diluent, n-dodecane (n-DD), in aqueous reprocessing and as possible substitute to high-temperature molten salts in nonaqueous reprocessing applications. This paper deals with the current status of the electrochemical research aimed at the recovery of actinides and fission products using room-temperature ionic liquid as medium. The dissolution of actinide and lanthanide oxides in ionic liquid media and the electrochemical behavior of the resultant solutions are discussed in this paper.

In this study, electroless nickel (EN) plating on acrylonitrile butadiene styrene (ABS) engineering plastic using room temperature ionic liquids (RTIL) was studied. Electroless plating is a fundamental step in metal plating on plastic. This step makes the plastic conductive and makes it possible to a homogeneous and hard plating without using any hazardous and unfriendly chemical such as palladium, tin, etc. In the industry there are many distinct chemical materials both catalysts and activation solutions for the electroless bath which is one of the most important parts of the process. In this study the effects of the ionic liquid, plating time, and sand paper size were investigated on electroless nickel plating. The etching and the plating processes were performed with environmentally friendly chemicals instead of the chromic and sulphuric acids used in the traditional processes. Experiments were carried out with and without ionic liquid, EMIC, 1-ethyl-3-methyl imidazolium chloride (C6H11N2Cl), and with 400, 500 and 800 grit sandpaper with the application of the sand attrition process and 70, 80, and 90 °C bath temperatures with 30, 60, and 90 minutes of deposition time. The surface morphology and the thickness of deposit analysis were performed using the Fischer scope X-Ray XDL-B System, X-ray Diffraction (XRD), and Scanning Electron Microscopy (SEM). Due to the results of the experiments and analysis, the electroless nickel plating on ABS plastic was a success. The best plating was obtained at 5.010 μm as the maximum plating thickness, at 90 min of plating time and 80 °C as the plating bath temperature for electroless nickel plating on ABS plastic whit the surface activated with 800 grit sandpaper using EMIC ionic liquid.

Intermolecular Reaction

Hexaalkylguanidinium-based room-temperature ionic liquids were investigated as solvents for the cyclopropanation of styrene with diazoacetates catalyzed by Rh2(OAc)4 or [Ru2(μ-OAc)2(CO)4]n. While the yields of the formed cyclopropanes are much lower compared to the reactions performed in dichloromethane, the diastereomeric ratio is not significantly affected by the change of the reaction medium. Immobilization of the catalysts is only partially successful. In contrast to this intermolecular reaction, the Ru-catalyzed formation of a β -lactam by an intramolecular carbenoid C-H insertion of an α-methoxycarbonyl-α-diazoacetamide occurs in high yield, similar to the Rh2(OAc)4-catalyzed reaction. The cis → trans isomerization of the resulting 1-tert-butyl-3-methoxycarbonyl-4-phenylazetidin- 2-one is accelerated in the ionic liquid N,N-dibutyl-N’ ,N’-diethyl-N’,N’-dihexylguanidinium triflate.
