The possibility of yttrium, gadolinium, and ytterbium electrodeposition from solutions of their triflates in different ionic liquids at 100°C was investigated. It was shown that these metals could be deposited on the cathode from electrolytes based on ionic liquids with quaternary ammonium cations, and these metals do not deposit from 1-butyl-2,3-dimethylimidazolium triflate. It was established that, in the case of butyltrimethylamonium triflate usage, metal deposition occurs on a copper electrode, and it does not occur on a platinum electrode, and in 1-butyl-1-methylpirrolidinium triflate, the reduction process is possible on both electrodes. Yb3+ reduction occurs step by step via Yb2+ formation. It was shown that the limiting stage of the cathode process is adsorption of a metal cation on the electrode.
The 1% CeO 2 , 9% La 2 O 3 /SiO 2 and 2% CeO 2 , 8% La 2 O 3 /SiO 2 catalysts show reliable efficiency in the OCM reaction, as well as stable work in the redox cyclic mode. Selectivity to C 2 products remarkably increases if preliminary reduction of the catalyst by a small amount of hydrogen is used.

Two series of imidazolium ionic liquids with the bis(trifluoromethylsulfonyl)imide anion were synthesized, which differ by the presence of a hydroxyl group at the ω-position of the alkyl substituent...
