Radiochemical stability of the dicyclohexano-18-crown-6 ether (DCH18C6): Synthesis and tests in radioactive medium of the DCH18C6 radiolytic products

Draye, Micheline,Favre-Reguillon, Alain,Chomel, Rodolph,Faure, Rene,Guy, Alain,Foos, Jacques,Lemaire, Marc

, p. 183 - 197 (2007/10/03)

The cis-syn-cis isomer of the dicyclohexano-18-crown-6 ether (DCH18C6) was subjected to hydrolysis and radiolysis with a 137Cs gamma source, at different doses of irradiation. The cis-syn-cis DCH18C6 radiolytic products previously identified [1], were synthesized in their different configurations. These radiolytic products, all of cis configuration, were tested on aqueous synthetic solutions of spent nuclear fuels. Experiments in radioactive medium showed that, under continuous extraction conditions, the cis-syn-cis DCH18C6 radiolytic products cannot perturb a reprocessing process using the DCH18C6 as selective extractant. Good prospects for the application of DCH18C6 to spent nuclear fuel reprocessing were therefore demonstrated. An X-ray crystallographic study of the DCH18C6 cis-syn-cis-isomer with uranyl nitrate was investigated. Elsevier,.

Bis-Cyclohexyl-Crown-Ethers as Allosteric Carriers

Costero, Ana M.,Rodriguez, Santiago

, p. 6265 - 6272 (2007/10/02)

Several bis-cyclohexyl-crown-ethers have been synthesized and used as carriers for alkaline cations.These compounds should all show negative allosteric cooperativity, but only 1 exhibits an odd cation transport behavior across the liquid organic membranes. Key words: Allosteric cooperativity; cation transport; crown-ethers; Na(1+)-K(1+)-ATPase; biological model.

STEREODESIGN OF CROWN ETHERS. I. SYNTHESIS AND (13)C NMR STUDY OF TRANS- CYCLOHEXANOCROWN ETHERS

Samoshin, V. V.,Zelenkina, O. A.,Subbotin, O. A.,Sergeev, N. M.,Zefirov, N. S.

, p. 413 - 418 (2007/10/02)

A series of trans-cyclohexanocrown ethers were synthesized by the intermolecular cyclization of polyethylene glycol trans-2-hydroxycyclohexyl ethers with the ditosyl derivatives of polyethylene glycols.A complete assignment of the signals in the (13)C NMR spectra was made for the obtained compounds.

CATALYTIC HYDROGENATION OF DIBENZO-18-CROWN-6 AT METALS OF THE PLATINUM GROUP

Gurskii, R. N.,Istratova, R. V.,Kirova, A. V.,Kotlyar, S. A.,Ivanov, O. V.,Luk'yanenko, N. G.

, p. 543 - 547 (2007/10/02)

The hydrogenation of the aromatic rings in dibenzo-18-crown-6 is accompanied by hydrogenolysis of the carbon-oxygen bonds of the polyether ring.The selectivity of hydrogenation depends on composition of the solvent, the nature of the catalyst, the temperature, the hydrogen pressure, and other factors.Rhodium and ruthenium catalysts exhibit the highest activity in the reaction: in water, Ru > Rh > Pt, Pd; in 2-propanol, Rh >> Ru > Pt > Pd.The hydrogenation and hydrogenolysis are concurrent reactions, and the former is favored by high pressure.
