Synthesis of new separating agents for nuclear materials

Synthetic methods for the preparation of complexing agents for the separation of radionuclide materials are described in this dissertation. Several series of new bifunctional anion-exchange resins were prepared by reaction of Reillex;Partial substitution of linear poly(vinylpyridine) with hydrophilic groups provided new water-soluble polymers which have potential for use in metal separation using ultrafiltration membranes.;For the cesium extraction from acidic nitrate media, several series of macrocyclic polyether compounds which have the oxygenated, aliphatic side arms were prepared. Acylation of dibenzo-18-crown-6 (or dibenzo-21-crown-7) and subsequent reduction provided new carbon atom-linked side armed polyether extractants. Several approaches to the synthesis of oxygen atom-linked side armed polyether extractants were explored with the model compound Sesamol. Although results of the model studies were promising, all attempts to extend the methods to the preparation of crown ethers were unsuccessful.
