| Abstract: | In the present work, a comparative investigation of the extraction ability of some commercially available 18-membered crown ethers with respect to cesium cation from different media is carried out. It has been shown that, in the series of 18-membered crown ethers, di-tert-butyl-dibenzo-18-crown-6 has comparable extraction ability to that of the well-known analog di-tert-butyl-dicyclohexano-18-crown-6, which much readily available synthetically. |
