Abstract
The novel artificial carriers have been synthesized by introduction of lipophilic group of pyrrolidinomalonaldehyde and N-imidazolylmalonaldehyde.. These stable dipolar synthetic carriers were used for transport of metal picrates through a liquid membranes. The cation specificity of the transport was determined by the means of atomic absorption spectroscopy. Carrier properties of ylides were compared with N,N-dimethyldodecylamine N-oxide and DB18C6. The formation of complexes of ylides with some inorganic salts by the means of NMR spectroscopy, X-ray and potentiometric measurements of KS have been studied.
