Diazapolyoxamacrobicyclic compounds form ex-ceptionally stable complexes in organic nonpolar solvents by enclosing certain cations in the tri-dimensional cavity. In the present work, by using hydrogen bonding properties of chloroform.Tetraoxa-1,10-diazabicyclo(8.5«5) eicosane(2.1.1),...

Current densities from 40O Am to 1000 Am were used to investigate the electrowinning of cobalt from sulfate solutiaiie. The cell used was a cylindrical beaker of 1000 ml capacity. Two lead anodes and one stainless steel cathode were used as - electrodes. The cathode was prepared electrolytically...
