Abstract Attempts have been made to prepare some novel copper(I) nitrate, sulfate, and perchlorate complexes. Molar conductances of these complexes have been measured in organic solvents like acetonitrile (AN), acetone (AC), methanol (MeOH), N,N-dimethylformamide (DMF), N,Ndimethylacetamide (DMA), and dimethylsulfoxide (DMSO) at 298 K. The molar conductance data have been analyzed to obtain limiting molar conductances (λ0) and ion association constants (KA) of the electrolytes. The results showed that all these complexes are strong electrolytes in all organic solvents. The limiting ionic molar conductances (λo± ) for various ions have been calculated using Bu4NBPh4 as reference electrolyte. The actual radii for copper(I) complex ions are very large and different in different solvents and indicate some solvation effects in each solvent system

A new ion association technique was developed in our laboratory to demonstrate polyanions histochemically. The identification of the polyanions was effected in two steps: (1) the formation of a polyanion-quaternary ammonium complex following treatment with a quaternary salt and (2) subsequent formation of a red ion association complex with the quaternary moiety following treatment with ferric thiocyanate solution. Chemical studies indicated that the ion association complexes are cetyltrimethylammonium-hexathiocyanatoferrate (iii) and cetylpyridinium-hexathiocyanatoferrate (iii). These are red in color, very soluble in organic solvents such as chloroform, ethanol, methanol, acetone and xylene and insoluble in water.

Catalytically Active

Cellulose–TiO2 membranes with photocatalytic activity were prepared by non-solvent induced phase separation from cellulose solutions in ionic liquids or from cellulose acetate solutions in organic solvents followed by deacetylation.
