A series of non-cyclic polyethers with different end groups and chain length were used for the extraction of lithium salt from aqueous into various organic phases viz. Chloroform, Carbon tetrachloride, 1,2-dichloroethane, to study the influence of structural variations within the extractant molecule upon the extraction selectivity and efficiency. The ionophores used were viz. DEG (I), DEGDME (I...

Cr(III), Co(II), Ni(II), Cu(II) and Zn(II) salts of 2-(4-nitrophenylaminocarbonyl)benzoic acid were characterized by physical, analytical and spectroscopic studies and checked for their  in-vitro antimicrobial activity against three bacterial strains, Mycobacterium smegmatis (Gram +ve), Escherichia coli (Gram -ve), Pseudomonas aeuroginosa (Gram -ve) and three fung...

mono and bis hexamethylenetetramine iron(iii) chloride, fe(n c ,h ) ci (i) and fe(n c ,h ) cl (ii) were synthesized by the reaction of iron(iii) chloride and hexamethylenetetramine (hmta) in chloroform. chemical analysis and spectral results show the coordination of hmta to the iron(iii). electronic transition spectra of compound i and i1 were also studied in coordinating and noncoordinating so...
