Gegenseitiger Austausch von Metallen in inneren Komplexsalzen

Use of Alternative Activators in 41° F. Polymerization Recipes

“…Differences in the stability of the complexes of various metals with ethylene dinitrilo tetraacetic acid or with nitrilo triacetic acid are possible (I, 2, [12][13][14][15][16][17][18][19][20][21]. In addition it is likely that the optimal concentration required for any metal other than iron may be far different than that used, in agreement with the data of Marvel et al (S, 9).…”

The Chemistry of Oxovanadium(IV)

“…The Schiff base formed from ethylenediamine and salicylaldehyde likewise complexes oxovanadium (IV) (7,27,47,118,273,274,335,365). Whereas this complex has a normal spin-only moment of 1.72 B.M.…”

“…Magnetic measurements have also been made on the complexes formed from the Schiff bases of salicylaldehyde and the amino acids glycine, alanine, and anthranilic acid (242). Perhaps the largest number of Schiff base complexes were prepared in the laboratory of Pfeiffer (273,274). Some were shown to be monomeric by molecular weight determination and many were obtained with smaller molecules (S) adduced.…”

Copper complexes in grassland herbage

“…(2) Extraction with an excess ofcomplex-forming agent followed by dialysis with water to provide qualitative information regarding the stability of copper complexes not extracted by procedure (1). This principle of competitive complex formation has been used by a number of workers to determine the order of affinity of a number of metal ions for an organic ligand (Pfeiffer, Thielert & Glaser, 1939;Ackernann, Prue & Schwarzenbach, 1949;Mellor & Maley, 1948) and of organic ligands for copper in an insoluble inorganic complex (Wain & Wilkinson, 1943).…”
