Features of interaction acetate
and pivalate cerium (III) and europium (III) with monoethanolamine
Abstract
The composition of mixed-ligand complexes of
acetates, pivalates cerium (III) and europium (III) with monoethanolamine (MEA)
depends on the synthesis conditions and the nature of carboxylate ligand. Were
obtained solid complexes [Ln (Piv)3(MEA)x] (Ln =
Ce, Eu; HPiv = 2,2-dimethylpropionic (pivalic) acid, x = 1, 1.5) and
geles of hydroxocomplexes [Ln(Carb)n–x–y(NO3)x(OH)y(MEA)w(H2O)z]
(Ln = Ce, n = 4; Ln = Eu, n = 3; HCarb = Acetic acid (HAcet) or
HPiv). The values of the x, y, w, z coefficients depend on both
synthesis and heat treatment conditions. Products were characterized by IR
spectroscopy, NMR, elemental and thermal analysis, MALDI-MS. The method of
ESI-MS was used to characterize the processes occurring in the solutions.
