Study of isothermal decomposition of lanthanide mixed complexes with 2,2,6,6-tetramethyl-3,5-heptanodione and 1,10-phenanthroline

Isothermal decomposition kinetic of three lanthanide mixed complexes with the general formula of Ln(thd)3phen (where Ln=Nd, Sm or Er, thd=2,2,6,6-tetramethyl-3,5-heptanodione and phen=1,10-phenanthroline) has been studied in this work. The powders were characterized by their melting point, elemental...

Beschreibung
Zusammenfassung:	Isothermal decomposition kinetic of three lanthanide mixed complexes with the general formula of Ln(thd)3phen (where Ln=Nd, Sm or Er, thd=2,2,6,6-tetramethyl-3,5-heptanodione and phen=1,10-phenanthroline) has been studied in this work. The powders were characterized by their melting point, elemental analysis, FTIR spectroscopy and thermogravimetry. The isothermal TG curves have been recorded under the same conditions at 265-285, 265-285 and 250-270 deg C for Nd(thd)3phen, Sm(thd)3phen and Er(thd)3phen, respectively.
