dc.description.abstract | Solid state Ln-2-MeO-CP compounds, where Ln stands for light trivalent lanthanides (La, Ce, Pr, Nd, Sm, Eu, Gd) and 2-MeO-CP is 2-methoxycinnamylidenepyruvate, were synthesized in this work. Simultaneous thermogravimetry and differential thermal analysis (TG-DTA), differential scanning calorimetry (DSC), X-ray powder diffractometry, experimental and theoretical infrared spectroscopy and complexometry were used to characterize and to study the thermal behaviour of these compounds. The results led to information regarding the composition and stability of the isolated complexes. | pt_BR |
dc.description.resumo | Compostos Ln-2-MeO-CP no estado sólido, em que o símbolo Ln representa lantanídeos trivalentes (La, Ce, Pr, Nd, Sm, Eu, Gd) e 2-MeO-CP é 2-metoxicinamalpiruvato, foram sintetizados neste trabalho. As técnicas de termogravimetria e análise térmica diferencial simultâneas (TGDTA), calorimetria exploratória diferencial (DSC), difratometria de raios X, espectroscopia de absorção no infravermelho (espectros experimental e teórico) e complexometria foram usadas para caracterizar e estudar o comportamento térmico destes compostos. Os resultados informam sobre a composição e a estabilidade dos complexos isolados. | pt_BR |
