Resumo: New complexes of lanthanides maleates were synthesized by the stoichiometric reaction between maleic acid and lanthanides hydroxycarbonates. The complexes were evaluated by a variety of techniques such as thermogravimetry and derivative thermogravimetry (TGA/DTG), differential scanning calorimetry (DSC), simultaneous TGA-DSC, DSC photovisual (microscope coupled to DSC), Fourier transform infrared spectroscopy (FTIR), evolved gas analysis (EGA) using TGA-FTIR and power x-ray powder diffraction (PXRD). The results of the analysis of these compounds provide information related to the such as stoichiometry, thermal stability, degree of hydration, hydration enthalpies, the main evolved gases during pyrolysis, the coordination mode between metal and ligand and the PXRD results. This detailed study intends to contribute to the area of synthesis of lanthanide compounds, motivating the elaboration of other syntheses, survey of more properties of these compounds or future applications with different functionalities.

Os complexos foram avaliados por uma variedade de técnicas como: termogravimetria e termogravimetria derivada (TGA/DTG), calorimetria exploratória diferencial (DSC), TGA-DSC simultânea, DSC-fotovisual (microscópio acoplado ao DSC), espectroscopia infravermelho com transformada de Fourier (FTIR), análise dos gases liberados (EGA por TGA-FTIR) e difração de raio X pelo método do pó (DRXP). Os resultados das análises destes compostos ofereceram informações relacionadas com a fórmula geral, estabilidade térmica, grau e entalpia de hidratação, os principais gases liberados durante a pirólise, o modo de coordenação entre metal e ligante, os sítios de coordenação dos ligantes e os padrões de difração. Este estudo detalhado pretende contribuir para a área de síntese de compostos de lantanídeos motivando a elaboração de outras sínteses, levantamento de mais propriedades destes compostos ou futuras aplicações com diferentes funcionalidades.Submitted by Luciana Ferreira (lucgeral@gmail.com) on 2020-09-17T11:01:50Z No. of bitstreams: 2 Tese - Bruna de Araújo Costa - 2020.pdf: 2796082 bytes, checksum: 2e9848ad16b94b2d2a2880cbc7c96b18 (MD5) license_rdf: 811 bytes, checksum: e39d27027a6cc9cb039ad269a5db8e34 (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2020-09-17T15:02:37Z (GMT) No. of bitstreams: 2 Tese - Bruna de Araújo Costa - 2020.pdf: 2796082 bytes, checksum: 2e9848ad16b94b2d2a2880cbc7c96b18 (MD5) license_rdf: 811 bytes, checksum: e39d27027a6cc9cb039ad269a5db8e34 (MD5)Made available in DSpace on 2020-09-17T15:02:37Z (GMT).
