Resumo: | It is possible to observe an increase related research for the synthesis of coordination compounds and crystal lattices using transition metals and organic binders due to their great potential applications. The aim of this study was to synthesize the compounds Phthalate, Isophthalate and Terephthalate of Cobalt and Manganese through the reaction of the metal carbonate in excess with their acids studied. The synthesized compounds are presented in the form of crystalline solids. These compounds were characterized using analytical techniques: Simultaneous Thermogravimetric and Differential Scanning Calorimetry (DSC-TG), Fourier Transform Infrared Spectroscopy (FTIR). Thermogravimetry Analysis coupled to Fourier Transform Infrared Spectroscopy (TG-FTIR) and Differential Scanning Calorimetry (DSC). From the TG-DSC curves was possible to evaluate the thermal stability and the dehydration mechanism as well’as the empirical formula of the compounds as CoFta ∙ 2.5H2O, CoIFta ∙ 5H2O, CoTFta ∙ 4,5H2O for cobalt compounds and MnFta ∙ 0.5H2O, MnIFta ∙ 2.5H2O and MnTfta for manganese compounds. Even through the infrared spectra (FTIR), it was also possible to suggest the metal-ligand coordination mode as bridge for all compounds synthesized. |

O objetivo desse trabalho foi sintetizar os compostos de Ftalato, Isoftalato e Tereftalato de Cobalto e Manganês através da reação do carbonato metálico em excesso com os respectivos ácidos estudados. Os compostos sintetizados se apresentaram na forma de sólidos cristalinos e foram caracterizados através das técnicas: Termogravimetria e Calorimetria Exploratória Diferencial simultânea (TG-DSC), Espectroscopia de Infravermelho por Transformada de Fourier (FTIR). Termogravimetria acoplada a Espectroscopia de Infravermelho por Transformada de Fourier (TG-FTIR), Calorimetria Exploratória Diferencial (DSC). A partir das curvas TG-DSC foi possível avaliar a estabilidade térmica e o mecanismo de desidratação, bem como a fórmula mínima dos compostos como sendo CoFta∙2,5H2O, CoIFta∙5H2O, CoTFta∙4,5H2O para os compostos de cobalto e MnFta∙0,5H2O, MnIFta∙2,5H2O e MnTfta para os compostos de manganês. Ainda através dos espectros de infravermelho (FTIR) foi possível sugerir o modo de coordenação entre metal-ligante como em ponte para todos os compostos sintetizadosSubmitted by Luciana Ferreira (lucgeral@gmail.com) on 2016-07-26T11:39:23Z No. of bitstreams: 2 Dissertação - João Paulo Santos Carmo - 2016.pdf: 2412305 bytes, checksum: 19777a4bdead74386cf88a869674700c (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2016-07-26T11:41:09Z (GMT) No. of bitstreams: 2 Dissertação - João Paulo Santos Carmo - 2016.pdf: 2412305 bytes, checksum: 19777a4bdead74386cf88a869674700c (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Made available in DSpace on 2016-07-26T11:41:09Z (GMT).

The aim of this study was to synthesize the compounds Phthalate, Isophthalate and Terephthalate of Cobalt and Manganese through the reaction of the metal carbonate in excess with their acids studied. The synthesized compounds are presented in the form of crystalline solids. These compounds were characterized using analytical techniques: Simultaneous Thermogravimetric and Differential Scanning Calorimetry (DSC-TG), Fourier Transform Infrared Spectroscopy (FTIR). Thermogravimetry Analysis coupled to Fourier Transform Infrared Spectroscopy (TG-FTIR) and Differential Scanning Calorimetry (DSC). From the TG-DSC curves was possible to evaluate the thermal stability and the dehydration mechanism as well’as the empirical formula of the compounds as CoFta ∙ 2.5H2O, CoIFta ∙ 5H2O, CoTFta ∙ 4,5H2O for cobalt compounds and MnFta ∙ 0.5H2O, MnIFta ∙ 2.5H2O and MnTfta for manganese compounds. Even through the infrared spectra (FTIR), it was also possible to suggest the metal-ligand coordination mode as bridge for all compounds synthesized. |
