“…Knowing their properties can help control, reduce or even eliminate such ions. Thus, the study and characterization of chelating has had an increasing role in this direction (OLIVEIRA et al, 1993;MIYANO et al, 1993;RASERA et al, 1995;MARQUES et al, 1997). In recent article Bariccatti, Rosa e Oliveira (2004), summarizing the 1,4-bis (3-carboxy-3-oxo-prop-1-enyl)benzene (bisbp) whose structure (figure1) indicates a possible application in the study of complexation of metal ions.…”

No presente trabalho, temos em foco um estudo de caracterização teórica do 1,4-bis (3-carbóxi-3-oxoprop-1-enil) benzeno, que é um alvo recente de estudos experimentais com potencialidade complexante de íons metálicos. Nosso estudo inclui cálculos de propriedades elétricas e propriedades ópticas lineares e não lineares (polarizabilidade e hiperpolarizabilidade). Por ser uma molécula relativamente grande e com muitos átomos de carbono, os cálculos foram limitados aos métodos HF (Hartree-Fock), DFT (B3LYP, BPE) e MP2 (Teoria de Perturbação de Möller-Plesset em segunda ordem). Uma vez que esses cálculos são os primeiros da literatura, esperamos contribuir para a caracterização de fato deste composto. Palavras-chave: Ácido 1,4-bis (3-carbóxi-3-oxo-prop-1-enil) benzeno.

ResumoIn the present paper we have a focus in a study the theoretical characterization of the 1,4-bis (3-carboxy-3-oxo-prop-1-enil) benzene acid, which is a recent target of experimental study with potentiality complexant of metal ions. Our study includes calculations of electric properties and optical linear properties and optical nonlinear (Polarizability and Hyperpolarizability). Because of being a relatively big molecule and with many atoms of carbon the calculations restricted the methods HF (Hartree-Fock), DFT (B3LYP, BPE) and MP2 (Möller-Plesset Perturbation Theory second order). Since it seems to these calculations to be the first one of the literature, we hope to contribute to the characterization in fact of this compound.

“…The X-ray powder patterns showed that all the compounds were obtained in amorphous state. The amorphous state is undoubledly related to the low solubity of these compounds, as already observed for compounds with other phenylsubstituted derivate of BP [8,13].…”

Solid state compounds M-2-Cl-BP, where 2-Cl-BP is 2-chlorobenzylidenepyruvate and M represents Al, Ga, In, and Sc were prepared. X-ray powder diffractometry, infrared spectroscopy and simultaneous thermogravimetry-differential thermal analysis (TG-DTA), have been used to characterize and to study the thermal behavior of these compounds. The results provided information concerning the stoichiometry, crystallinity, thermal stability and thermal decomposition of the compounds.

Este trabalho reporta o estudo de compostos binários do dicarboxilato 1,4-bis(3-carbóxi-3-oxo-prop-1-enil)benzeno, C6H4(-CH=CH-CO-COO-)2 , com os cátions metálicos Ag+ e Pb2+, obtidos a partir de soluções aquosas do ligante e dos nitratos dos cátions metálicos, em proporções estequiométricas. Para a caracterização e o estudo do processo de decomposição térmica desses compostos foram empregadas Espectrofotometria de Absorção na Região do Infravermelho com Transformada de Fourier (FT-IR), Análise Elementar (C, H), Complexometria com EDTA, Termogravimetria (TG) e Calorimetria Exploratória Diferencial (DSC).
