Investigação das propriedades catalíticas da MOF URJC-1 ― uma abordagem DFT
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE QUÍMICAPrograma de Pós-Graduação em QuímicaUFMG, 2022-10-27)
In 2016, Leo et al. published their work on the synthesis, characterization and study of the catalytic properties of MOF URJC-1. Its material was tested against the Knoevenagel condensation reaction between benzaldehyde ...
Síntese e avaliação catalítica das zeólitas com estrutura BEA, MFI e MTW na reação de Knoevenagel
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2014-08-22)
The use of zeolites in basic catalysis is small, especially when compared to the numerous applications of material in their acid form. Inside this context, are even smaller the number of studies on the use of as-synthesized ...
Preparation of different basic Si-MCM-41 catalysts and application in the Knoevenagel and Claisen-Schmidt condensation reactions
(Academic Press Inc. Elsevier B.V., 2010-05-04)
In the present work, the basicity of three different Si-MCM-41 mesoporous materials, namely, (1) as-synthesized Si-MCM-41, (2) Si-MCM-41 modified by dispersing cesium oxide (Cs(2)O) and (3) Si-MCM-41 with anchored ...

Estudo de MOFs zeolíticas de imidazolato com Zn(II) e Co(II) e emprego na condensação de Knoevenagel
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2021-05-26)
A new segment of porous materials has emerged last years: metal organic frameworks (MOFs). Zeolitic imidazolate frameworks (ZIFs), a subclass of MOFs, are formed by metallic cations and imidazolates presenting similar ...
Surfactant containing Si-MCM-41: An efficient basic catalyst for the Knoevenagel condensation
(Applied Catalysis A: General, 2006)
Si-MCM-41 molecular sieves, which are largely used in a number of acid and redox catalyzed reactions, as reported by the literature, were used as basic catalyst for the Knoevenagel condensation. This reaction involves the ...
Mechanochemical synthesis, characterization and thermoanalytical study of a new curcumin derivative
(2020-01-01)
The curcumin is the major constituent of turmeric plant (Curcuma longa), which presents several biological activities such as antioxidant, bactericidal, anti-inflammatory and antitumor. An interesting strategy to improve ...
As-synthesized TEA-BEA zeolite: Effect of Si/Al ratio on the Knoevenagel condensation
(Elsevier B.V., 2015-01-15)
The zeolite with BEA structure has been obtained using different Al amounts in the presence of tetraethylammonium as a structure directing agent. The effect of the Si/Al molar ratio on the crystal size, morphology, yield, ...
