Transesterification of Vegetable Oils: a Review
(Sociedade Brasileira de Química, 1998-05)
The transesterification of vegetable oils with methanol as well as the main uses of the fatty acid methyl esters are reviewed. The general aspects of this process and the applicability of different types of catalysts (acids, ...
Polarographic and spectrophotometric behavior of some N-para-phenyl substituted benzamidines
(INST ORGANIC CHEM AND BIOCHEM, ACAD SCI CZECH REPUBLIC, 1991-12)
Five N-p-phenyl substituted benzamidines were studied by DC and DP polarography in a wide pH range. Coulometric results show that the overall processes are four-electron reductions. Logarithmic analysis of the waves indicate ...
Synthesis, electrochemical, and spectroscopic studies of novel S-nitrosothiols
(2001)
A series of S-nitrosothiol compounds, structurally related to the NO-donor S-nitroso-N-acetyl-D,L-penicillamine (SNAP) that contain amidin groups were synthesised by S-nitrosation of the corresponding thiols and characterised. ...
Estudos de QSAR de furanobenzoamidinas frente à Pneumocystis carinii, Candida albicans e Cryptococcus neofarmans.: síntese de análogos furânicos S-isotioureidos
(Universidade Federal de Minas GeraisUFMG, 2011-12-05)
This work presents the results obtained in the studies of docking and QSAR carried out with a group of bis cationic bisamidines against Candida albicans, Cryptococcus neofarmans andPneumocystis carinii. As well as synthesis, ...
Fine-tuning the assemblies of carbon nanodots and porphyrins
(Royal Society of Chemistry, 2018-09)
We present charge-transfer assemblies of electron accepting, pressure-synthesized carbon nanodots (pCNDs) and an electron donating porphyrin. Amidine derivatization of the porphyrin allows for hydrogen bonding interactions ...
Uso do ácido lipoico para obtenção de agentes antiglicantes
(Universidade Federal de Minas GeraisUFMG, 2017-07-25)
Glycation is a non-enzymatic reaction between reducing sugars and amino group of biomolecules, forming advanced glycation end-products (AGEs), which are associated with various pathological conditions such as atherosclerosis, ...
Flow chemistry applied to hazardous reactions, and fluorophores synthesis with photophysics studies
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2020-02-20)
Two distinct cases of continuous flow conditions applied to dangerous reactions are described. The first example is the continuous photooxygenation of a series of dienes that produces endoperoxides and / which are potentially ...
