Determination of sorbate and benzoate in beverage samples by capillary electrophoresis - Optimization of the method with inspection of ionic mobilities
(ELSEVIER SCIENCE BV, 2008)
The aim of this study was to develop a fast capillary electrophoresis method for the determination of benzoate and sorbate ions in commercial beverages. In the method development the pH and constituents of the background ...
Synthesis, characterization and thermal behaviour of solid-state compounds of benzoates with some bivalent transition metal ions
(Sociedade Brasileira de Química, 2007-04-01)
Solid-state MBz compounds, where M stands for bivalent Mn, Fe, Co, Ni, Cu and Zn and Bz is benzoate, have been synthesized. Simultaneous thermogravimetry and differential thermal analysis (TG-DTA), differential scanning ...
Thermal decomposition of solid state compounds of lanthanide and yttrium benzoates in CO2 atmosphere
(Editora Unesp, 2008-01-01)
Foram sintetizados no estado sólido os compostos Ln-Bz, onde Ln representa lantanídeos trivalentes e Bz benzoato. Análise termogravimétrica e análise térmica diferencial (TG/DTA) foi usada para estudar a decomposição térmica ...
Physicochemical parameters involved in the lethal toxicity of N,N-[(dimethylamino)ethyl]-4-substituted benzoate hydrochlorides: A QSAR study
(Elsevier B.V., 1997-01-01)
A set of sixteen para-substituted N,N-[(dimethylamino)ethyl] benzoate hydrochlorides structurally related to procaine was synthesized. The apparent partition coefficients were determined by either shake-flask or HPLC methods ...

Crystal structure of zwitterionic 4-(ammoniomethyl)benzoate: a simple molecule giving rise to a complex supramolecular structure
(2014)
The asymmetric unit of the title compound, C8H9NO2 H2O consists of an
isolated 4-(ammoniomethyl)benzoate zwitterion derived from 4-aminomethylbenzoic
acid through the migration of the acidic proton, together with a ...
