Cinética da degradação térmica de antocianinas de alaybilí (Vaccinium floribundum Kunth) e macha-macha (Gaultheria glomerata (Cav.) Sleumer)Kinetic of thermal degradation of alaybilí (Vaccinium floribundum Kunth) and macha-macha (Gaultheria glomerata (Cav.) Sleumer) anthocyanins
(2022-01-01)
Fruits are natural sources of antioxidants, especially anthocyanins. However, these compounds are sensitive to certain environmental or processing factors such as temperature, and there are reports in the scientific ...
Characterization and kinetics of sulfide-oxidizing autotrophic denitrification in batch reactors containing suspended and immobilized cells
(IWA PUBLISHING, 2011)
Sulfide-oxidizing autotrophic denitrification is an advantageous alternative over heterotrophic denitrification, and may have potential for nitrogen removal of low-strength wastewaters, such as anaerobically pre-treated ...
Exploring chemical kinetics at home in times of pandemic: Following the bleaching of food dye allura red using a smartphone
(American Chemical Society, 2021-05-12)
In this communication, a remote experimental activity in chemical kinetics is described, taking into account the quantification based on the optical sensor of a smartphone. The objective pursued herein is to equip students ...
Kinetics and Mechanism of Gas-Phase Thermolysis Using Headspace-Gas Chromatographic Analysis
(Oxford University Press, 2001-02)
Headspace gas chromatography is employed in order to study the thermal decomposition reaction of gaseous di-tert-butyl peroxide (DTBP) in the 130°C to 160°C temperature range and in the presence of n-hexane as the internal ...
Kinetics of the Esterification of Maleic Anhydride with Castor Oil
(Plapiqui, 2011-03)
Kinetics reaction between castor oil and maleic anhydride without condensation and catalyst was studied. On the other hand, the products concentration, kinetics and thermodynamics parameters were determined using mathematical ...
