Capillary electrophoresis of o-phenylenediamine derivatives (quinoxalines) of dicarbonyl sugars
Dicarbonyl sugars were separated by capillary electrophoresis as o-phenylenediamine derivatives (quinoxalines). Tetrabutylammonium bromide was used as a modifier; n-arabino-2-hexosulose (n-glucosone), D-lyxo-2-hexostdose (D-gdaCtOSOnC), 7-deoxy-L-galacto-2-hexosulose and 5-hydroxy-2,3dioxohexanal served as standards. The separation procedure was optimized with respect to pH, buffer and solute c...
متن کاملFluoride release from fluoride varnishes under acidic conditions.
OBJECTIVE The aim was to investigate the in vitro fluoride release from fluoride varnishes under acidic conditions. STUDY DESIGN Poly(methyl methacrylate) blocks (Perspex, n=3 per group) were painted with 80 ± 5 mg fluoride varnish (n=10) and placed into artificial saliva for 30 min. Then, blocks were placed into either 1% citric acid (pH 2.27) or 0.3% citric acid (pH 3.75) solutions (n=3 per...
متن کاملGlycerol Selective Oxidation Under Acidic Conditions
Introduction Apart from the decline of fossil fuel energy resources, there is the added problem, recognised internationally, that fossil fuels are responsible for the greenhouse effect and global warming. Therefore, new alternative ways must be developed to satisfy not only energy needs and the production of chemicals but also for more benign effects on the environment. An approach already bein...
متن کاملTEMPO reacts with oxygen-centered radicals under acidic conditions.
In the presence of organic acids in organic media, 2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPO) reacts with peroxyl radicals at nearly diffusion-controlled rates by proton-coupled electron transfer from the protonated nitroxide.
متن کاملMetal Ion Prompted Macrocyclic Complexes Derived from Indole-2,3-dione (isatin) and O-phenylenediamine With their Spectroscopic and Antibacterial Studies.
A novel series of the complexes of the type:[M(TML)X]X2; where TML is a tetradentate macrocyclic ligand; M=Cr(III), Fe(III); X=Cl-, NO3-, OAc- has been synthesized by condensation of indole-2,3-dione (isatin) and o-phenylenediamine in the methanolic medium. The complexes have been characterized with the help of various physicochemical techniques like elemental analyses, conductance measurements...
