چکیده
Abstract Pressurized planar electrochromatography (PPEC) of dansyl (DNS) derivatives amino acids in normal- and reversed-phase systems is presented. The results have been obtained for mobile phases with different acetonitrile (ACN) concentrations (0–85%). data show differences separation selectivity between high-performance thin-layer chromatography (HPTLC) PPEC systems. These originate from the electrophoretic effect which involved system, contrary to HPTLC one.

Manganese and Cobalt Salts of Para-Amino-Benzoic Acid Supported on Silica Gel as Oxidizing Catalysts
Para-Aminobenzoic acid is supported on silica gel via reaction of activated silica gel and p-aminobenzoic acid which is then converted to its manganese and cobalt salts. A mixture of the manganese and cobalt salts of the acid is used to catalyze allylic and benzylic alcohols to their corresponding carbonyl compounds in reasonable yields using oxygen or air. Reactions are clean and the catal...
متن کاملSimulation of the Silica Gel-Water Adsorption Chillers
A mathematical model describing the behaviors of current commercialized silica gel-water adsorption chillers is presented in this study. Comparing with the previous study, this model comprises (i) a realistic representation of the thermal mass of the associated piping materials and fins; (ii) a distributed modeling of the reactor bed for the sorption processes. The model is demonstrated on a tw...

متن کاملElectrochromatography in microchips packed with conventional reversed-phase silica particles.
This paper shows the applicability of a disposable and inexpensive microfluidic chip for electrochromatographic separations. The chip, recently developed by us for chip-based LC, was fabricated from PDMS incorporating conventional chromatographic RP silica particles (C18) without the use of frits. Three cephalosporin antibiotics were used to demonstrate the applicability of the chip-based chrom...
