Micellar Catalysis on Pentavalent Vanadium Ion Oxidation of D-Sorbitol in Aqueous Acid Media: A Kinetic Study

A review on the advancement of ether synthesis from organic solvent to water

“…Micelles behave as nano-reactors for metal based oxidation reactions such as Cr(VI), [21][22][23][24] Ce(IV), [25][26][27][28] Mn(VII), 29 V(V). [30][31][32] Dimethyl ether (DME) is the simplest ether, which can be synthesized from methanol dehydration over an acid support or from syngas conversion via a two step reaction with methanol as an intermediate. DME can also used as LPG, diesel fuel, etc.…”

Micelle catalyzed oxidation of propan-2-ol to acetone by penta-valent vanadium in aqueous acid media

“…The purpose of this work is a generic investigation into the elucidation of catalytic mechanisms. It is reported that micelles have effects on the rate of reactions [7][8][9][10][11][12]. Here, we report micellar catalysis of pentavalent vanadium ion oxidation of propan-2-ol in aqueous acidic media.…”

Effects of Surfactants on the Oxidation of Aromatic Azo Dyes

“…The values of activation parameters viz., Ea # , frequency factor Z, ∆S # , ∆H # , ∆G # are given in Table 1. The values of activation energies obtained from the slopes of Arrhenius plots for SDS and SDES catalyzed reaction in aqueous solutions suggest that a decrease in activation energy in presence of anionic surfactants (SDS and SDES) relative 6.26×10 8 The value of frequency factor in presence and in absence of anionic surfactants shows that the less number of collisions required in forward reaction in the presence of anionic surfactants (viz., SDS & SDES).…”

“…Micellar systems well suited for various separation and catalytic process [1][2][3] . It is reported that micelles have effects on the rate of reactions [4][5][6][7][8][9] . The kinetic model use in this study to describe the dependence of rate constant on the reaction mechanism proposed by Bruice et al, 10 and applied by Piszkiewicz 11 .…”
