Interfacial Mechanism and Kinetics of Phase-Transfer Catalysis
As the chemical reactants reside in immiscible phases, phase transfer (PT) catalysts have the ability to carry one of the reactants as a highly active species for penetrating the interface, into the other phase where the reaction takes place, and to give a high conversion and selectivity for the desired product under mild reaction conditions. This type of reaction was termed ‘‘phase-transfer ca...
متن کاملThe Gas Phase Oxidation of Acetaldehyde Reaction Mechanism and Kinetics
The mechanism of the low temperature oxidation of gaseous acetaldehyde was investigated in the temperature range of 1 50-400?°C. The minor, intermediate and major products were identified and measured quantitatively by sampling directly into the ionization chamber of an MS10-C2 mass spectrometer from the reactor. The formation of H2O, CO, CO2, HCOOH, H2, HCHO, CH3COOH and CH3OH as the major pro...
متن کاملPhase-transfer catalysis for synthesis of ethyl 2-(4-nitrophenoxy)acetate under sonication- kinetic aspects
Ultrasound assisted phase-transfer catalyzed preparation of ethyl 2-(4-nitrophenoxy)acetate from the corresponding p-nitrophenol and ethyl 2-bromoacetate using the mild solid base, anhydrous potassium carbonate, under very mild conditions is reported. The solid-liquid reactions were performed in a batch reactor equipped with reflux condenser, and ultrasonic irradiations were introduced using an...
متن کاملSynthesis of 1-(isopentyloxy)-4-nitrobenzene under ultrasound assisted liquid-liquid phase-transfer catalysis
In this paper, we report the reaction of isoamyl alcohol and 1-chloro-4-nitrobenzene was carried out in a batch reactor under aqueous-organic biphasic conditions using the techniques like phase transfer catalysis and ultrasound irradiation. Tetrabutylammonium bromide (TBAB) was employed as the phase transfer catalyst. The reaction is greatly enhanced by adding a small quantity of phase-transfer...
متن کاملInvestigation of phase - equivalent potentials by a halo transfer reaction
Using the supersymmetric quantum mechanics we investigate the wave function-sensitive properties of the supersymmetric potentials which have received a lot of attention in the literature recently. We show that a su-perdeep potential and its phase-equivalent shallow-partner potential give very similar rms values for the weakly bound systems such as the deuteron and 11 Be nuclei. Although the cor...
