Homogeneous Nonlinear Chemical Reactions

Uncertain dynamics in nonlinear chemical reactions

The three-variable autocatalator exhibits chaotic dynamics in an open system configuration. When the model is modified to include a dissociation reaction of the autocatalytic species, B!X+Y, followed by a recombination reaction, X+Y!C, an unusual sensitivity to initial conditions is displayed. The modified system exhibits an effectively infinite number of asymptotic attractors, some chaotic, so...

Noise-induced enhancement of chemical reactions in nonlinear flows.

Motivated by the problem of ozone production in atmospheres of urban areas, we consider chemical reactions of the general type: A+B-->2C, in idealized two-dimensional nonlinear flows that can generate Lagrangian chaos. Our aims differ from those in the existing work in that we address the role of transient chaos versus sustained chaos and, more importantly, we investigate the influence of noise...

New Homogeneous And Robust Catalyst for Heck and Suzuki Reactions

In this work, different ethyl 2,4-dioxo-4-arylbutanoate derivatives were prepared and evaluated for their Src Kinase inhibitory activity. For this purpose, the appropriate substituted acetophenone derivatives reacted with diethyl oxalate in the presence of sodium ethoxide in dried ethanol to give the corresponding products. All compounds showed moderate activities comparing with staurosporine a...

Chemical salt reactions as algebraic hyperstructures

A salt metathesis reaction is a chemical process involving the exchange of bonds between two reacting chemical species, which results in the creation of products with similar or identical bonding affiliations. Hyperstructure theory is studied from the theoretical point of view and for its applications. In this paper, we provide some examples of hyperstructures associated with salt m...
