Reaction effects in flows - Open Access .click

Polymer Engineering & Science, 2002
AbstractThe esterification of the maleic anhydride residue (MA) in a hydrogenated styrene‐butadiene‐styrene block copolymer (SEBS‐g‐MA) with a polycaprolactone diol (PCL) was carried out in a melt. Experiments in static melts found that the reaction had an induction period followed by a rapid consumption of the reactants.

Effective dimensions and chemical reactions in fluid flows

Physical Review E, 2007
We show that chemical activity in hydrodynamical flows can be understood as the outcome of three basic effects: the stirring protocol of the flow, the local properties of the reaction, and the global folding dynamics which also depends on the geometry of the container.

Flow effects in the polymer cyclization reaction

Macromolecular Theory and Simulations, 1997
AbstractWe investigate the effect of shear and uniaxial extensional flows on the rate of the cyclization reaction in polymers. We find that for such an intramolecular diffusion‐controlled reaction the flow always reduces the reaction rate, in contrast to the previously studied case of intermolecular reactions, where linear flows enhance the reaction ...

Micromixing effects on a parallel reaction in flow reactors

Chemical Engineering & Technology, 1993
AbstractUsing the micromixing concepts of Danckwerts and Zwietering, the Peclet number Pe has been correlated mathematically to the degree of segregation J for the axial dispersion model. The results were applied to compare the micromixing effects on a model, mixed‐order parallel reaction system in continuous flow reactors.
