In the reaction process, at least two educts A, B are divided by a system, assigned to each of them, of slit-like microchannels,into spatially separate fluid lamellae, which then emerge into a common mixing and reaction space,. The fluid lamellae here have a thickness <1,000 &mgr;m, preferably <100 &mgr;m, at a width thickness ratio of at least 10. It is essential here that educts A, B can emerge as thin fluid lamellae,into the mixing/reaction space,, each fluid lamella,of an educt A being led into the mixing/reaction space,in the immediate vicinity of a fluid lamella,of another educt B. The adjacent fluid lamellae,then subsequently mix by diffusion and/or turbulence. As a result, the mixing operation is accelerated substantially compared with conventional reactors. In the case of rapid chemical reactions, the formation of undesirable by-products or secondary products is largely prevented in this manner.

Process for carrying out chemical reactions using a microlaminar mixer

A microstructures lamellae mixer comprising a guide component for supplying fluids to be mixed to a mixing chamber, the guide component being composed of a plurality of foils which are layered one above the other and into which microchannels are incorporated such that separate fluids supplied to the guide component are formed into spatially separated microstreams which then emerge adjacent to each other in a mixing chamber.

Device for carrying out chemical reactions using a microlaminar mixer

A method and a device for gentle continuous mixing of a droplet dispersion with a liquid are described, wherein the liquid is injected into the droplet dispersion in the form of a plurality of fine liquid jets, such that the kinetic energy of the liquid jets is dissipated at a short distance from the injection point and further mixing is effected by circulating flow generated in the vessel and exhibiting shear rates of less than 20/s.
