Abstract: The present invention relates to a process for the dehydration of organic compounds to give unsaturated compounds.

Abstract: In a device for the temperature control of microcomponents, in particular micro-reactors, which preferably have a plate-shaped design and preferably consist of silicon, at least one microcomponent is pressed against a temperature-control element in a holder. A flat heat-conducting connection exists between the microcomponent and the temperature-control element.

Abstract: A device for the emulsification and separation of small amounts of immiscible liquid phases has essentially a cover plate (2), which can be tightly connected to a base plate (1), where microchannels (4,4a,5,6,6a) in the form of grooves are cut out on the inner surface (3,3a) of the base plate (1) and/or cover plate (2). In a mixing zone, two microchannels (4,4a) run in a wave shape crossing one another a number of times. In a subsequent separation zone, they run essentially straight combined in a common microchannel (5). The otherwise tightly sealed-off microchannels (4,4a,5,6,6a) can be filled and emptied again via inlet apertures (8,8a) and outlet apertures (9,9a).

Abstract: A connection coupling forms a line connection for liquid or gaseous substances to microcomponents (1) in platelet form. A coupling body (2), which is substantially U-shaped in cross section, accommodates the edge of the plate-like microcomponent (1) between an upper limb plate (3), which has the line connection (14), and a lower limb plate (5). An edge web (6) forms a transverse stop for an edge (8) of the microcomponent (1). A further stop means, for example a lug (9), forms a longitudinal stop for positioning of the microcomponents (1).

Abstract: The present invention relates to a process for the preparation of indoles.

Abstract: The present invention relates to a process for the metathesis reaction of unsaturated organic compounds.

Abstract: The invention relates to a method for oximating organic carbonyl compounds and/or CH-acid compounds, wherein at least one organic carbonyl compound and/or CH-acid compound in a liquid or dissolved form is mixed with at least one oximating agent in a liquid or dissolved form in at least one microreactor, is reacted during a residence time and the organic oxime thus formed is optionally isolated from the reaction mixture.

Abstract: The invention relates to a method for the 1,3 dipolar cycloaddition of organic compounds, characterised in that the reaction is carried out in a microreactor.

Abstract: The present invention relates to a process for the formylation of organic compounds.

Abstract: The present invention relates to a process for the oxidation of tertiary amines and nitrogen-containing aromatic heterocycles to amine oxides.

Abstract: The present invention relates to a process for the epoxidation of olefins.

Abstract: The present invention relates to a process for the Baeyer-Villiger oxidation of organic carbonyl compounds.

Abstract: A coupling for microcomponents has several essentially plane-parallel plates with line connections for delivering and discharging liquid or gaseous components. The line connections are mounted on a connection block which protrudes through openings in the plates with fixing segments that engage a pressure plate retained by a clip. The line connections open out in an area of line bores in the plate.

Abstract: A device for mixing very small quantities of liquids comprises at least one mixing element with at least one inlet channel and at least one outlet channel; at least two microchannels issue from the inlet channel, all such issuing channels lying in a single branching plane. The microchannels are led to a confluence element in a plane which is rotated 90 degrees in relation to the branching plane. The mixer element is arranged in the planar surface of a substrate, the planar surface being hermetically sealed by a covering. The invention concerns a device for mixing liquids in which mixing is effected by the flow of the liquids to be mixed through narrow channels.

Abstract: A device for deflecting light beams, in particular laser beams, has mirror surfaces which are arranged at a drivable rotating body. The rotating body is formed of monocrystalline material and the mirror surfaces are formed by the crystal planes and are arranged symmetrically with respect to rotation.
