- generally known materials and techniques come into consideration.
- a coating it is in particular possible to adjust the surface properties of the microsieve.
- a wettable or non-wettable coating can be applied in relation to the respective liquid phase to be separated.
- the device When the device is used to contact a liquid having a high surface tension (e.g., water) with a gas, it is particularly advantageous to set the surface of the screen to be water repellent (hydrophobic: water's interface angle to the screen surface »90 °).
- a low surface tension liquid e.g., toluene
- Suitable coating agents for the coating of the microsieve are, for example, silane-based or polytetrafluoroethylene (Teflon) coating compositions.
- a particularly preferred coating agent using aqueous liquid phases is polytetrafluoroethylene (Teflon).
- microsieve In addition to adjusting the wettability by the process media, it may also be advantageous to coat the microsieve with a catalytically active substance. - -
- process channel in the direction perpendicular to the screen surface has a small extent (depth).
- process channel depths of 5 to 50 .mu.m, particularly preferably 10 to 30 .mu.m are to be used at least on the side of the liquid process medium.
- the introduction of the process channels with the o.g. Channel depths into the channel plates can be defined with sufficient precision by microfabrication methods known from micro process engineering such as e.g. by etching, machining or laser material processing (ablation).
- the channel plates on the side of the liquid process channels can be made flat and the process channels are defined by introducing a structured in the form of through holes film between the channel plate and microsieve. The thickness of the film in this case corresponds to the process channel depth.
- connection or distribution channels are preferably to be designed such that a homogeneous distribution of the fluid streams is ensured in the process channels.
- the immiscible fluids flow in the process channels separated by the microsieve in substantially parallel directions. It is particularly advantageous if the two fluids flow in the process channels separated by the microsieve in opposite directions.
- the device may be advantageous to equip them with means for introducing or for discharging heat.
- means for introducing or for discharging heat for example, further, separate from the process and connection / distribution channels channels are introduced into the channel plates, which the flow through the channel plates with a Allow temperature control, or it can be installed in the device additional, provided exclusively with Temperierkanälen channel plates.
- a heating by electrically operated resistance heating elements, by microwave irradiation or irradiation of other electromagnetic waves or cooling using Peltier elements is possible.

- the device according to the invention can be used both in absorption and in distillation processes.
- the device can be used advantageously for carrying out chemical reactions between immiscible fluids, in particular between gases and liquids. Due to the small depth of the process channels, it is possible to dissipate the reaction heat generated at the interface between the two reaction media very quickly and efficiently. This makes it possible, for example, highly exothermic gas-liquid reactions, such. direct halogenation, phosgenation or ozonization of organic media at high concentrations of the reaction media and in a very short time under controlled temperature and residence time conditions. Furthermore, chemical reactions between the reaction media or individual components thereof can be accelerated or even made possible by catalytically active substances applied to the microsieve or to the inner surfaces of one of the process channels.
- the device according to the invention makes it possible to process a significantly higher mass flow with a comparably high mass transfer capacity, such as known microstructured devices for separating fluid media or for carrying out chemical reactions between immiscible fluid media relative to the surface of the release agent (microsieve), which allows less or get through smaller devices.

- MFSC microfabricated stripping column
- Test data were applied with screen holes of diameter 1.2 ⁇ m and 0.45 ⁇ m.
- the active screen has a thickness of 0.8 ⁇ m, i. for the sieve with a hole diameter of 1.2 ⁇ m, the aspect ratio is about 0.7 (not according to the invention) and for the sieve with a hole diameter of 0.45 ⁇ m the aspect ratio is 1.8 (according to the invention). It has surprisingly been found that, with an aspect ratio of 1.8, significantly higher throughputs could be realized than with the sieve with the lower aspect ratio of the openings.
