Apparatus for manufacturing fluid reaction products

A reactor for production of a fluid reaction product, comprising:

• a reaction chamber;
• a plurality of fluid connections to supply fluid reactants to the reaction chamber;
• a reception chamber located directly below the reaction chamber;
• a transfer device providing a fluid connection between the reaction chamber and the reception chamber so that the reception chamber receives a fluid reaction product produced in the reaction chamber wherein the transfer device includes an inner tube and an outer tube arranged co-axially around the inner tube so that both tubes are arranged essentially perpendicularly to a floor of the reaction chamber, the inner tube passing through the reaction chamber floor and opening into the reception chamber, there being a first gap with a gap width between the inner and outer tubes, which width is suitable to allow the fluid reaction product to rise in the gap as a result of lifting forces, and the outer tube having an upper end and a closure included at the upper end;
• a control unit;
• and
• a first device, arranged in the reaction chamber to be in direct contact with the supplied fluids to determine a filling level, the first device comprising at least one switching point which is operatively coupled with the control unit such that the supply of the fluid reactants into the reaction chamber is controlled and carried out sequentially.
