Abstract: Disclosed is a method for producing at least one chemical reaction product by chemically reacting one or several reactants that is/are optionally dissolved in one or several solvents and is/are supplied as a feed stream by bringing the same in contact with a heterogeneous catalyst in a continuously operated fixed-bed reactor which is filled with a particle bed, a continuous annular chromatograph (CAC) that is filled with the particle bed being used as a fixed-bed reaction in which the at least one reaction product is formed and purified while the at least one purified reaction product as well as optionally provided secondary products and/or non-reacted reactants are withdrawn at a different, predetermined azimuthal position of the annular chromatograph, respectively. The inventive method is characterized in that only one type of particle material is used in a single particle bed as both a formation catalyst and a chromatographic medium for purifying the at least one reaction product in the particle bed.

Abstract: A continuous annular chromatography (CAC) device is disclosed including a stationary column head, a stationary eluate ring, a rotating body which is located between said column head and said collecting ring and which can rotate about a vertical axis and contains a chromatographic separating medium and a drive device. An extension can be coupled to a drive shaft of the drive device with a rapidly detachable connection.

Abstract: The invention relates to a CAC device comprising a stationary column head, a stationary eluate collecting ring, a rotating body which is located between said column head and said collecting ring and which can rotate about a vertical axis and contains a chromatographic separating medium; and a drive device. Said rotating body (1) is connected to a rotating platform (4) at its bottom end. This rotating platform (4) is slidingly, sealingly guided on the eluate collecting ring (5) and has an extension on the underside. The extension can be coupled to a drive shaft (2) of the drive device (8) with a rapidly detachable connection and the stationary column head the rotating body (1) with the rotating platform (4) and the attached eluate collecting ring (5) can be connected to form a CAC module and can be removed from the drive shaft (2) as a unit. The invention also relates to an inverse CAC method using the inventive device.
