A process for hydrogenating a sample in a pressure range below supercritical pressure values includes supplying at least a solvent of the sample to be hydrogenated by a feed pump with a constant volume rate into a flow path to create a base solution; adding the sample being dissolved into the flow path; feeding hydrogen into the flow path through a valve configured to transmit hydrogen only into a single direction; leading the dissolved sample in the presence of a catalyst through a hydrogenation reactor, where the reactor is inserted into a section of the flow path located after the hydrogen feeding position; maintaining the pressure of the reaction in a given pressure range by element of a pressure-adjusting unit, and collecting a hydrogenate formed within the hydrogenation reactor in a product receptacle connected to the end of the flow path.

Laboratory scale continuous flow hydrogenation process

A laboratory scale continuous flow hydrogenation apparatus () includes a reservoir (), a feed pump (), a mixing element () with two inlets and an outlet, a hydrogenation reactor () and a pressure-adjusting unit (), all connected into a flow path. A hydrogen source () and a one-way valve () are arranged between the hydrogen source () and the second inlet of the mixing element (). The feed pump () can provide a constant volume rate. The reservoir () contains at least a solvent base solution of the sample to be hydrogenated. The hydrogenation reactor () connects into the flow path by detachable connections and is formed as a replaceable cartridge containing a packing which increases the flow resistance and facilitates mixing. The pressure-adjusting unit () connects into the flow path after the hydrogenation reactor () and is provided with a regulation controlled electrically.
