Abstract: A reactor, used for reactions between liquid/gas, or gases/liquids/solids, and has a vertical longitudinal axis with an educt feed pipe in the upper part of the reactor. Incoming gas (3) enters via an aperture in the base (5), and is distributed via a gas distributor module (9) that consists solely of straight pipes (14, 15). The gas distributor module has no curved or bent pipes. All pipes within the module are cylindrical and of circular cross section. Pipe sections are joined at right angles to each other. Horizontal distributor pipes (15) are at 40-90% of reactor chamber (4) depth.

Abstract: Preparation of an optically active 3-phenylpropionic acid derivative (I) comprises: (a) an enantioselective hydrogenation of a cis-isomer or cis/trans-isomer mixture of a phenyl compound (II) in the presence of a chiral hydrogenation catalyst to give an enantiomer enriched enantiomer mixture; (b) crystallization of the enantiomer enriched enantiomer mixture by supplementation of a basic salt former in a solvent and isolating the stereoisomer enriched solid material; and (c) optionally isolation of the protonated isomer or a substitutional cation. Preparation of an optically active 3-phenylpropionic acid derivative of formula (I) comprises: (a) an enantioselective hydrogenation of a cis-isomer or cis/trans-isomer mixture of a phenyl compound of formula (II) in the presence of a chiral hydrogenation catalyst to give an enantiomer enriched enantiomer mixture; (b) crystallization of the enantiomer enriched enantiomer mixture by supplementation of a basic salt former in a solvent and isolating the stereoisomer enriched solid material; and (c) optionally isolation of the protonated isomer or a substitutional cation.
