Enhanced Selectivity in the Hydrogenation of Anilines to Cyclo-aliphatic Primary Amines over Lithium-Modified Ru/CNT Catalysts

The hydrogenation of aromatic amines to the corresponding cycloaliphatic primary amines is an important industrial reaction. However, secondary amine formation and other side reactions are frequently observed, resulting in reduced selectivity. The side products are formed mostly on the support, yet support effects are little understood at present. This study describes the facile modification of Ru/CNT catalysts with LiOH, by this means significantly improving catalyst selectivity in toluidine hydrogenation without decreasing the activity of the catalysts. The effect is explained by LiOH diminishing acidic sites on the catalyst support and enhancing the adsorption of the aromatic ring on the metallic ruthenium nanoparticles. With the LiOH-modified Ru/CNT catalyst, other substrates, such as methylnitrobenzenes, are also converted efficiently. This study thus describes an improved catalyst for the preparation of cyclohexylamines and provides guidelines for future catalyst design.

METHOD OF CONVEYING LIQUIDS

The present invention relates to a method of continuously conveying a liquid which is used as starting material in a chemical reaction by means of a displacement pump having physically separate forward-transport valves and a liquid-filled bidirectional flow line between displacement pump and forward-transport valves, wherein an auxiliary liquid which is a product or a starting material of the chemical reaction and has a melting point which is below the melting point or below the saturation temperature of the liquid to be conveyed is present in the bidirectional flow line. The present invention additionally provides for the use of a product formed by hydrogenation of an aromatic compound as auxiliary liquid for conveying an aromatic compound and also the use of an alcohol or an ester derived from alcohol and carboxylic acid as auxiliary liquid for conveying carboxylic acids or carboxylic acid derivatives.
