摘要: Secondary alkyl amine derivatives of ethylenediamine are formed in a one-step reaction when ethylenediamine is substantially simultaneously continuously mixed with a methyl alkyl ketone to form a reaction mixture which is continuously hydrogenated in the presence of a hydrogenation catalyst and hydrogen, the alkyl group containing 1 to 4 carbon atoms.

摘要: Amines are produced by reacting at elevated temperature a first reactant which is either an alcohol, an aldehyde or a ketone with a second reactant which is either ammonia, a primary or secondary amine or a nitrile in the presence as catalyst of a composition comprising (i) nickel, (ii) ruthenium, and (iii) at least one other transition metal selected from either the second or third row transition metals, for example palladium, rhenium or iridium.

摘要: Metal-organic framework (MOFs) compositions based on post¬synthetic metalation of secondary building unit (SBU) terminal or bridging OH or OH2 groups with metal precursors or other post-synthetic manipulations are described. The MOFs provide a versatile family of recyclable and reusable single-site solid catalysts for catalyzing a variety of asymmetric organic transformations, including the regioselective boryiation and siiylation of benzyiic C—H bonds, the hydrogenation of aikenes, imines, carbonyls, nitroarenes, and heterocycles, hydroboration, hydrophosphination, and cyclization reactions. The solid catalysts can also be integrated into a flow reactor or a supercritical fluid reactor.

摘要: Catalysts, in particular clay catalysts, use in alkylation reaction of aromatic compounds, e.g., aromatic amines, that have lost activity during use, are regenerated by contacting the used catalyst with a mixture of a minor amount of an acid, in a mixture with water and an organic solvent. The regeneration process is readily incorporated into an alkylation process for aromatic amines.

摘要: Method for pretreating the copper-based catalyst having the steps of dehydrating the copper-based catalyst at an elevated temperature, reducing the dehydrated copper-based catalyst with hydrogen, and passivating the activated copper-based catalyst to obtain a catalyst suitable for N-alkylation. The dehydration and reduction steps may be conducted simultaneously.
