Provided is a selective hydrogenation process for producing aminonitriles by contacting the corresponding dinitriles with a hydrogen-containing fluid in the presence of a hydrogenation catalyst, a solvent and an additive for improving the yield of and/or selectivity to the aminonitrile.

Aminonitrile production

Provided is a selective hydrogenation process for producing aminonitriles by contacting the corresponding dinitriles with a hydrogen-containing fluid in the presence of a hydrogenation catalyst, a solvent and an additive for improving the yield of and/or selectivity to the aminonitrile. The additive comprises a carbon monoxide; a tetraalkylammonium hydroxide compound; a tetraalkylphosphonium hydroxide compound; a multi-centered metal carbonyl cluster; an organic isonitrile; a cyanide compound having at least one cyano group bound to other than a carbon atom; and afluoride compound.

Process for hydrogenating dinitriles in aminonitriles

A process for the production of 6-aminocaproamide comprising reacting 5-cyanovaleramide with hydrogen in the presence of a metal catalyst. The 6-aminocaproamide is useful, for example, in the production of caprolactam and nylon 6.

Process for preparing 6-aminocaproamide

Provided is a selective hydrogenation process for producing aminonitriles by contacting the corresponding dinitriles with a hydrogen-containing fluid in the presence of a hydrogenation catalyst, a solvent and a cyanide compound.

The present invention relates to a Raney catalyst comprising iron, cobalt, a third metal wherein the third metal is selected from the group consisting of nickel, rhodium, ruthenium, palladium, platinum, osmium, iridium and mixtures of any of the metals of this group.

Raney cobalt catalyst and a process for hydrogenating organic compounds

The present invention relates to a Raney catalyst comprising iron, cobalt, a third metal wherein the third metal is selected from the group consisting of nickel, rhodium, ruthenium, palladium, platinum, osmium, iridium and mixtures of any of these metals.

Raney iron catalyst and a process for hydrogenating organic compounds

A process for selectively hydrogenating a dinitrile to an aminonitrile is provided. The process comprises contacting a dinitrile with a hydrogen-containing fluid in the presence of a solvent comprising an alcohol or liquid ammonia, at least one metal catalyst, and a carbonyl group-containing additive such as, for example, organic amides, organic esters, salts of carboxylic acids or urea.
