Abstract
A nitrile-containing mixture, which includes a nitrile dissolved in a higher alcohol solvent, and hydrogen are fed to a reactor containing a catalyst. An amine is produced by hydrogenating the nitrile that is dissolved in the higher alcohol solvent. In a preferred embodiment, the reactor also contains a caustic solution. The preferred nitrile-containing mixture includes octadecaneditrile (ODDN) and hexanol to produce a preferred octadecanediamine (ODDA) through hydrogenation.
