Robinson Brothers routinely conducts reductive amination reactions to produce a wide range of speciality amine products and intermediates.

Reaction of an aliphatic or aromatic aldehyde, typically benzaldehyde’s, with a wide variety of alkyl amines to form an intermediate imine, which is subsequently reduced by catalytic hydrogenation to yield the amine with the product being distilled to required product specifications.

The reductive amination process offers a number of advantages over other preparative methods, amines thus produced typically having very low levels of the known process related impurities, particularly the absence of chlorides, providing both a good 'as produced' colour aspect and generally having a good shelf-life on storage under appropriate conditions.
