Benzylamine can be produced by several methods, the main industrial route being the reaction of benzyl chloride and ammonia. It is also produced by the reduction of benzonitrile and reductive amination of benzaldehyde over Raney nickel. It was produced accidentally by Rudolf Leuckart in the reaction of benzaldehyde with formamide in a process now known as the Leuckart reaction, a general process in which reductive amination of aldehydes or ketones yields the corresponding amine
Butyraldehyde, also known as butanal, is an organic compound with the formula CH3(CH2)2CHO. This compound is the aldehyde derivative of butane. It is a colourless flammable liquid with an acrid smell. It is miscible with most organic solvents. Traditionally, hydroformylation was catalyzed by cobalt carbonyl and later rhodium complexes of triphenylphosphine. The dominant technology involves the use of rhodium catalysts derived from the water-soluble ligand Tppts. An aqueous solution of the rhodium catalyst converts the propylene to the aldehyde, which forms a lighter immiscible phase. About 6 billion kilograms are produced annually by hydroformylation. A significant application is its conversion to 2-ethylhexanol for production of plasticizers.
