Researchers develop catalyst to improve synthesis of amines
Researchers at the Tokyo Institute of Technology have made a major breakthrough in the large scale production of biofuels and bio-oils, according to a study in the Journal of the American Chemical Society. The researchers used a ruthenium-based catalyst to improve the synthesis of primary amines. The team found the ruthenium-based catalyst produced a yield of 93% from a glucose biomass, with virtually no by-products observed.

Researchers at Tokyo Institute of Technology have developed a new catalyst to improve the synthesis of primary amines (derivatives of ammonia).

It is claimed that in the future the newly developed ruthenium based catalyst could also impact the development of biofuels and bio-oils.

Primary amines are industrially important compounds which are used in the preparation of a wide range of dyes, detergents and medicines. Many attempts have been made to use platinum, nickel or palladium catalysts to improve the synthesis of amines, but few have been successful in reducing the formation of tertiary amines and other undesired by-products.

In a study published in the Journal of the American Chemical Society, the team from Tokyo describe how they’ve developed a ‘highly selective’ catalyst consisting of ruthenium nanoparticles supported on niobium pentoxide (Ru/Nb 2 O 5 ). The team have demonstrated that the catalyst is capable of producing primary amines from carbonyl compounds with ammonia (NH 3 ) and dihydrogen (H 2 ), with negligible formation of by-products.

After discovering the ruthenium based catalyst consistently produces yields of over 90% when converting furfural to furfurylamine in a process known as reductive amination1, Michikazu Hara of Tokyo Tech's Laboratory for Materials and Structures and his team explored how effectively the catalyst could break down biomass in the form of glucose into 2,5-bis(aminomethyl)furan, a monomer for aramid production.
