Latest Patents
Chesnais holds a patent for a continuous process for the hydrogenation of nitriles or nitro compounds to amines. This process involves the hydrogenation of compounds with nitrile or nitro functional groups to produce amine, aminonitrile, or aminonitro compounds. The method utilizes a heterogeneous hydrogenation catalyst in divided form and a basic compound. The reaction is conducted in a stirred reactor with an external loop for circulating the reaction mixture. This allows for the separation of hydrogenated products without withdrawing the catalyst, using tangential filtration. This innovative process is particularly useful in the hydrogenation of adiponitrile to an aminocapronitrile/hexamethylenediamine mixture. Chesnais has 1 patent to his name.
