Latest Patents
Bernard Darrier holds a patent for a hemihydrogenation method for dinitriles. This invention focuses on the hydrogenation in amine function of a nitrile function of a dinitrile to obtain the corresponding aminonitrile. Specifically, the method involves the hemihydrogenation of a dinitrile into the corresponding aminonitrile in a liquid medium. The process is characterized by the use of a Raney nickel or cobalt catalyst containing copper and/or silver and/or gold, along with an alkaline or alkaline-earth metal hydroxide. This innovative approach allows for the hemihydrogenation of adiponitrile, resulting in amino-6 capronitrile, which can be easily transformed into caprolactam, a key starting product for the synthesis of polyamide-6.
