Latest Patents
Stuhler's latest patents focus on innovative processes for the preparation of saturated primary fatty amines. One of his notable inventions involves the hydrogenation of unsaturated primary fatty amines. This process is achieved by reacting the unsaturated primary fatty amine with hydrogen at temperatures ranging from 80 to 160 degrees Celsius and pressures between 1 to 40 bar. The presence of a nickel or cobalt catalyst is essential for this reaction. Additionally, if the fatty amine contains ammonia, it is substantially removed before the hydrogenation process. Another patent details a method for hydrogenating unsaturated fatty acid nitriles in the liquid phase, also utilizing nickel or cobalt catalysts. This two-step process results in the conversion of nitrile groups to primary amino groups, followed by the hydrogenation of double bonds to yield saturated fatty amines with a very low iodine number.
