Latest Patents

One of Seyfert's latest patents is a process for preparing methylenedianiline and methylenebis(phenylisocyanate). This innovative process involves reacting aniline with formaldehyde in the presence of acid catalysts. The method employs a semicontinuous process where aniline, with or without an acid catalyst, is introduced, and formaldehyde is fed through a mixing element into a circuit. This circuit allows for the circulation of aniline and formaldehyde, and after feeding in at least 50% of the total amount of formaldehyde, the reaction mixture is heated to a temperature above 75°C. Additionally, the invention relates to a process for preparing polyisocyanates by phosgenation of amines obtained through this method.
