Latest Patents

Nitsche holds a patent for a process titled "Process for the preparation of 4-hydroxy-1,2,2,6,6-pentamethylpiperidine." This innovative method describes the preparation of 4-hydroxy-1,2,2,6,6-pentamethylpiperidine (HPMP) from 4-oxo-2,2,6,6-tetramethylpiperidine (TAA). The process involves reducing TAA to 4-hydroxy-2,2,6,6-tetramethylpiperidine (HTMP) through catalytic hydrogenation in water. The resulting crude solution can be concentrated by distillation and then reacted with formaldehyde or paraformaldehyde in at least a 20% molar excess, along with formic acid. The crude product melt is subsequently separated from the reaction mixture and purified by distillation. Nitsche's patent is a testament to his innovative approach, and he has 1 patent to his name.
