Latest Patents

Tomoyuki Ueno holds a patent for a preparation process of indoles. This process involves reacting an aniline with a diol, where a catalyst, whose activity has been reduced through its use in the reaction, is brought into contact with an inert gas containing 5 vol. % or less of oxygen. This method allows for the regeneration of the catalyst for repeated utilization. Furthermore, the activity of the regenerated catalyst is enhanced when subjected to a reducing treatment for activation upon reutilization.
