MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202611001258 A) filed by Maharishi Markandeshwar, Ambala, Haryana, on Jan. 6, for 'indole-based supported catalysts for the selective phenol oxidation.'
Inventor(s) include Dr. Praveen Kumar Gupta; Savita Kumari; and Dr. Ravindra K. Rawal.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "The invention relates to indole-based supported catalysts for selective oxidation of phenols and provides a method for preparing metal-loaded polymer-supported catalytic materials. The method includes synthesizing a Schiff-base ligand, 2-((1H-indole-3-yl)methyleneamino)phenol (HIMAP), by condensation of indole-3-carboxaldehyde and 2-aminophenol in ethanol under reflux with piperazine, immobilizing the ligand onto chloromethylated polystyrene in DMF in the presence of triethylamine to yield PS-HIMAP, and coordinating metal ions by reacting the functionalized polymer with methanolic solutions of V, Cu, Mn, Ni, or Fe salts under reflux. The process yields stable metal-loaded catalysts suitable for selective oxidation applications."
