MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202617060219 A) filed by Nissan Chemical Corporation on May 12, 2026, for Method For Producing Aromatic Amino Compound.
Inventor includes Nagao Masato.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: Provided is a new method for producing an aromatic amino compound that is useful as a production intermediate for electronic materials and pharmaceutical and agricultural chemicals, and that has, at a moiety other than an aromatic ring, at least one multiple bond selected from carbon-carbon, carbon-nitrogen, and carbon- oxygen. This method for producing an aromatic amino compound is characterized by catalytically reducing an aromatic nitro compound having, at a moiety other than an aromatic ring, at least one multiple bond selected from carbon-carbon, carbon-nitrogen, and carbon-oxygen, by using a Pt/C catalyst in the presence of at least one phosphorus compound (A) selected from the group consisting of phosphorus compounds represented by formula (1), phosphorus compounds represented by formula (2), and phosphorus compounds represented by formula (3). (1): P(R1)3 (2): PO(R2)3 (3): (R3)2P-R4-P(R3)2 (The meaning of each symbol in formulae (1)-(3) is as defined in the description.)
