The expert panel for the appraisal was headed by Professor Li Guixian from Lanzhou University of Technology, with Professor Yang Shangdong and Professor Dong Zhengping from Lanzhou University, Professor Chen Lihua from Northwest Minzu University, and Professor Wang Qizhao from Northwest Normal University as members. After reviewing the documents, listening to the presentations, and conducting inquiries and discussions, the expert group unanimously agreed that this technology passed the evaluation. The development of a complete set of industrial production technologies for 30,000 tons per year of new N-methylaniline is considered an important achievement in China’s fine chemicals sector. This technology features a simple process flow and mild reaction conditions; the catalyst exhibits excellent selectivity and longevity, offering good prospects for application, and it is particularly significant for the integrated development of petrochemical and coal chemical industries. The complete set of technologies has reached an internationally advanced level; it is recommended to accelerate their dissemination. Through processes such as innovation in basic research, scale-up production of catalysts, pilot-scale studies at a thousand-ton level, and the development of process packages, a total of **20 patents have been applied for, 15 of which have been granted. 30 SCI papers have been published, and a process package with an annual capacity of 30,000 tons has been developed. The conditions for constructing industrial facilities and promoting related technologies are already in place. N-Methylaniline is an important fine chemical that is widely used as an intermediate in pesticides, dyes, pharmaceuticals, and organic synthesis. It can also be used as an anti-knock agent for gasoline, an acid absorber, a solvent, and a stabilizer for explosives. The current mainstream industrial production technologies for N-methylaniline still suffer from problems such as high levels of waste, low yields, and short catalyst replacement cycles. The \"30,000 tons per year new type of industrial production technology for N-methylaniline\" developed by the Lanzhou Institute of Chemical Physics provides technical support for China’s related chemical industries to move towards higher-end levels and to undergo adjustments and upgrades aimed at improving quality and efficiency.
