MUMBAI, India, June 19 -- Intellectual Property India has published a patent application (202647066608 A) filed by China Petroleum & Chemical Corporation; and Sinopec Research Institute Of Petroleum Processing on May 27, 2026, for N-Alkylation Catalyst, Preparation Method Therefor And Use Thereof.
Inventors include Zhou, Shunli; Li, Yongxiang; Zhang, Chengxi; Fu, Qiang; Xing, Enhui; and Shu, Xingtian.
The application for the patent was published on June 05, 2026, under issue no. 23/2026.
Abstract: The present invention relates to an N-alkylation catalyst, a preparation method therefor and a use thereof. The catalyst comprises a molecular sieve, an oxide binder and a modification component, the modification component being loaded on the molecular sieve and the oxide binder, the modification component comprising Cu and P, and the medium-strong acid content of the catalyst accounting for 35% or more of the total acid content. By means of controlling the order of addition of raw materials in a catalyst preparation process, and selecting Cu and P for synergistic modification, an N-alkylation catalyst having high activity, high stability, extended service life, and good recycling performance can be obtained. The catalyst is used to produce N,N-dimethylaniline, and can reduce side reactions, enable an N-alkylation reaction to operate stably for a long period, and expand a workable reaction temperature range, facilitating continuous industrial production.
