MUMBAI, India, Oct. 5 -- Intellectual Property India has published a patent application (202637101545 A) filed by China Petroleum & Chemical Corporation; and Sinopec Dalian Research Institute Of Petroleum And on August 22, 2026, for Sn-Y Type Molecular Sieve, Preparation Method Therefor And Use Thereof, And Oxidation Reaction Method For Cyclic Ketone.
Inventors include Xue, Jinghang; Qin, Bo; Liu, Wei; Zhang, Tong; and Zhang, Xiaoping.
The application for the patent was published on October 02, 2026, under issue no. 40/2026.
Abstract: An Sn-Y type molecular sieve, a preparation method therefor and the use thereof, and an oxidation reaction method for a cyclic ketone. The surface silicon/tin molar ratio of the molecular sieve is 50-70, and the bulk silicon/tin molar ratio is 200-300; with respect to the Sn-Y type molecular sieve, Sn is mainly intensively distributed on the outer surface of a Y molecular sieve, thus achieving better catalytic performance for the Baeyer-Villiger oxidation reaction of a cyclic ketone.
