OLEFIN OXIDATION METHOD, REACTION DEVICE AND SYSTEM Russian patent published in 2019 - IPC C07D301/12 C07D301/19 C07D301/04 B01J8/04 

FIELD: chemistry.

SUBSTANCE: present invention discloses an olefin oxidation method, which includes a step of successively passing a reaction feed stream under oxidation conditions C₂-C₁₆ α-olefin through layers of catalyst selected from titanium silicalites, from No. 1 to No. n, where n is integer from 2 to 50. According to the invention, if the apparent speed of each of the reaction materials passing through the catalyst beds No. 1 to No. n, respectively, is denoted by v₁ - v_n, and if m is any integer in range [2, n], then following relations are satisfied v_m-1<v_m and A_m-1/A_m>1. Present invention further discloses a reaction device with a fixed bed and an olefin oxidation system.

EFFECT: method according to the present invention is able to prolong the catalyst service life, in particular, its single service life, suppressing at the same time any side reactions for a long period of time.
