    摘要: Provided is a process for safely producing, in a high yield, a high-purity polyvalent glycidyl compound from a compound having one or more 2-alkenyl ether groups and two or more 2-alkenyl groups in the molecule, by using a hydrogen peroxide aqueous solution as an oxidizing agent to oxidize the 2-alkenyl ether groups and the 2-alkenyl groups. A 2-alkenyl ether compound having, in the molecule, two or more (un)substituted 2-alkenyl groups and one or more (un)substituted 2-alkenyl ether groups is oxidized using a hydrogen peroxide aqueous solution as an oxidizing agent in the presence of a tungsten compound and a quaternary ammonium salt as catalysts and of phosphoric acid as a co-catalyst, while controlling the pH of the reaction solution to 1.0-4.0 using an acid other than phosphoric acid. During the oxidation, the step of adding the hydrogen peroxide aqueous solution to the reaction solution and the step of adding the acid other than phosphoric acid thereto are alternately repeated at intervals two or more times.

    摘要: This invention discloses an olefin oxidation process, including a step of under olefin oxidation conditions, successively passing a reaction feed from the No.1 catalyst bed through the No.n catalyst bed, wherein if the apparent velocity of each of the reaction materials passing from the No.1 catalyst bed through the No.n catalyst bed is respectively named as v 1 to v n , and if m represents any integer in the region [2, n], the relationship v m-1 m holds. The process according to this invention is capable of extending the service life of the catalyst, especially the single-pass service life thereof, and at the same time, suppressing any side-reaction over a prolonged period of time. This invention further discloses a fixed-bed reaction apparatus and a system for olefin oxidation.
