Title:
METATHESIS PROCESS COMPRISING EXTRACTION OF ETHYLENE FORMED BY MEANS OF MEMBRANE
Document Type and Number:
Japanese Patent JP2019193932
Kind Code:
A
Abstract:
To provide a novel metathesis process using a system for removing ethylene, which simultaneously has adapted selective permeability, good temperature stability, and chemical stability with respect to the various products present in the reaction medium.SOLUTION: Provided is a process for metathesis of two α-olefinic compounds, which process is performed in a reaction device comprising two zones separated by at least one membrane: a first zone, fed with reagents and catalyst, in which the liquid-phase metathesis reaction is initiated and the liquid reaction medium is placed in circulation in contact with the wall constituted by the at least one membrane, and a second zone, fed with a stream of gas that is inert toward the at least one membrane and the constituents of the reaction medium of the first zone, optionally under a pressure slightly lower than that in the first zone or in the form of a flush with a gas stream at a sufficient flow rate, so as to bring about migration by diffusion of the ethylene dissolved in the reaction medium from the first zone to the second zone.SELECTED DRAWING: None
