Title
(EN) OLEFIN METATHESIS REACTIONS IN CARBON DIOXIDE MEDIUM
(FR) REACTIONS DE METATHESE D'OLEFINES DANS UN MILIEU CONTENANT DU DIOXYDE DE CARBONE
Abstract
(EN)
The present invention provides a process for olefin metathesis. The process comprises (a) providing a reaction mixture comprising an olefin, a metathesis initiator, and a reaction medium comprising carbon dioxide, and (b) reacting the reaction mxiture to provide a metathesis modified olefin. The olefin metathesis reaction may be an olefin metathesis exchange reaction, an olefin metathesis degradation reaction, or a metathesis polymerization reaction. The carbon dioxide medium may be liquid, supercritical, and gaseous carbon dioxide.
(FR)
Un procédé, qui permet la métathèse des oléfines, consiste (a) à disposer d'un mélange de réaction comprenant une oléfine, un initiateur de métathèse et un milieu de réaction contenant du dioxyde de carbone, et (b) à faire réagir ce milieu de réaction pour obtenir une oléfine modifiée par métathèse. La métathèse des oléfines peut intervenir par une réaction d'échange, de dégradation ou de polymérisation. Le milieu contenant du dioxyde de carbone peut le faire sous forme liquide, supercritique ou gazeuse.
