AN IMPROVED PROCESS FOR THE SYNTHESIS OF DIMETHYL FUMARATE
The present invention describes an improved process for the industrial scale production of dimethyl fumarate. The process involves a one-pot ring opening reaction of maleic anhydride to monomethyl maleate and isomerization into the corresponding monomethyl fumarate in presence of a Lewis acid. Final...

Zusammenfassung: | The present invention describes an improved process for the industrial scale production of dimethyl fumarate. The process involves a one-pot ring opening reaction of maleic anhydride to monomethyl maleate and isomerization into the corresponding monomethyl fumarate in presence of a Lewis acid. Finally the mono methyl fumarate was converted into the dimethyl fumarate by an acid catalyzed esterification reaction. |
