Process for the preparation of fumaric acid monoesters |
| 摘要 |
Fumaric acid monoesters can be prepared by introducing a hydroxyl compound at a rate corresponding to the progress of the reaction into a solution or a melt of maleic anhydride, which may optionally be substituted, if appropriate in the presence of a cis-trans catalyst. New fumaric acid monoesters can be formed by the process.
