PROCESS FOR THE SYNTHESIS OF 9,9-BIS(HYDROXYMETHYL)FLUORENE
The present invention relates to a novel process for the synthesis of 9,9-bis(hydroxymethyl)fluorene. The syntheses from fluorene to 9,9-bis(hydroxy-methyl)fluorene via a hydroxymethylation and further to 9,9-bis(methoxymethyl)-fluorene via a etherification are known. 9,9-bis(methoxymethyl)fluorene...

| Zusammenfassung: | The present invention relates to a novel process for the synthesis of 9,9-bis(hydroxymethyl)fluorene. The syntheses from fluorene to 9,9-bis(hydroxy-methyl)fluorene via a hydroxymethylation and further to 9,9-bis(methoxymethyl)-fluorene via a etherification are known. 9,9-bis(methoxymethyl)fluorene is a compound that is used as an electron donor for Ziegler-Natta catalysts. The present invention is related to an improvement in the synthesis of 9,9-bis(hydroxymethyl)fluorene leading to a decrease in the amount of solvent used and an easier work up while achieving high yield and purity. |
