| titleOfInvention | Improved Process for Coupling Coupled 4,6-Dibenzoylorsorcinol |
| abstract | The present invention relates to a process for the production of methylene-crosslinked 4,6-dibenzoylesorcinol dimers in high yield in a single step. This method heats 4,6-dibenzoylesorcinol (DBR) with para-aldehydes or aromatic aldehydes in a carboxylic acid solvent in the presence of a strong acid catalyst. |
