Method for producing bis(4-hydroxyaryl)alkanes |
| abstract |
The present invention relates to a method for producing Bis (4-hydroxy-aryl)alkanes by means of acid catalysed conversion of aromatic hydroxy compounds with ketones. The temperature, ketone and water content of a liquid reaction mixture is adjusted by means of a gas phase with a suitable composition. |
