Process for preparing bisphenol A |
| abstract |
The present invention provides a process for preparing bisphenol A with a high conversion and selectivity by reacting phenol with acetone in the presence of both a polyorganosiloxane having a mercapto group-containing hydrocarbon group and an acid. It is preferable that the polyorganosiloxane having a mercapto group-containing hydrocarbon group and the acid is a polyorganosiloxane having both a mercapto group-containing hydrocarbon group and a sulfonic acid group. |
