Claims
- 1. A process for the continuous production of bisphenol-A comprising continuously reacting phenol with acetone using an acid catalyst resin to form BPA and water and continuously removing said water from said reaction.
- 2. A process as set forth in claim 1 wherein said acid catalyst resin is provided in a carousel simulated moving bed reactor.
- 3. A process as set forth in claim 1 wherein said acid catalyst resin is an ion exchange resin.
- 4. A process as set forth in claim 1 further including the step of introducing an eluent into an elution zone of said reaction.
- 5. A process as set forth in claim 4 wherein said eluent is phenol.
- 6. A process as set forth in claim 2 where the mole ratio of phenol to acetone is in the range of about 6:1-20:1.
- 7. A process as set forth in claim 2 where the process temperature is in the range about 50-100° C.
- 8. A process as set forth in claim 2 wherein the beds in said reactor are connected in series to have a unidirectional fluid flow.
- 9. A process as set forth in claim 2 wherein at least one bed in said reactor is configured to have a reverse flow or to provide a fluid flow direction opposite to said media flow or toward the top of the column, or both.
