Method for producing a bisphenol |
| abstract |
In one embodiment, a method for preparing a bisphenol compound, comprising reacting a phenolic compound with a reactant comprising one or both of an aldehyde and a ketone in the presence of a catalyst system and methanol to produce the bisphenol compound, The methanol being present in an amount of 250 to 5,000 ppm based on the total weight of the reactants; The catalyst system comprises an ion exchange resin comprising a plurality of sulfonic acid sites; And from 5 to 35 mole percent of the adducted promoter molecules based on the total number of moles of sulfonic acid points in the catalyst system; And a method for preparing a bisphenol compound wherein the adherent promoter molecule comprises at least two thiol groups per attached co-catalyst molecule. |
