Abstract: A process for producing bisphenol A which comprises reacting phenol with acetone. The reaction is conducted at a higher temperature while maintaining high selectivity to thereby attain high productivity. Also provided are: a cation-exchange resin characterized by comprising a syndiotactic polystyrene polymer and cation-exchange groups incorporated therein and by having an acid amount of 0.8 meq/g or larger; and a catalyst comprising the cation-exchange resin. The process for bisphenol A production employs the cation-exchange resin catalyst.
