A process for preparing a fixed bed of an acidic cation exchange resin for producing bisphenols in which the acidic cation exchange resin is uniformly and intermediately neutralized with a sulfur compound having nitrogen, which process comprises forming a fixed bed by packing the acidic cation exchange resin into a reactor and, before starting a reaction, introducing an aqueous solution of an alkylsulfonic acid and an aqueous solution of the sulfur compound having nitrogen into the reactor and circulating both aqueous solutions through the reactor. After the acidic cation exchange resin is uniformly and intermediately neutralized, corrosion of apparatuses does not take place and an acid does not remain after washing with water or substitution with phenol.
