摘要: A process for preparing aromatic bisphenols, wherein the method comprises reacting an aromatic hydroxy compound with an alkylating agent having a functionality of two in the presence of a catalyst system. The catalyst system used for the process is selected from the group consisting of a heteropolyacid compound, a clay, a functionalized metal oxide catalyst and combinations of the foregoing.
