摘要： Embodiments of the present disclosure generally relate to processes for forming bisphenols and epoxy resin compositions. In an embodiment, a process for making an epoxy resin composition is provided. The process includes reacting a mixture comprising a catalyst, a monophenol, and an aldehyde or ketone, the mixture comprising a stoichiometric excess of the aldehyde or ketone to the monophenol, and forming a reaction product with the reaction mixture, the reaction product comprising a bisphenol. The process further includes removing water and unreacted aldehyde or ketone from the reaction product, and converting the reaction product comprising the bisphenol to an epoxy resin composition, wherein, after reacting the mixture and before converting the reaction product, the process is free of washing, drying, solid-liquid separation, or combinations thereof.
