Abstract: Embodiments of the present disclosure generally relate to processes for forming epoxy resin compositions and processes for separating substrates from complex mixtures. In an embodiment, a process for making an epoxy resin composition is provided and includes: reacting a mixture comprising a substrate, an epihalohydrin, and a catalyst to form a first composition comprising a halohydrin reaction product; introducing an alkaline reagent with the first composition to form a second composition comprising an epoxy resin product; introducing a liquid epoxy resin with the second composition to form a resin mixture; and removing unreacted epihalohydrin from the resin mixture to form the epoxy resin composition.
