Abstract
Embodiments in accordance with the present invention provide alicyclic diepoxide compounds and methods for forming such compounds. Such methods encompass charging a reaction vessel with an appropriate diene and an appropriate dienophile and causing such to react to form and recover a desired alicyclic diepoxide precursor where such precursor is subsequently epoxidized. Such compounds encompass alicyclic diepoxides having purities of at least 95 percent or at least 98 percent with respect non-isomeric residues and are essentially free of any isomeric alicyclic diepoxide residues.
