Abstract
Methods are provided for the purification of isoidide. The methods comprise subjecting an at least partially deionized isoidide composition comprising isoidide and other isohexides to chromatographic separation of isoidide from other isohexides, removal of solvent from the isoidide, and crystallization of the isoidide. Isoidide of monomer-grade purity is obtained.
