Abstract: Disclosed herein is a method of making and/or isolating isoidide, a composition including a mixture including non-esterified isoidide and one or both compounds selected from the group consisting of esterified isosorbide and esterified isomannide and a method of using of such composition for making and/or isolating isoidide. Further disclosed herein is a method including a step of selective esterification of a mixture of dianhydrohexitol isomers including isoidide for separating isoidide from said mixture of dianhydrohexitol isomers. Moreover, a method of making a polymer including isoidide monomers or modified isoidide monomers is disclosed.
