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.

Abstract: Provided herein are methods for preparing alkylfurans, such as 2,5-dialkylfurans and 2-alkylfurans. Furfural or 5-alkylfurfural can be reacted with aniline or diaminobenzene, or derivatives thereof, to form the corresponding imine, which can be reduced to form alkylfurans and to regenerate the aniline or diaminobenzene, or derivatives thereof. The alkylfuran may be, for example, 2,5-dimethylfuran or 2-methylfuran.

Abstract translation: 本文提供了制备烷基呋喃的方法，例如2,5-二烷基呋喃和2-烷基呋喃。 糠醛或5-烷基糠醛可以与苯胺或二氨基苯或其衍生物反应形成相应的亚胺，其可以还原形成烷基呋喃并使苯胺或二氨基苯或其衍生物再生。 烷基呋喃可以是例如2,5-二甲基呋喃或2-甲基呋喃。
