Abstract

Disclosed is a process for the preparation of isoidide from isosorbide. An aqueous solution of isosorbide is subjected to epimerization in the presence of hydrogen under the influence of a catalyst comprising ruthenium on a support, preferably a carbon support. The process of the invention can be conducted using a relatively low hydrogen pressure, and leads to a desired distribution of epimers, favoring isoidide over isomannide and isosorbide.
