Abstract

Disclosed herein are processes comprising contacting isosorbide with hydrogen in the presence of a first hydrogenation catalyst to form a first product mixture comprising tetrahydrofuran-2,5-dimethanol. The processes can further comprise heating the first product mixture in the presence of hydrogen and a second hydrogenation catalyst to form a second product mixture comprising 1,6-hexanediol. The first and second hydrogenation catalysts can be the same or different.
