Origin, Properties and Introduction of Isosorbide Dimethyl Ether

Origin of Isosorbide Dimethyl Ether

Isosorbide dimethyl ether (ISDM) is derived from isosorbide, a biobased compound obtained through the dehydration of sorbitol, which itself originates from glucose. The production of isosorbide involves a catalytic process that removes water from sorbitol, resulting in a bicyclic diol with two hydroxyl groups. Methylation of these hydroxyl groups produces isosorbide dimethyl ether.

This synthesis pathway makes Isosorbide dimethyl ether a renewable compound and a promising alternative to petrochemical derivatives for various industrial applications.
