Description

Application

Isosorbide dimethyl ether (DMI), a sustainable solvent, is widely used in various cosmetic and pharmaceutical formulations.[1]
General applications:

• DMI can be used as an alternative green solvent for epoxidation of cyclooctene[2], Baylis–Hillman reaction of isomaltulose-derived aldehydes with α,β-unsaturated ketones[3] and also in solid-phase synthesis.[4]
• It can be used as a coalescent for water-borne paints, where it acts as a co-solvent during the water loss phase and as a coalescing agent during the film formation.[5]
