Polyoxymethylene dimethyl ether 3 has been regarded as a promising additive for reducing soot emissions in diesel engines. There are two pathways to produce ethanol: chemical processes and biological processes. It can asphyxiate by the displacement of air. It is mainly used as a fuel substitute or blended fuel with LPG or diesel. This may involve “dropping in” a sustainable version of the secondary fuel, such as biodiesel. In addition, rDME is also a cost-effective carrier for hydrogen, making it easy to deliver this renewable fuel for the growing hydrogen fuel cell vehicle industry. PubChem Compound Database, U.S. National Library of Medicine, Available here. Ethanol is highly flammable; thus, it is used as a fuel as well. What is Dimethyl Ether?
