As DME has been commercially used as a high-grade propellant for various health care product, its environmental, health and safety (EHS) characteristics are rather “impeccable” (vs. conventional petroleum-based fuels) for its use as a multi-purpose fuel and as a chemical intermediate. DME is a flammable, thermallystable liquid like LPG and can be handled like LPG with similar safety guidelines and codes as LPG. A few key physical properties of DME are compared with specific conventional fuels in Table 1.
