Dimethyl ether (DME) is an organic compound with molecular formulae CH3OCH3 and a clean burning hydrocarbon fuel with no carbon-carbon bond. It is the simplest ether and is a gas in normal state. It is colorless and non poisonous if inhaled by humans. DME is commercially manufactured by first converting coal or natural gas to syn gas, which is converted to methanol in presence of a catalyst. Methanol is then dehydrated to form DME as an end product. A significant portion of DME is also manufactured by simply dehydrating marketed methanol in order to avoid huge plant establishment cost. The uses of DME vary by regions. In general, it is used for blending in liquefied petroleum gas (LPG) in a pre-de...
