Dimethyl ether (DME), also known as methoxymethane, is the organic compound with the formula CH 3 OCH 3, simplified to C 2 H 6 O. The simplest ether, it is a. Dimethyl ether DME Fact Sheet. Introduction and basic data on DMEProduction process for DMEState of the Art for DME production. Applications of DMEEC- funded projects on DMEMajor stakeholders in DME in the EUIntroduction Dimethyl ether (typically abbreviated as DME), also known as methoxymethane, wood ether, dimethyl oxide or methyl ether, is the simplest ether. It is a colourless, slightly narcotic, non- toxic, highly flammable gas at ambient conditions, but can be handled as a liquid when lightly pressurized. The properties of DME are similar to those of Liquefied Petroleum Gas (LPG). DME is degradable in the atmosphere and is not a greenhouse gas. Safety Data Sheet Material Name: DIMETHYL ETHER SDS ID.

The syngas is then converted into DME via a two- step synthesis, first to methanol in the presence of catalyst (usually copper- based), and then by subsequent methanol dehydration in the presence of a different catalyst (for example, silica- alumina) into DME. The following reactions occur: 2. H2+ CO CH3. OH2. CH3. OH CH3. OCH3 + H2. OCO+H2. O CO2+H2. Alternatively, DME can be produced through direct synthesis using a dual- catalyst system which permits both methanol synthesis and dehydration in the same process unit, with no intermediate methanol separation, a procedure that, by eliminating the intermediate methanol synthesis stage, the licensors claim promises efficiency advantages and cost benefits. The raw material used is black liquor, a high- energy residual product of chemical paper and pulp manufacture which is usually burnt to recover the spent sulphur. Applications. Due to its good ignition quality, with a high cetane number, DME can be used in diesel engines as a substitute for conventional diesel fuel. MATERIAL SAFETY DATA SHEET Ethyl Ether 1.

MSDS: 255 Revision Date: 10.31.13 Revision Number: 3.0 Initials: EF.However, compared to diesel fuel DME has a lower viscosity (insufficient), and poor lubricity. Like LPG for gasoline engines, DME is stored in the liquid state under relatively low pressure of 0. MPa. This helps to limit the number of modifications required to the engine. Still, some slight engine modifications are necessary, primarily relating to the injection pump and the installation of a pressure tank, similar to that for LPG. The fuel line must also be adapted with specific elastomers. As part of the FP7 project Bio. DME, under the leadership of the Volvo Group, DME production is being optimized, especially for use as a transport fuel. EC- funded projects on DME See R& D Funding page for further project details.
