Di-Methyl Ether is the compound name for the compound CH₁OCH₁, with the abbreviation CCHH₀. It's the simplest compound, it's a yellowish colored gas that is an aerosol propellant and a precursor to more complex organic substances. It's an isomer of acetaldehyde. The synthesis gas transformed into methanol in the presence of catalysts with consequent methanol dehydration under various catalysts namely silica-aluminum. Since the liquefaction of di-methyl ether is comparatively easy, it is convenient to store and transport. DME is typically used in automotive motors, power generation, and domestic applications. Acetaldehyde is used in many things such as paint, ink, and other organic products and also as a gasoline additive. It's been used for years as an oxidizing agent for rocket propellants and has even been used in space for its oxidizing properties.
