Thermal decomposition of dimethyl ether (DME) has been studied in a rapid compression machine over a temperature range1060–1920 K. The main products (H2, CO, CH4, and formaldehyde) and minor products of reaction have been identified. Some of them like propane, propene, allene, methylacetylene, butadiene-1,3, vinylacetylene, diacetylene, cyclopentadiene, benzene and toluene were identified for the first time. It is shown that ethylene yield remains constant in the temperature range 1700–1920 K at the conversion degree of DME exceeding 95% along with the decrease of methane and ethane yields and the increase of acetylene yield.
