It has a rather high melting temperature around 36 °C and is therefore usually mixed with other solvents with low melting temperatures, for example, diethyl carbonate (DEC), DMC, or ethyl methyl carbonate (EMC).
WebThis implied a promoting role of DME on sooting when small amount of DME is mixed to ethylene. As the pressure increased, the sooting region generally expanded. Specifically, the range of beta in promoting soot formation extended with pressure. This implies that a strategy in reducing soot by adding DME to ethylene at high pressures required a ...
