Specification Parameters

DME's specification parameters include its chemical formula (C2H6O), CAS registry number (115-10-6), relative molecular mass (46.069), melting point (-141.49°C), boiling point (-24.84°C), critical temperature (400.1K), critical pressure (5.37MPa), gas density (1.908kg/m³ at 101.325kPa), liquid density (0.655g/cm³ at 25°C), solubility parameter (17.572(J/em³)^0.5), flash point (-41.1°C), ignition point (350°C), and explosion limits in air (3.4%~18%).

Characteristics

DME is easily compressible, condensable, and vaporizable, making it suitable for various applications. It is miscible with both polar and non-polar solvents, exhibiting excellent solubility properties. Additionally, DME's combustion performance is outstanding, with high thermal efficiency and minimal residue or soot production during combustion.

Advantages

1. Environmental Benefits: DME's clean combustion process produces fewer pollutants, contributing to reduced atmospheric pollution and aligning with global environmental trends.
2. Economic Efficiency: DME production utilizes diverse raw materials such as coal, natural gas, and biomass, with mature production processes and relatively low costs. Market demand for DME continues to grow, particularly in the alternative energy sector, offering significant economic benefits.
3. Safety Performance: DME has high storage and transportation safety, with a low risk of leakage or explosion accidents. Its combustion process is clean and safe, producing no residue or soot, reducing fire hazards.
4. Versatile Applications: DME's multiple uses, including as an aerosol propellant, refrigerant, solvent, and fuel, enhance its competitiveness in the market and satisfy diverse industrial needs.

Production Process

DME production primarily involves two methods: the two-step process (methanol dehydration to DME) and the one-step process (direct synthesis of DME from syngas). The two-step process, which has become the mainstream method for DME production, involves the dehydration of methanol to produce DME.

Theoretical Basis

DME's use as a fuel is based on its high combustion efficiency and minimal emissions, making it an environmentally friendly option. Additionally, DME's solubility and miscibility properties provide unique advantages in chemical synthesis and solvent applications, making it a versatile and valuable chemical compound.
