Dimethyl ether is an organic compound from the group of ethers. It is a colourless gas with a characteristic odour, moderately soluble in water.
The product in aerosol is used as a propellant (factor for discharging content). It is used instead of the previously applied CFCs, as it has no harmful effect on the ozone layer. The product is therefore environmentally friendly. In addition, 100% of the energy needed to produce dimethyl ether comes from renewable sources (solar and wind energy).
DME in the aerosol present in a concentration of not less than 99.99%. It is produced in the dehydration of methanol followed by DME rectification.
Recommended use:
household chemicals,
aerosol cosmetic products,
lacquers and spray paints,
assembly foams,
foamed polystyrene foams.
Dimethyl ether has a good miscibility with water and the ability to dissolve polymers. It is also compatible with other solvents and propellants. Very high solubility of the product makes it popular as a propellant in spray paints. It improves their properties and facilitates application onto various surfaces.
DME is one of the most popular propellants, which are also used in the production of polyurethane foams. Its undoubted advantage in this application is the ability to simultaneously pump the propellant and solvent, which reduces and streamlines the production process.
High distribution coefficient allows dimethyl ether to be used also in the production of polystyrene foam (XPS). The properties of the product make it suitable for the production of boards with desired parameters, at lower production costs.
Other possible uses:
Tanning leather using DME
This method involves soaking the leather that requires degreasing and/or dehumidifying in one or more solvents. In this process, dimethyl ether is used as the solvent. Degreasing and/or dehumidifying is used for cow, pig, sheep or goat leather. The addition of DME solvent ensures the effectiveness of cleaning and improves the ecological safety of the process.
The refrigerant for cooling/ refrigerating equipment
Dimethyl ether as a mixture with ammonia (mass ratio of 40%/60%) may be used in freezing devices. The refrigerant is called R723. The use of such a mixture increases the efficiency of cooling devices. Mineral oil has a limited solubility in R723 mixture and is capable of operating with copper. These properties allow engineers to create a device with a low yield, but more effective than those that operate with currently manufactured refrigerants. By replacing 40% of ammonia with dimethyl ether in the existing refrigeration equipment, you can limit the ammonia content without sacrificing performance of the devices.
