Bulk Dimethyl Ether Dme Supplier Industrial Solvent & LPG Substitute

Main uses of dimethyl ethre (DME)

1. Replacement of chlorofluorocarbons as aerosols

As the environmental awareness of countries around the world is increasing, chlorofluorocarbons, which were previously used as aerosols in the aerosol industry, are gradually being replaced by other harmless substances.

2. Used as a refrigerant and foaming agent

Due to the low boiling point, high heat of vaporization, good vaporization effect of DME, and its condensation and evaporation characteristics are close to those of chlorofluorocarbons, DME is very promising as a refrigerant. Domestic and foreign countries are actively developing its application in refrigerators, air conditioners, food preservatives, etc. to replace Freon. DME is used as a foaming agent. Foreign countries have successively developed DME as a foaming agent for polystyrene, polyurethane, and thermoplastic polyester foams. The foamed products have uniform pore size, and their flexibility, pressure resistance, crack resistance and other properties have been enhanced.

3. DME as fuel

DME has a vapor pressure similar to that of liquefied petroleum gas. It becomes liquid at low pressure and gaseous at normal temperature and pressure. It is flammable and has low toxicity. In addition, DME has a high cetane number (about 55). As a substitute for liquefied petroleum gas and diesel in automobile fuel, the conditions are ripe. As it is an excellent clean energy, it has been widely valued at home and abroad. In the next ten years, the application of DME as a fuel will have an immeasurable potential market, and its application prospects are very optimistic. It can be widely used in civilian clean fuels, automobile engine fuels, and alcohol fuels.

Production method of DME

Methanol dehydration method

Methanol dehydration method is one of the main methods for producing Methoxymethane. This method uses methanol to undergo a dehydration reaction under the action of a catalyst (such as γ-alumina, ion exchange resin, etc.) to produce DME. The reaction equation is: 2CH3OH → CH3OCH3 + H2O. This method has a simple process and low cost, and is currently the mainstream technology for industrial production of dimethyl ethre.

Synthesis gas production method

The synthesis gas production method uses synthesis gas (a mixture of CO and H2) as a raw material to prepare Methoxymethane through a one-step or two-step method. The one-step method refers to the direct generation of from synthesis Methoxymethane gas under the action of a catalyst, and the reaction equation is: 2CO + 4H2 → CH3OCH3 + H2O. The two-stage method refers to first converting synthesis gas into methanol, and then dehydrating methanol to produce Methoxymethane. This method has the advantages of a wide range of raw material sources and high production efficiency.

Market prospects of Methoxymethane

With the growth of global energy demand and the improvement of environmental protection awareness, dimethyl Methoxymethane, as a clean energy and important chemical raw material, has shown a rapid growth trend in market demand. Especially in China, the DME industry has received strong support from the government and has huge market potential in the future. With the continuous improvement of production technology and the continuous expansion of application fields, the economic and social benefits of it will be further improved.

Conclusion

Due to its unique physical and chemical properties, Methoxymethane has a wide range of applications in fuel, refrigerant, foaming agent and chemical raw materials. Methanol dehydration method and synthesis gas preparation method are the main production methods, IT has broad market prospects. In the future, with the continuous advancement of technology and the continuous expansion of application scope, Methoxymethane is expected to play a more important role in modern industry and promote the sustainable development of economy and environment.
