Product Description

Methoxymethane product introduction

Product description

Dimethyl Methoxymethane (molecular formula: C2H6O, indicative formula: CH3OCH3, DME), also known as methyl ethre and methoxymethane, is the simplest aliphatic ethre. It is a derivative of the dehydration condensation of two molecules of methanol. At room temperature, it is a colorless, non-toxic gas or compressed liquid with a slight ethre aroma. It is an important organic chemical product and chemical intermediate.

Characteristics

· Efficient and Clean: DME has high energy density and low pollution emissions, with no residue or black smoke during combustion.

· Good Solubility: It is miscible with most organic solvents, facilitating use in various chemical reactions.

· Stable Chemical Properties: It is resistant to reaction with acids and bases but can undergo combustion and oxidation reactions at high temperatures or in the presence of catalysts.

 

 

Characteristics  

Methoxymethane has excellent combustion characteristics, high cetane number, less pollution, no damage to the atmospheric ozone layer, and is easily degraded in the troposphere. It can be widely used in automobile fuel.

Methoxymethane can be used as a propellant, foaming agent, solvent, extractant, etc. for aerosols. High concentrations of DME can be used as an anesthetic.

It is also used in refrigerants as a substitute for Freon.

Advantages / Selling Points

· Clean Energy: Emits no soot, making it ideal for applications where environmental concerns are paramount.

· Versatile Usage: Compatible with various industrial, automotive, and domestic applications.

· Cost-Effective: An economical alternative to liquefied petroleum gas (LPG) and diesel.

· Safe Storage: Stable under normal conditions, with minimal risk of degradation.

· Reliable Supply: Produced using abundant resources like methanol or natural gas, ensuring consistent availability.

Applications

· Fuel:

o Replacement for LPG in domestic and industrial cooking.

o Alternative diesel fuel for automotive and power generation.

· Aerosol Propellant:

o Widely used in cosmetics, pharmaceuticals, and household sprays.

· Chemical Feedstock:

o Used in the synthesis of dimethyl sulfate, acetic acid, and other intermediates.

· Refrigerant:

o Acts as an efficient cooling agent in refrigeration systems.

· Welding and Cutting:

o Fuel for oxy-DME welding applications.

Technology

The Methoxymethane project adopts advanced methanol gas-phase catalytic dehydration technology to produce fuel-grade Methoxymethanewith a concentration of more than 99.0%. The fuel-grade  is further separated through a lightness removal tower (using high-efficiency corrugated rolled perforated plate filler) to obtain refined with a concentration of 99.9% and high-purity  with a concentration of 99.99%.

 

Theory

The chemical stability and low molecular weight of DME make it highly reactive for applications in energy and chemical processes. Its combustion reaction is represented as follows:
CH₃OCH₃ + 3O₂ → 2CO₂ + 3H₂O + Energytext{CH₃OCH₃ + 3O₂ → 2CO₂ + 3H₂O + Energy}CH₃OCH₃ + 3O₂ → 2CO₂ + 3H₂O + Energy

 

 Service

· Customized Solutions: Tailored specifications for different industries.

· Logistics Support: Safe and efficient transport of DME worldwide.

· Technical Assistance: On-site and remote troubleshooting for your specific applications.

· 24/7 Customer Support: Dedicated team to address your queries anytime.

 

 

Production Process

The production of DME involves:

1. Methanol dehydration under controlled conditions using advanced solid acid catalysts.

2. Purification of the final product to ensure high purity levels (>99.99%).

3. Storage in pressurized tanks for distribution.
