Methoxymethane

Methoxymethane is an organic compound with the chemical formula C2H6O and CAS number 115-10-6. Also known as dimethyl ether, it is the simplest ether compound with a molecular weight of 46.07 g/mol. This substance is classified as a flammable gas under pressure, requiring careful handling due to its hazardous properties. It serves as an important chemical intermediate and fuel component in various industrial applications.

Methoxymethane is a colorless gas at room temperature and atmospheric pressure with a characteristic ethereal odor. It has a boiling point of -24.8°C and is highly volatile. The compound is moderately soluble in water and miscible with most organic solvents. Due to its gaseous state under normal conditions, it requires pressurized storage. Its low molecular weight and ether structure contribute to its high volatility and flammability.

Methoxymethane serves as an aerosol propellant, refrigerant, and fuel additive in various industrial applications. It is used as a solvent in chemical processes and as an intermediate in organic synthesis. The compound finds application in the production of other chemicals and as a clean-burning alternative fuel. Its properties make it suitable for specialized applications requiring low-temperature volatility and clean combustion characteristics.

Methoxymethane requires careful handling as a flammable gas under pressure, necessitating appropriate personal protective equipment including safety glasses, protective gloves, and flame-resistant clothing. Work areas must be well-ventilated and free from ignition sources. Use only explosion-proof electrical equipment and ensure proper grounding of all equipment. Avoid direct contact with skin and eyes, and never allow the gas to accumulate in confined spaces.

Methoxymethane must be stored in approved pressure vessels designed for flammable gases, kept in cool, dry, well-ventilated areas away from heat sources and ignition points. Storage areas should be equipped with appropriate fire suppression systems and gas detection equipment. Keep containers upright and secure to prevent tipping. Separate from oxidizing agents and incompatible materials according to chemical compatibility guidelines.

Methoxymethane exposure requires immediate action: for skin contact, remove contaminated clothing and flush affected areas with water for at least 15 minutes. In case of eye contact, rinse thoroughly with water and seek medical attention. If inhaled, move the person to fresh air immediately and provide artificial respiration if breathing stops. For suspected frostbite from liquid contact, do not rub affected areas and seek immediate medical attention.

Methoxymethane disposal must comply with local, national, and European waste regulations as a hazardous substance. Contact licensed waste disposal companies specialized in flammable gas handling. Never release the gas directly into the atmosphere or sewage systems. Empty containers should be properly purged and handled according to pressure vessel disposal regulations. Consult local environmental authorities for specific disposal requirements and approved disposal facilities.

Methoxymethane is classified under ADR Class 2 for transport as a flammable gas, requiring specialized packaging and documentation according to dangerous goods regulations. Transportation must use approved pressure vessels and vehicles equipped for hazardous gas transport. Drivers need appropriate ADR certification for Class 2 substances. Ensure proper labeling with GHS02 and GHS04 pictograms and maintain required transport documents throughout the journey.

Methoxymethane is regulated under European CLP and REACH regulations but is not classified as a Substance of Very High Concern (SVHC). It requires hazard classification as Flammable Gas Category 1 and Pressure Gas with corresponding safety data sheets. Industrial users must comply with workplace safety regulations for flammable gases and maintain appropriate risk assessments and safety measures according to local occupational health guidelines.

Methoxymethane is available through OYSI, a European distributor of technical chemicals specializing in hazardous substances. OYSI provides proper packaging, documentation, and regulatory compliance for methoxymethane distribution across Europe. As a specialized chemical requiring careful handling and transport, it is essential to work with experienced distributors who understand the safety requirements and can ensure proper delivery of this flammable gas under pressure.
