What is the Common Name of Dimethyl Ether?

Dimethyl ether (DME) is an organic chemical raw material, existing as a colorless, easily liquefiable gas with a slightly luminous flame upon combustion. It is soluble in water, gasoline, carbon tetrachloride, benzene, chlorobenzene, acetone, and methyl acetate. Its chemical formula is C₂H₆O, and it is commonly referred to as Methyl Ether or simply DME (Dimethyl Ether).

In addition, dimethyl ether is known by various other identifiers:

CAS Number: 115-10-6

MDL Number: MFCD00008494

EINECS Number: 204-065-8

RTECS Number: PM4780000

Other names include: Dimethyl Oxide, Methyl Ether, Methyl Oxide, (CH₃)₂O, Demeond, Dymel A, Dymela, Ether, dimethyl, Ether, methyl.

At standard conditions, dimethyl ether exists as a colorless gas with a slight ether odor or as a compressed liquid, featuring excellent miscibility and easy liquefaction. These properties make DME increasingly prominent in the aerosol industry, where it is widely used in the production of air fresheners, insecticides, foam sealants, and other aerosol products.

Applications of Dimethyl Ether in Insecticides

DME is primarily used in water-based insecticidal aerosols. Its high solubility in water allows it to form a uniform single-phase solution inside the container. This means water-based insecticidal aerosols using DME as a propellant do not require shaking before use, enhancing convenience. Furthermore, DME can be blended with other insecticidal ingredients, improving efficacy while reducing toxicity to humans.

Why DME is Used as a Propellant

Low Boiling Point: DME evaporates easily at room temperature, generating sufficient pressure to propel the active ingredients.

High Vapor Pressure: Ensures stable aerosol formation, allowing uniform distribution of the product.

Solubility: DME can dissolve many substances, enabling homogeneous mixtures with other insecticidal ingredients.

Ease of Preparation and Low Cost: Simplifies manufacturing and reduces production expenses.

Safety Considerations

The main concerns regarding DME in insecticides are related to flammability and explosiveness. DME can form explosive mixtures with air and poses a fire or explosion risk when exposed to sparks or high heat. In high-temperature environments, internal pressure in the container can rise, and if the container or seals are compromised, explosions may occur.

However, when used correctly, dimethyl ether is considered safe as a common organic solvent. Following strict safety regulations and environmental standards ensures the safety and stability of products containing DME.
