What is the common name of dimethyl ether? 

Dimethyl ether is an organic raw material, colorless and easy to liquefy gas, and the flame is slightly bright when burning. Soluble in water, gasoline, carbon tetrachloride, benzene, chlorobenzene, acetone and methyl acetate. Dimethyl ether has the chemical formula C₂H₆O, which is also commonly known as methyl ether or DME (Dimethyl Ether), in addition, dimethyl ether has many other names, such as: its CAS number is 115-10-6, MDL NUMBER IS MFCD00008494, EINECS NUMBER 204-065-8, RTECS NUMBER is PM4780000, IN ADDITION, DIMETHYL OXIDE; METHYL ETHER； METHYL OXIDE； (CH3)2O； demeond； Dymel A； dymela； Ether, dimethyl； Ether and methyl are also the "nicknames" of dimethyl ether.

Dimethyl ether is a colorless, slightly ether-flavored gas or compressed liquid in the standard state, with excellent solubility and easy liquefaction characteristics. These properties have made dimethyl ether gradually emerging in the aerosol industry, and is widely used in the production of air fresheners, pesticides, foam caulks and other aerosol products.

In the field of insecticides, the application of dimethyl ether is mainly concentrated in water-based insecticidal aerosols. Due to the excellent compatibility between dimethyl ether and water, a uniform single liquid phase can be formed in the tank, so that the water-based insecticidal aerosol using dimethyl ether as a propellant does not need to be shaken when used, thus improving the convenience of use. In addition, dimethyl ether can also be compounded with other insecticidal ingredients to improve the insecticidal effect while reducing toxicity to the human body.

In addition, dimethyl ether is commonly used as a propellant in insecticides due to its following properties:

(1) Lower boiling point: Dimethyl ether has a low boiling point, which makes it easy to evaporate at room temperature, so as to provide enough pressure in the aerosol to push the drug to be sprayed.

(2) Increase vapor pressure: Dimethyl ether has a higher vapor pressure, which helps to form a stable aerosol in the aerosol and ensures that the drug can be evenly distributed in the target area.

(3) Solubility : Dimethyl ether has a certain solubility to many substances, which allows it to mix with other pesticide components to form a homogeneous preparation.

(4) Easy to prepare and cheap to eat.

Much of what makes the use of dimethyl ether controversial is the safety of dimethyl ether, and the use of dimethyl ether in pesticides is not without risk. Dimethyl ether has the characteristics of flammability and explosiveness, and can form an explosive mixture when mixed with air, and there is a risk of combustion and explosion in case of sparks and high heat. Especially in the high temperature environment, the pressure of dimethyl ether in the tank increases, and if there are defects in the tank body or seal, it is easy to cause explosion accidents. However, as a commonly used organic solvent, dimethyl ether is considered safe under appropriate conditions of use, and the safety and stability of the product can be ensured as long as the relevant safety regulations and environmental protection standards are strictly adhered to.
