What is the common name of dimethyl ether? 

Dimethyl ether is a relatively complex organic molecule with a chemical formula of CH3OCH3. Dimethyl ether, also known as methyl ether and methyl ether, is soluble in water, gasoline, carbon tetrachloride, benzene, chlorobenzene, acetone and methyl acetate, and is mainly used as solvents, refrigerants, sprays, etc. Dimethyl ether has a wide range of applications in many fields due to its unique physical and chemical properties, however, there is no clear answer in history as to who first discovered and named dimethyl ether. The history of human use of dimethyl ether can be traced back to the early 20th century, and the following is a historical review of the use of dimethyl ether.

(1) Early detection and research

Dimethyl ether was first synthesized in 1856, but it was not until the 20th century that it gradually gained attention. Originally, dimethyl ether was mainly used as a solvent and extractant. Its excellent solubility makes it very useful in chemical analysis and laboratory operations. In addition, dimethyl ether has also been used as an anesthetic, but this use has not been widely promoted due to its instability and toxicity.

(2) The rise of the energy sector

In the 70s of the 20th century, the global energy crisis broke out, and dimethyl ether began to attract attention as a potential alternative energy source. Its combustion characteristics are similar to those of LPG, but it is cleaner and emits fewer pollutants. As a result, dimethyl ether is widely studied as a fuel for automobiles and power plants.

In the 21st century, the application of dimethyl ether in the energy field has been further expanded. Countries such as China and India began mass production and use of dimethyl ether as a civilian fuel for home cooking and heating. The liquefaction properties of dimethyl ether make it advantageous in storage and transportation, and it is gradually becoming an alternative to liquefied petroleum gas.

(3) The development of industrial applications

In addition to the energy sector, the use of dimethyl ether in industry is also expanding. Dimethyl ether is an important chemical raw material used in the production of a variety of chemicals, such as formaldehyde, acetic acid, and methyl tert-butyl ether. In addition, dimethyl ether can also be used as a foaming agent to replace freon in refrigeration systems and the production of foams, which is more environmentally friendly.

(4) Pharmaceutical and daily chemical fields

In the pharmaceutical field, dimethyl ether is used as a pharmaceutical solvent and spray carrier due to its low toxicity and good solubility. Many aerosol medications, such as asthma inhalers, use dimethyl ether as a propellant. In addition, dimethyl ether is used in cosmetics and perfume production as a solvent and spray ingredient.

With the growing global demand for clean energy and environmental protection technologies, the application prospect of dimethyl ether is still broad. Researchers are further researching the catalytic conversion technology of dimethyl ether to improve its energy efficiency and environmental friendliness of the production process. In addition, the application of dimethyl ether in fuel cells and biomass conversion has also shown great potential. With the progress of science and technology, the application field of dimethyl ether will continue to expand and make greater contributions to the development of human society.
