What is dimethyl ether?

Dimethyl ether is a basic chemical raw material, Also known as dme gas aerosol propellant, dme propellant, dimethyl ether aerosol, structural formula: CH3OCH3, has certain toxicity and fishy smell, because of its good characteristics of easy compression, condensation, vaporization, etc., it has been widely used in chemical industries such as pharmaceuticals, fuels, and pesticides. One of the main uses is as a propellant for aerosols, aerosols and spray paints. Due to the rapid development of China's aerosol industry, its market as an aerosol is huge.

Production characteristics of aerosol grade dimethyl ether:

The characteristic of aerosol-grade dimethyl ether is that it uses process wastewater, steam and steam condensate with low thermal energy generated during the production of fuel-grade dimethyl ether as the energy source for the rectification operation, and effectively utilizes the remaining energy of the main device. energy, save energy consumption, and produce high-purity aerosol-grade dimethyl ether products. In the present invention, aerosol-grade dimethyl ether uses fuel-grade dimethyl ether as a raw material, and removes heavy components such as water, methanol, and olefins, etc. Light components, and then remove moisture and trace organic amines and other impurities through the adsorption operation of the dehydration tower and the deamination tower, and finally obtain a high-purity aerosol-grade dimethyl ether product. The trace amount of organic amine in the aerosol grade dimethyl ether is qualitatively quantified by gas chromatography.

The role of aerosol grade dimethyl ether:

From the perspective of dimethyl ether consumption, aerosol propellant is one of the main uses of dimethyl ether. Since the 1960s, aerosol products have been popular with consumers due to their unique packaging characteristics. In the past, a large number of aerosol products used chlorofluorocarbons as propellants. When they were used, they were all released into the atmosphere, causing serious damage to the atmospheric ozone layer, thereby affecting human health, animal and plant growth, and the earth's ecological environment. Therefore, all countries in the world are working hard to find substitutes for Erbauxin. Since 1988, my country has banned the use of chlorofluorocarbons (except medical supplies) as propellants in aerosols. Alternatives to chlorofluorocarbons now include LPG, DME, compressed gas (CO2, N2, N2O), hydrochlorofluorocarbons, hydrofluorocarbons and other substances. With its good performance in the aerosol industry, DME is gradually replacing other aerosols and becoming the main body of the fourth-generation propellant. It can also be used as an air freshener, insect repellent, foam caulk, streamers, and more.

Storage and transportation of aerosol grade dimethyl ether:

Store

Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Storage temperature should not exceed 30°C. It should be stored separately from oxidants, acids, and halogens, and should not be mixed. Explosion-proof lighting and ventilation facilities are adopted. Prohibit the use of mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment.

Transportation

The safety cap on the steel cylinder must be worn when transported in steel cylinders. The steel cylinders are generally placed flat, and the bottle mouths should face the same direction, and cannot be crossed; the height should not exceed the vehicle's guardrail, and should be locked with a triangular wooden pad to prevent rolling. During transportation, the transport vehicle should be equipped with corresponding types and quantities of fire-fighting equipment. The exhaust pipe of the vehicle carrying this item must be equipped with a fire arresting device, and it is forbidden to use mechanical equipment and tools that are prone to sparks to load and unload. It is strictly forbidden to mix and transport with oxidants, acids, halogens, food chemicals, etc. In summer, it should be transported in the morning and evening to prevent sun exposure. Stay away from fire and heat sources during stopovers. When transporting by road, follow the prescribed route, and it is forbidden to stay in residential areas and densely populated areas. It is forbidden to slip when transporting by rail.
