PRODUCT OVERVIEW
Dimethyl ether is an organic compound that is a colorless and odorless flammable gas under standard conditions, with the chemical formula C2H6O. Mixing with air can form explosive mixtures, which are prone to combustion and explosion in contact with heat, sparks, flames, or oxidants. Peroxides with potential explosion hazards can be generated in contact with air or under light conditions, with a higher density than air. They can diffuse to a considerable distance at lower points and ignite when encountering a fire source. If encountering high heat, the pressure inside the container increases, posing a risk of cracking and explosion.

TORAGE METHOD
Store in a cool and ventilated warehouse. Keep away from sparks and heat sources. The temperature of the warehouse should not exceed 30 ℃. It should be stored separately from oxidants, acids, and halogens, and should not be mixed for storage. Using explosion-proof lighting and ventilation facilities. Prohibit the use of mechanical equipment and tools that are prone to sparks. The storage area should be equipped with emergency response equipment for leaks. When transporting steel cylinders, it is necessary to wear the safety helmet on the cylinder. Steel cylinders are generally placed flat, and the bottle mouth should be facing the same direction and not crossed; The height should not exceed the protective fence of the vehicle, and triangular wooden pads should be used to secure it to prevent rolling. During transportation, transportation vehicles 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 flame retardant device, and it is prohibited to use mechanical equipment and tools that are prone to sparks for loading and unloading. It is strictly prohibited to mix and transport with oxidants, acids, halogens, edible chemicals, etc. Transportation should be carried out in the morning and evening in summer to prevent direct sunlight exposure. During a stopover, stay away from sparks and heat sources. During road transportation, it is necessary to follow the prescribed route and stop in residential and densely populated areas. It is prohibited to slide during railway transportation.APPLICATION AREA
Dimethyl ether, as an emerging basic organic chemical raw material, has many unique uses in the pharmaceutical, fuel, pesticide and other chemical industries due to its excellent compressibility, condensation, and gasification characteristics. High purity dimethyl ether can replace Freon as an aerosol spray and refrigerant, reducing pollution to the atmospheric environment and ozone layer damage. Due to its good water solubility and oil solubility, its application range is greatly superior to petroleum chemicals such as propane and butane. Replacing methanol as a new raw material for formaldehyde production can significantly reduce the cost of formaldehyde production and demonstrate its superiority in large-scale formaldehyde plants. As a civilian fuel gas, its performance indicators such as storage and transportation, combustion safety, premixed gas calorific value, and theoretical combustion temperature are superior to those of liquefied petroleum gas. It can be used as a peak shaving gas for urban pipeline gas and a mixture of liquefied petroleum gas. It is also an ideal fuel for diesel engines, and compared to methanol fueled cars, there is no problem with cold starting of cars. Dimethyl ether is also one of the main raw materials for the production of low-carbon olefins in the future.HOW TO BUY FROM US
