Read： 453 Time：19months ago Source：Transform the World with Simplicity

Dimethyl carbonate (DMC) is a common chemical raw material, widely used in pesticides, pharmaceuticals, fuels, solvents and other fields. Due to its flammable, explosive and toxic properties, it is necessary to strictly comply with relevant safety regulations during storage and transportation. This article will detail the safe storage and transportation specifications of dimethyl carbonate.

1. the physical and chemical properties of dimethyl carbonate

dimethyl carbonate is a colorless transparent liquid with pungent odor. Its molecular formula is C3H6O3 and its molecular weight is 90.07. Dimethyl carbonate is insoluble in water, but miscible with organic solvents such as alcohols, ethers, ketones, etc. It is a polar solvent and has a strong ability to dissolve.

2. the harmful
of dimethyl carbonate
the harm of dimethyl carbonate to the human body is mainly manifested in the stimulation of the eyes, skin and respiratory system, as well as the anesthetic effect on the central nervous system. Prolonged exposure to dimethyl carbonate may cause dizziness, headache, nausea, vomiting and other symptoms. In addition, dimethyl carbonate also has the characteristics of flammable and explosive, encounter fire or high temperature may cause fire or explosion.

3. the safety of dimethyl carbonate storage specifications

1. The storage place should choose a cool, ventilated and dry place, away from open flames, heat sources and direct sunlight.
2. The storage container shall be a special stainless steel or carbon steel container, and shall be inspected and maintained regularly to ensure that the container is intact.
3. The storage area shall be equipped with corresponding fire-fighting facilities and equipment, such as fire extinguishers and fire hydrants, and regular drills and training shall be conducted to improve the fire safety awareness of employees.
4. During the storage process, the storage amount of dimethyl carbonate should be strictly controlled to avoid safety accidents caused by excessive storage.

4. of dimethyl carbonate safety transport specification

1. transport vehicles should comply with the relevant standards and regulations, with fire, explosion, anti-static and other safety facilities.
2. During transportation, the vehicle speed should be kept stable, and operations such as sudden braking and sharp turns should be avoided to reduce impact and friction during transportation.
3. During transportation, keep away from open flames and high temperature areas, and avoid direct sunlight and exposure to the sun.
4. Transportation personnel should be professionally trained to understand the nature of dimethyl carbonate and transportation safety knowledge to ensure safety during transportation.

1. In case of leakage of dimethyl carbonate, start the emergency plan immediately and organize professionals to deal with it.
2. A warning line shall be set up in the leakage area to prohibit irrelevant personnel from entering, and ventilation measures shall be taken to reduce the gas concentration in the leakage area.
3. For a small amount of leakage, sand, dry lime or soda ash can be mixed for treatment; for a large amount of leakage, a special pump or appliance should be used to recover to a special container.
4. Special protective equipment, such as protective gloves and protective glasses, should be used when dealing with leakage to avoid direct contact with dimethyl carbonate.

In short, dimethyl carbonate is a common raw material for chemical production, and its safe storage and transportation are very important. In the actual production process, the relevant safety regulations should be strictly observed to ensure the safety and reliability of the storage and transportation of dimethyl carbonate. At the same time, the safety training and education of employees should be strengthened, and the safety awareness and operation skills of employees should be improved to ensure the safety and stability of the production process.
