1.It is mainly used as solvent of nitrocellulose, cellulose ether, synthetic resin and natural resin, intermediate of pesticide pyrethrin and drug phenobarbital.
2.In the instrument industry, it is used to make fixing paint and seal the cathode of electron tube.
1. Solvent: Because of its ability to dissolve a wide variety of substances, it is often used as a solvent in organic synthesis and in the formulation of paints, coatings, and adhesives.
2. Chemical intermediate: Diethyl carbonate is a raw material for the synthesis of various chemicals (including pharmaceuticals and agricultural chemicals).
3. Electrolyte in batteries: It is used as a component of lithium-ion battery electrolyte, helping to improve the performance and stability of the battery.
4. Plasticizer: Diethyl carbonate can be used as a plasticizer in the production of plastics and polymers to enhance their flexibility and durability.
5. Fuel Additive: It can also be used as an additive in fuel to improve combustion performance.
Diethyl carbonate is colorless transparent liquid with slightly pungent odor. It is insoluble in water, soluble in alcohol, ether and other organic solvents.
Stored at a dry, shady, ventilated place.
1. Container: Store diethyl carbonate in airtight containers made of compatible materials such as glass or certain plastics. Make sure the container is clearly labeled.
2. Temperature: Store in a cool and dry place away from direct sunlight and heat sources. Recommended storage temperature is usually below 25°C (77°F).
3. Ventilation: Store in a well-ventilated area to prevent accumulation of vapors, which may be flammable.
4. Incompatibility: Avoid storing diethyl carbonate near strong oxidants, acids or bases as it may react with these substances.
5. Fire prevention: Diethyl carbonate is flammable and should be kept away from open flames, sparks and other sources of ignition. Appropriate fire extinguishing equipment should be available nearby.
6. Disposal: Dispose of any waste or unused diethyl carbonate in accordance with local regulations.
1. Regulatory Compliance: Ensure compliance with local, national, and international regulations regarding the transportation of dangerous goods. This includes following guidelines set by organizations such as the U.S. Department of Transportation (DOT) or the International Air Transport Association (IATA) for air shipments.
2. Appropriate Packaging: Use appropriate packaging materials that are compatible with diethyl carbonate. The container should be leakproof and made of materials that can withstand the chemical properties of diethyl carbonate.
3. Label: Clearly label the packaging with correct hazard symbols and handling instructions. This includes indicating that the contents are flammable and may be harmful if inhaled or swallowed.
4. Temperature Control: Ensure the transportation environment is controlled to avoid exposure to extreme temperatures, which may affect the stability of diethyl carbonate.
5. Avoid spills: Take precautions during loading, unloading and transport to prevent spills. This may include the use of secondary containment.
6. Training: Ensure that personnel involved in the transportation process are trained in handling hazardous materials and understand the risks associated with diethyl carbonate.
7. Emergency Procedures: Develop emergency response procedures in case of spills or accidents during transportation. This includes having appropriate spill kits and personal protective equipment (PPE) ready.
Yes, diethyl carbonate is considered hazardous. Here are some key points about its hazards:
1. Flammability: Diethyl carbonate is a flammable liquid that will ignite easily if exposed to heat, sparks or open flames. It has a flash point of approximately 26°C (79°F), which means it can form flammable vapors at relatively low temperatures.
2. Health Hazard: Exposure to diethyl carbonate may irritate the skin, eyes, and respiratory system. Inhalation of vapors may cause dizziness, headache, or breathing problems. Prolonged or repeated exposure may cause more serious health effects.
3. Environmental Hazards: Diethyl carbonate may be harmful to aquatic life and may cause long-term adverse effects to the environment. It should be handled and disposed of properly to minimize impact on the environment.
4. Regulatory Classification: Diethyl carbonate is classified as a hazardous substance under various regulations, which may include the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) and local regulations on chemical safety.
