Name: Ethylene Carbonate
Chemical Formula: C3H4O3
CAS Number: 96-49-1
Usage: Found in lithium-ion battery electrolytes, acts as a solvent in plastic and detergent manufacturing, and appears in some consumer polishes.
Appearance: White, odorless, crystalline solid at room temperature, melts near 34°C, mixes well with water and organic solvents, giving it versatility.
Classification: Irritant—touching it can lead to moderate skin and eye discomfort, breathing in dust has been known to cause coughing, and it sometimes brings mild headaches.
Health Hazards: Skin and eye exposure favors redness or burning, too much inhalation makes breathing uncomfortable, and chronic overexposure can stress the kidneys or liver.
Environmental Hazards: Too much released in soil or water harms aquatic life.
Fire Hazards: Combusts to create irritating vapors and possibly carbon monoxide.
Main Component: Ethylene Carbonate—usually found in high purity in technical and laboratory use.
Impurities: Trace levels of ethylene glycol or water—these rarely change the hazard rating but might cause formation of acidic byproducts if left out in the open or mixed with contaminating agents.
Skin Contact: Wash off using soap and flowing water. Even small amounts left behind cause itching or irritation, so a definite soak and thorough cleaning is important.
Eye Contact: Rinse eyes for at least 10-15 minutes with clean water, making sure to hold the eyelid open. Use gentle motions to keep particles from causing more damage.
Inhalation: Move to fresh air to avoid more exposure. If severe coughing or shortness of breath sets in, seek medical care.
Ingestion: Rinse the mouth, drink a moderate amount of water, avoid vomiting, and head to a hospital. It irritates the stomach lining.
Suitable Extinguishing Media: Use water spray, dry chemical powder, or foam—never use a direct water jet because it spreads the powder.
Specific Hazards: Burning releases nasty fumes including carbon dioxide, carbon monoxide, and sometimes phosgene. Keep clear from smoke exposure.
Firefighter Protection: Wear full gear, plus a respirator, since toxic gases can cause acute breathing problems even with one small fire.
Personal Precautions: Throw on gloves, splash goggles, and a mask to block breathing in loose dust.
Environmental Precautions: Prevent it from flowing into drains or water bodies—if it hits water systems in large amounts, local wildlife can pay the price.
Cleanup Procedures: Sweep up without raising dust. Scoop into containers for safe disposal. Ventilate the area.
Safe Handling: Practice careful transfer—gentle movements, closed systems, and good ventilation. Dust floating in the air signals poor process management.
Storage: Park it away from heat, sunlight, and moisture, inside sealed, labeled containers. Secure storage cuts down on accidental exposure and keeps the worksite safe.
Engineering Controls: Ventilation counts for a lot—local exhaust or fume hoods keep particles and vapors out of the breathing air.
Personal Protection: Wear chemical-resistant gloves, safety glasses, and a dust mask or respirator. Change out contaminated clothing and wash up before eating or taking breaks.
Exposure Limits: No strict government limits exist for most places, but any lingering odor or dust cloud signals too much exposure.
Form: Crystalline solid
Boiling Point: Above 240°C
Melting Point: Around 34°C
Solubility: Dissolves in water and most organics
Vapor Pressure: Very low at room temperature
Odor: Nearly none
Chemical Stability: Remains quite stable when dry and cool—trouble starts under direct sunlight or in wet environments.
Reactivity: Reacts with strong acids or bases, decomposes if heated hard enough, making sure that nobody should ever cook or mix it unless trained and equipped.
Hazardous Decomposition: Churns out nasty fumes—carbon oxides and possibly trace phosgene—these push the need for good ventilation and careful disposal.
Inhalation Effects: At high doses, brings on coughing, nose irritation, and sore throats; long-term lungs may suffer.
Skin Effects: Redness, stinging, or dryness can result—protective gloves limit all these problems.
Eye Effects: Direct contact brings pain, watering, and possible blurry vision until the substance is washed out.
Ingestion: Upset stomach, burning sensation, and vomiting can develop. At heavy doses, kidney and liver may bear some of the toxic load.
Chronic Toxicity: No definitive data proving cancer or reproductive risk, but evidence supports declining health from regular overexposure.
Aquatic Impact: Large spills overwhelm aquatic habitats, affecting fish and smaller water-based life.
Persistence: Breaks down slowly in the environment; careful disposal stops it from leaking into soil or rivers.
Bioaccumulation: Not likely to build up in most organisms, but local spills can cause sudden trouble.
Waste Handling: Collect for chemical disposal, working with local or national waste guidelines. Leaking into regular drainage risks water pollution fines and environmental cleanup.
Packing: Use sturdy, labeled chemical drums, keeping incompatible chemicals apart. Reporting spills always protects from regulatory trouble and environmental damage.
Road and Rail: Move under “Chemical—Not Otherwise Specified,” make sure tanks or barrels stay secured, and pay attention to local transit regulations.
Sea and Air: Make sure shipping paperwork is accurate so receiving ports and airports catch any errors quickly—if spilled in transit, it counts as a reportable event.
Occupational Safety: Agencies like OSHA and EU REACH classify it as hazardous, so workplaces must track handling and worker exposure.
Environmental Law: Releases above certain volumes must get reported under national chemical release guidelines.
Labeling: Basic hazard symbols and risk statements go on every container, so anyone grabbing a drum or bottle can make smart, informed choices.
