Ethylene Carbonate CAS 96-49-1

1. Ethylene Carbonate is primarily used as a high-purity aprotic solvent in lithium-ion and sodium batteries, where it dissociates lithium salts and maintains a stable dielectric constant for extended cycle life .
2. Ethylene Carbonate CAS 96-49-1 is a critical film-forming agent in battery electrolytes, creating a robust solid electrolyte interphase (SEI) on anodes and enabling high-voltage stability up to 5.5 V .
3. Ethylene Carbonate serves as a solvent in pharmaceuticals, cosmetics, semiconductor photoresist removal, and supercapacitors .

1. Store Ethylene Carbonate in a tightly sealed container in a cool, dry, well-ventilated place, as it is moisture-sensitive and should be kept upright to prevent leakage .
2. Keep Ethylene Carbonate CAS 96-49-1 strictly away from strong oxidizing agents, acids, bases, and reducing agents to prevent hazardous decomposition .
3. Handle Ethylene Carbonate using appropriate personal protective equipment including nitrile gloves and safety goggles, as it causes skin irritation (H315), serious eye irritation (H319), and may cause respiratory irritation (H335) .

1. Isolate the spill area, wear full protective equipment including self-contained breathing apparatus, and avoid dust formation when handling solid Ethylene Carbonate .
2. Sweep up spilled Ethylene Carbonate CAS 96-49-1 using non-sparking tools into sealed, labeled containers for disposal, and prevent entry into drains or waterways .
3. Personnel cleaning Ethylene Carbonate spills must use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide for fire extinguishing and dispose of waste through a licensed facility .

1. Ethylene Carbonate is classified with GHS signal word "Warning" and is harmful if swallowed (H302), causes skin and serious eye irritation (H315, H319), and may cause respiratory irritation (H335) .
2. Ethylene Carbonate CAS 96-49-1 may cause damage to organs through prolonged or repeated exposure (H373) and has an oral LD50 of 10 g/kg in rats .
3. Ethylene Carbonate is stable under recommended storage conditions with a melting point of 35-38°C, boiling point of 243-248°C, flash point of 143-152°C, and thermal decomposition produces toxic carbon oxides .
