For ethylene carbonate: To transfer ethylene carbonate, i) if the container is unopened, put as-received container in a convection oven at 65 ºC for about 3 hours (could be longer if necessary) until it melts (you should be able to hear liquid flowing when you shake the container carefully).
How do you make ethylene carbonate?
Ethylene carbonate is produced by the reaction between ethylene oxide and carbon dioxide. The reaction is catalyzed by a variety of cations and complexes: (CH2)2O + CO2 → (CH2O)2CO.
What is diethyl carbonate used for?
Diethyl carbonate (DEC) is a well-known linear organic carbonate that has wide applications. Besides its use as a fuel additive, DEC is an excellent electrolyte for lithium ion batteries and is used for the production of polycarbonates, which are globally used engineering plastics.
How do you store ethylene carbonate?
Avoid ingestion and inhalation. Storage: Store in a cool, dry place. Store in a tightly closed container. OSHA Vacated PELs: Ethylene Carbonate: No OSHA Vacated PELs are listed for this chemical.
What is ethylene carbonate used for?
As ethylene carbonate is a highly polar solvent and dissolves large amount of electrolyte, it is mainly used in lithium batteries electrolyte solution. It can also readily dissolve polymers leading to use as a release agent and detergent.
How is diethyl carbonate made?
Production. It can be made by reacting phosgene with ethanol, producing hydrogen chloride as a byproduct. It can also be synthesized directly from carbon dioxide and ethanol using various methods, and via oxidative carbonylation with carbon monoxide. Another method is transesterification from dimethyl carbonate.
What chemical is ec?
Ethylene carbonate (sometimes abbreviated EC) is the organic compound with the formula (CH2O)2CO. It is classified as the cyclic carbonate ester of ethylene glycol and carbonic acid.
Is ethylene carbonate soluble in water?
The water solubility of ethylene carbonate was determined to be 778 g/L (very soluble) following a GLP study conducted in accordance with EU test method A.
Is ethylene carbonate toxic?
Ingestion: May cause irritation of the digestive tract. May cause kidney damage. Inhalation: May cause respiratory tract irritation. May be harmful if inhaled.
How do you use ethylene carbonate?
Applications. Ethylene carbonate is used as a polar solvent with a molecular dipole moment of 4.9 D, only 0.1 D lower than that of propylene carbonate. It can be used as a high permittivity component of electrolytes in lithium batteries and lithium-ion batteries.
How do you store calcium carbonate in a lab?
Storage: Store in a cool, dry place. Store in a tightly closed container. 15 mg/m3 TWA (total dust); 5 mg/m3 TWA (respirable fraction) (listed under Calcium carbonate).
