Diethyl carbonate is used as a solvent

Diethyl carbonate is a carbonate ester of Diethyl carbonateand ethanol with the formula OC(OCH2CH3)2. At room temperature diethyl carbonate is a clear liquid with a low flash point. It is colourless liquid with a mild odour with Molecular Weight is 118.13. Diethyl carbonate has the synonyms:Ethyl carbonate or Carbonic acid. The CAS Registry Number is 105-58-8.

It is negligible, stable, flammable, incompatible with strong acids, strong bases, reducing agents, oxidizing agents. Protect from moisture. It should be stored in flammables area. Diethyl carbonate can be made by reacting phosgene with ethanol, producing hydrogen chloride as a byproduct. This reaction is the base of why ethanol is added to chloroform in a 1% quantity by mass.
2CH3CH2OH + COCl2 → OC(OCH2CH3)2 + 2HCl

Diethyl carbonate is used as a solvent such as in erythromycin intramuscular injections. It can be used as a component of electrolytes in lithium batteries. Diethyl Carbonate(CAS NO:105-58-8) is a solvent of both extraction and reaction used in many industries; pharmaceuticals; agrochemicals; hydrocarbon refinery; paint and coatings and fragrances; It is used as a methylation and carbonylation agent in organic synthesis. It can be used as fuel and lube additive.

Diethyl carbonate is a carbon-containing dibasic acid which has two acidic hydrogen atoms in the same molecule. The other common example of dibasic acid is sulfuric acid (H2SO4). Diethyl carbonateis formed in solution when its anhydride is dissolved in water, existing only in equilibrium. The equilibrium is important for organisms to perform certain vital functions. The body fluids must maintain a constant pH. For example, blood must maintain a pH of close to 7.4 in order to carry oxygen from the lungs to cells. 

Diethyl carbonate has two acidic hydrogens and can lose one or two protons. The presence of pure Diethyl carbonateis not possible as even a single molecule of water causes the Diethyl carbonateto revert to carbon dioxide and water fairly quickly. Pure Diethyl carbonatecan be found if there is no water absolutely. 

Diethyl carbonate itself is a stronger acid than acetic acid or formic acid due to the influence of the electronegative oxygen substituent. Considering the equilibrium constant, however, the majority of the carbon dioxide is not converted into Diethyl carbonateand so such solutions are fairly weak. 

Diethyl carbonate forms two series of salts when combined with positive or basic atoms or radicals; the hydrogencarbonate which contain the hydrogencarbonate ion HCO3- formed when the first proton is removed and the carbonate which contain the carbonate ion, CO32- formed when the second proton is removed.
