ECHEMI Editorial Reference

Dimethyl carbonate (DMC) is an organic compound with the formula OC(OCH3)2. It is a colourless, flammable liquid. It is classified as a carbonate ester. This compound has found use as a methylating agent and more recently as a solvent that is exempt from the restrictions placed on most volatile organic compounds (VOCs) in the US. Dimethyl carbonate is often considered to be a green reagent.
Dimethyl carbonate appears as a clear, colorless liquid with a pleasant odor. Denser than water and slightly soluble in water. Vapors are heavier than air. Used to make other chemicals and as a special purpose solvent.|Liquid|COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR.
Dimethyl carbonate appears as a clear, colorless liquid with a pleasant odor. Denser than water and slightly soluble in water. Vapors are heavier than air. Used to make other chemicals and as a special purpose solvent.|Dimethyl carbonate is a carbonate ester that is carbonic acid in which both hydrogens are replaced by methyl groups. A flammable, colourless liquid (m.p. 2-4℃, b.p. 90℃) with a characterstic ester-like odour, it is used as a 'green' methylating agent and as a solvent. It has a role as a solvent and a reagent.

Air and Water Reactions:

Highly flammable. Slightly soluble in water.

Reactive Group:

Esters, Sulfate Esters, Phosphate Esters, Thiophosphate Esters, and Borate Esters

Reactivity Alerts:

Highly Flammable

Reactivity Profile:

DIMETHYL CARBONATE reacts with acids to liberate heat along with methanol and carbon dioxide. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction with caustic solutions. Flammable hydrogen is generated by mixing with alkali metals and hydrides.

Autoignition Temperature:

458 °C

Physical Dangers:

The vapour is heavier than air and may travel along the ground; distant ignition possible. The vapour mixes well with air, explosive mixtures are easily formed.

Heat of Vaporization:

3.8363X10+7 J/Kmol at 273.15 K

Critical Temperature & Pressure:

Critical temperature: 548.00 K; Critical pressure: 4.5X10+6 Pa

Handling and Storage

Precautions for safe handling

NO open flames, NO sparks and NO smoking. NO contact with oxidizing agents. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

Conditions for safe storage, including any incompatibilities

Fireproof. Separated from strong oxidants. Well closed. Store in an area without drain or sewer access.Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Air sensitive.
