Diethyl carbonate Chemical Properties,Uses,Production

Chemical Properties

colourless liquid with a mild odour

Uses

Solvent for nitrocellulose; manufacture of radio tubes; fixing rare earths to cathode elements.

Production Methods

Manufacturing steps: (a) reacting chlorine and carbon monoxide to produce (COCl2); (b) reacting phosgene with ethyl alcohol to make ethyl chlorocarbonate (ClCO2C2H5); (c) reacting ethyl chlorocarbonate with anhydrous ethyl alcohol to produce diethyl carbonate.

Synthesis Reference(s)

General Description

A colorless liquid with a mild pleasant odor. Diethyl carbonate is slightly less dense than water and insoluble in water. Hence floats on water. Flash point 77°F. Vapors are heavier than air. When heated to high temperatures Diethyl carbonate may emit acrid smoke. Used as a solvent.

Air & Water Reactions

Highly flammable. Insoluble in water.

Reactivity Profile

Diethyl carbonate reacts with acids to liberate heat along with ethanol 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.

Health Hazard

High vapor concentrations can cause headache, irritation of eyes and respiratory tract, dizziness, nausea, weakness, loss of consciousness.

Chemical Reactivity

Reactivity with Water Too slow to be hazardous; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

Safety Profile

Wdly toxic by subcutaneous route. Questionable carcinogen with experimental tumorigenic and teratogenic data. A dangerous fire hazard when exposed to heat or flame; can react with oxidizing materials. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and fumes. See also ANHYDRIDES.

Carcinogenicity

A study using male and female mice treated with 0, 50, 250, or 1000 ppm (0–140 mg/kg/day) diethyl carbonate in drinking water indicated no carcinogenic effects.

Purification Methods

Wash the ester (100mL) with an aqueous 10% Na2CO3 (20mL) solution, saturated CaCl2 (20mL), then water (30mL). After drying by standing over solid CaCl2 for 1hour (note that prolonged contact should be avoided because slow combination with CaCl2 occurs), it should be fractionally distilled. Also dry it over MgSO4 and distil it. [Beilstein 3 H 5, 3 I 4, 3 II 4, 3 III 5, 3 IV 5.]
