Diethyl carbonate Usage And Synthesis
Chemical Propertiescolourless liquid with a mild odour
UsesSolvent for nitrocellulose; manufacture of radio tubes; fixing rare earths to cathode elements.
General DescriptionA 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 ReactionsHighly flammable. Insoluble in water.
Reactivity ProfileDiethyl 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 HazardHigh vapor concentrations can cause headache, irritation of eyes and respiratory tract, dizziness, nausea, weakness, loss of consciousness.
Purification MethodsWash 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.]
