Brief Overview

Diethyl sulfate is a colorless liquid with formula C4H10O4S. It has a peppermint odor with a melting point of about -25 ℃ and boiling point of 209.5 ℃ where it decomposes. When heated or mixed with hot water, irritant fumes is released. Diethyl sulfate does not dissolve in water, but is miscible with alcohol, ether and most polar organic solvents. Diethyl sulfate exists in the atmosphere in the gas phase. It will react with hydroxyl radical and has a short lifetime in the atmosphere where it will decompose into ethyl sulfate hydrogen sulfate and ethanol. Upon heating or mixing with hot water, diethyl sulfate will decompose into ethyl hydrogen sulfate and alcohol.

Manufacturing process

Diethyl sulfate is produced from ethylene and concentrated sulfuric acid. Ethylene gas is bubbled through a solution of concentrated sulfuric acid. Diethyl sulfate can also be produced by mixing concentrated sulfuric acid into a solution of ethyl alcohol or ethyl ether.
