64-67-5 Usage
Health Hazard
May be fatal if inhaled, swallowed or absorbed through skin. Inhalation causes nausea and vomiting. Causes burns to skin and eyes. Ingestion may cause nausea, vomiting abdominal pain and collapse.
Reactivity Profile
The presence of moisture in a metal container of Diethyl sulfate caused the formation of sulfuric acid which reacts with the metal to release hydrogen which pressurized and exploded the container [Chem. Abst. 28:2908(1934)].
Purification Methods
Wash the ester with aqueous 3% Na2CO3 (to remove acidic material), then distilled water, dry (CaCl2), filter and distil it in a vacuum. It is an ethylating agent and blisters the skin. [Beilstein 1 IV 1236.]
Chemical Properties
colourless oily liquid
General Description
A clear colorless liquid with a peppermint odor. Burns, though may be difficult to ignite. Corrosive to metals and tissue.
Uses
Chiefly as an ethylating agent; as an accelerator in the sulfation of ethylene; in some sulfonations.
Air & Water Reactions
Highly flammable. Slowly reacts with water to form ethyl alcohol, a flammable liquid, and ethyl sulfate, with eventual conversion to sulfuric acid.
