NFPA 704

Diamond Hazard Value Description
Flammability   1 Materials that require considerable preheating, under all ambient temperature conditions, before ignition and combustion can occur. Includes some finely divided suspended solids that do not require heating before ignition can occur. Flash point at or above 93.3 °C (200 °F). (e.g. mineral oil, ammonia)
Instability   1 Normally stable, but can become unstable at elevated temperatures and pressures (e.g. propene)

Diethyl sulfate Chemical Properties,Uses,Production

Chemical Properties

colourless oily liquid


Chiefly as an ethylating agent; as an accelerator in the sulfation of ethylene; in some sulfonations.

General Description

A clear colorless liquid with a peppermint odor. Burns, though may be difficult to ignite. Corrosive to metals and tissue.

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.

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)].

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.

Safety Profile

Confirmed carcinogen with experimental carcinogenic and tumorigenic data. Poison by inhalation and subcutaneous routes. Moderately toxic by ingestion and sktn contact. A severe skin irritant. An experimental teratogen. Mutation data reported. Combustible when exposed to heat or flame; can react with oxidzing materials. Moisture causes liberation of H2SO4. Violent reaction with potassium tert-butoxide. Reacts violently with 3,8-dnitro-6-phenylphenanthridine + water. Reaction with iron + water forms explosive hydrogen gas. To fight fire, use alcohol foam, H2O foam, CO2, dry chemicals. When heated to decomposition it emits toxic fumes of SOx. See also SULFATES.

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.]
