Uses and applications
What the substance is used for, by industry and function
Chiefly as an ethylating agent, as an accelerator in the sulfation of ethylene, in some sulfonations.
Chemical intermediate for ethyl derivatives of phenols, amines, and thiols and as an alkylating agent.
The principal uses are as an intermediate in dye manufacture, as an ethylating agent in pigment production, as a finishing agent in textile manufacture and as a dye-set agent in carbonless paper. Smaller applications are in agricultural chemicals, in household products, in the pharmaceutical and cosmetic industries, as a laboratory reagent, as an accelerator in the sulfation of ethylene and in some sulfonation processes.
Diethyl sulfate is primarily used as an ethylating agent, and also as an accelerator in the sulfation of ethylene and in some sulfonations. Diethyl sulfate is also a chemical intermediate for ethyl derivatives of phenols, amines, and thiols, and as an alkylating agent.
Industrial uses: Pigment, Intermediate, Softener and conditioner.

Pharmacology
Diethyl Sulfate is a colorless, corrosive, oily liquid that darkens with age and has a faint peppermint odor. Diethyl sulfate is mainly used as an ethylating agent in organic synthesis and in the dye and textile manufacturing. Exposure to this substance results in severe irritation to the eyes, skin and respiratory tract. It is a possible mutagen and is reasonably anticipated to be a human carcinogen based on evidence of carcinogenicity in experimental animals and may be associated with developing laryngeal cancer. (NCI05)
How it is made
Prepared from ethanol + sulfuric acid, by absorption of ethylene in sulfuric acid, from diethyl ether and fuming sulfuric acid.
