CH 3 CH 2 OH + H 2 SO 4 → CH 3 CH 2 OSO 3 H + H 2 O. If the temperature exceeds 140 °C, the ethyl sulfate product tends to react with residual ethanol starting material, producing diethyl ether. If the temperature exceeds 170 °C in a considerable excess of sulfuric acid, the ethyl sulfate breaks down into ethylene and sulfuric acid. [12] [13]

The third in the series of color developing agents used in developing color films, commonly known as CD-3, is chemically known as N-[2-[(4-Amino-3-methylphenyl)ethylamino]ethyl]methanesulfonamide Sesquisulfate Monohydrate. [1]
In preparing ethyl esters of fatty acids, both equivalents of the ethyl electrophile are transferred, unlike the usual alkylation of phenoxides: [1] 2 RCO 2 Na + (C 2 H 5 O) 2 SO 2 → 2 RCO 2 C 2 H 5 + Na 2 SO 4. Both dimethyl sulfate and diethyl sulfate react with inorganic nucleophiles as well. For example, potassium iodide gives ethyl iodide.
Ethanethiol, commonly known as ethyl mercaptan, is an organosulfur compound with the formula CH 3 CH 2 SH. [5] It is a colorless liquid with a distinct odor. Abbreviated EtSH, it consists of an ethyl group (Et), CH 3 CH 2, attached to a thiol group, SH. Its structure parallels that of ethanol, but with sulfur in place of oxygen. The odor of ...
4 Et 2 O·BF 3 + 2 Et 2 O + 3 C 2 H 3 OCH 2 Cl → 3 [Et 3 O] + [BF 4] − + B(OCH(CH 2 Cl)CH 2 OEt) 3. where the Et stands for ethyl. The trimethyloxonium salt is available from dimethyl ether via an analogous route. [6] These salts do not have long shelf-lives at room temperature. They degrade by hydrolysis: [Et 3 O] + [BF 4] − + H 2 O → ...
tert-Butylthiol is the main ingredient in many gas odorant blends. [citation needed] It is always utilized as a blend of other compounds, typically dimethyl sulfide, methyl ethyl sulfide, tetrahydrothiophene or other mercaptans such as isopropyl mercaptan, sec-butyl mercaptan and/or n-butyl mercaptan, due to its rather high melting point of −0.5 °C (31.1 °F).
4-Ethylphenyl sulfate (4EPS) is a metabolite produced by gut bacteria, which can be toxic when present in large amounts. Elevated levels of this metabolite have been associated with some medical conditions including chronic kidney disease and autism .
