Chemische Eigenschaften
colourless liquid
Occurrence
Reported found in cabbage, sauerkraut, mustard, egg, chicken, beef, pork, beer (0.0002 to 0.0017 ppm), grape brandy (cognac, armagnac, weinbrand).
Verwenden
Diethyl sulfide may be used as an analytical standard for the determination of the analyte in wastewater, wines, and beer by gas chromatography (GC) based techniques.
Verwenden
Diethyl sulfide is used as a solvent for anhydrous mineral salts and in plating baths for coating metals with gold or silver. It is used as a flavoring agent. It is also used in the addition reaction with platinum dichloride to prepare platinum ethynyl dimers and polymers with pendant ferrocenyl group. Further, it is used in the preparation of triethylsulfoniuim ethylsulfate by reaction with sulfuric acid diethyl ester. In addition to this, it is used in the quantification procedure of volatile sulfur compounds by solid-phase microextraction.
Verwenden
Solvent for Anhydrous mineral salts; in plating baths for coating metals with gold or silver.
Definition
ChEBI: An ethyl sulfide compound having two ethyl groups attached to a sulfur atom.

Allgemeine Beschreibung
A colorless oily liquid with a garlic-like odor. Less dense than water. Flash point 20°F. Vapors heavier than air. May irritate skin and eyes. Used to make other chemicals.
Air & Water Reaktionen
Highly flammable. Slightly soluble in water.
Reaktivität anzeigen
Organosulfides, such as 1,1'-Thiobisethane, are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid.
Health Hazard
May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
Brandgefahr
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
Sicherheitsprofil
Mildly toxic by ingestion. A skin and eye irritant. A very dangerous fire hazard when exposed to heat, flame, or sparks; can react vigorously with oxidizers. Reacts with water, steam, acids, or acid fumes to produce toxic and flammable vapors. To fight fire, use water spray or mist, dry chemical, CO2, foam. When heated to decomposition it yields highly toxic fumes of SOx. See also SULFIDES.
läuterung methode
Wash the sulfide with aqueous 5% NaOH, then water, dry with CaCl2 and distil it from sodium. It can also be dried with MgSO4 or silica gel. Alternative purification is via the Hg(II) chloride complex [(Et)2S.2HgCl2] (see dimethyl sulfide). [Beilstein 1 IV 1394.]
