Uses
Different sources of media describe the Uses of 352-93-2 differently. You can refer to the following data:
1. 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.
2. 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.
3. Solvent for Anhydrous mineral salts; in plating baths for coating metals with gold or silver.
Definition

General Description
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 Reactions
Highly flammable. Slightly soluble in water.
Reactivity Profile
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.
Fire Hazard
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.
Safety Profile
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.
Purification Methods
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.]
Check Digit Verification of cas no
The CAS Registry Mumber 352-93-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,5 and 2 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 352-93:
(5*3)+(4*5)+(3*2)+(2*9)+(1*3)=62
62 % 10 = 2
So 352-93-2 is a valid CAS Registry Number.

Page/Page column 2, (2008/06/13)
In the photochemical synthetic process in semi-continuous mode according to the invention, a reactor comprising two zones is used, the radiating portion of the lamp(s) being totally immersed in a first zone which is completely filled with reaction medium and spills off via an overflow into a second zone whose volume is sufficient to contain the volume of reaction medium originating from the first zone and corresponding substantially to the volume of the reagent(s) gradually introduced.
