Specification
The Ethyl sulfide with CAS registry number of 352-93-2 is also known as Diethyl sulfide. The IUPAC name is Ethylsulfanylethane. It belongs to product categories of Sulfide Flavor. Its EINECS registry number is 206-526-9. In addition, the formula is C4H10S and the molecular weight is 90.19. This chemical is a colourless liquid and should be sealed in cool place.
Physical properties about Ethyl sulfide are: (1)ACD/LogP: 1.95; (2)ACD/LogD (pH 5.5): 1.95; (3)ACD/LogD (pH 7.4): 1.95; (4)ACD/BCF (pH 5.5): 17.86; (5)ACD/BCF (pH 7.4): 17.86; (6)ACD/KOC (pH 5.5): 274.03; (7)ACD/KOC (pH 7.4): 274.03; (8)Index of Refraction: 1.439; (9)Molar Refractivity: 28.57 cm3; (10)Molar Volume: 108.5 cm3; (11)Surface Tension: 24.6 dyne/cm; (12)Density: 0.831 g/cm3; (13)Enthalpy of Vaporization: 31.77 kJ/mol; (14)Boiling Point: 94.4 °C at 760 mmHg; (15)Vapour Pressure: 54.2 mmHg at 25 °C.
Preparation of Ethyl sulfide: it is prepared by reaction of crude ethylsulfide. Firstly, mercury chloride is added to ethanol, then crude ethylsulfide is put into the mixture. Secondly, generated complex is refined by recrystallization and added to hydrochloric acid. At last, product is obtained by heating, washing and drying.
Uses of Ethyl sulfide: it is used to produce triethylsulfoniuim ethylsulfate by reaction with sulfuric acid diethyl ester. The reaction occurs with solvent acetonitrile and other condition of heating for 2.5 hours. The yield is about 85%. Besides, it is also used as a solvent for anhydrous minerals and in plating baths for gold and silver.
