Bromoethane CAS#74-96-4

Bromoethane is a colorless, volatile, flammable liquid. When exposed to air and light, it turns yellow. It has an ethereal odor and somewhat burning taste. Bromoethane has a specific gravity of 1.4505 between 4° and 25°C, a boiling point of 38.4°C, a melting point of -119°C, and a vapor pressure of 475 mm mercury at 25°C. It is 0.91% (w/w) soluble in water at 20°C and is miscible with ethanol, ethyl ether, chloroform, and other organic solvents. It has a flash point of -20°C (closed cup). The autoignition temperature is 511°C. The flammable limits in air are between 6.7570 and 11.25%. Although bromoethane is relatively stable, when heated to decomposition it emits highly toxic fumes of bromine and hydrobromide; it can react with oxidizing materials (ITII, 1979; Sittig, 1979; Torkelson and Rowe, 1981; Merck, 1983; Sax, 1984).

Product Application of Bromoethane CAS#74-96-4

Bromoethane is an alkylating agent primarily used as a chemical intermediate in organic synthesis, in the manufacture of pharmaceuticals, and for the ethylation of gasoline. To a lesser extent, it has been used as a fruit and grain fumigant, refrigerant, and solvent. Although proposed occasionally as a general anesthetic in the earlier part of this century, it has not been used to any extent for this purpose (Sayers et al., 1929; Abreu et al., 1939; ITII, 1979; Sittig, 1979; Torkelson and Rowe, 1981;Merck, 1983).
