Description and Uses
Ethylene dibromide is a colorless nonflammable liquid or solid (below 10℃) with a sweet, chloroformlike odor. The minimum concentration detectable by odor is10 ppm. Molecular weight = 187.88; Specific gravity(H2O:1) = 2.17; Boiling point = 131℃; Freezing/Meltingpoint = 10℃; Relative vapor density (air = 1) = 6.5; Vaporpressure = 12 mmHg. Soluble in water
1,2-Dibromoethane (EDB) is used as a fumigant for grains, in antiknock gasolines, as asolvent, and in organic synthesis. Most of the uses of 1,2-dibromoethane have been stopped in the United States; however, it is still used as a fumigant for treatment of logs for termites and beetles, for the control of moths and beehives, and as a preparation for dyes and waxes.
