Ethyl Bromide

 

(also bromoethane), C2H5Br, a colorless liquid with a weak ethereal odor. Ethyl bromide has a melting point of – 119°C, a boiling point of 38.3°C, and a density of 1.459 g/cm3 at 20°C. It is poorly soluble in water.

Ethyl bromide is produced from ethyl alcohol according to the reaction

C2H5OH + KBr + H2SO4 → C2H5Br + KHSO4 + H2O

It is used in organic synthesis for the introduction of the ethyl group, C2H5—. It is also used as a component of antiknock fluids in gasoline (see).

For alkyl halides and nitriles (Table 4, items 5 and 6), in vitro screening failed to detect toxicity, whereas they are positive for in vivo toxicity (except for volatile bromoethane and acetonitrile), but in the case of phenylenediamine derivatives and alkyl aldehydes (Table 4, items 7 and 8), the agreement between in vitro and in vivo results is higher.
