Description and Uses

Butyl ether (dibutyl ether) is a colorless, stable liquid, with a mild ether-like odor. It is immiscible with water, with a specific gravity of 0.8, which is lighter than water. Butyl ether is a moderate fire risk and will form explosive peroxides on aging. Flammable range is 1.5%–7.6% in air, with a boiling point of 286°F (141°C) and a flash point of 77°F (25°C). Ignition temperature is 382°F (194°C), and the vapor density is 4.5, which is heavier than air. In addition to flammability, butyl ether is toxic on prolonged inhalation. The four-digit UN identification number is 1149. The NFPA 704 designation is health 2, flammability 3, and reactivity 1. The primary use is as a solvent.

Dibutyl ether is used mainly as a solvent for organic materials such as resins, oils, hydrocarbons, esters, gums, and alkaloids. It is also used as an extracting agent in metal separation, as a reacting medium in organic synthesis processes, and as a solvent in teaching, research and analytical laboratories.
