Description
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.

Uses
Di-n-butyl ether is used as a solvent for Grignard, Witting and alkyl lithium reactions. It is also used as a solvent for oils and fats and some natural and synthetic resins. It is considered as a replacement for terathydofuran in organic synthesis due to its less water and peroxide and high boiling point. In the pharmaceutical industry, it is used in the manufacturing process of active pharmaceutical ingredient such as procarbazine and cefaclor. In addition to this, it is used as an important solvent for the application of the coating. Butyl 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. Solvent for hydrocarbons, fatty materials;
extracting agent used especially for separating met-
als, solvent purification, organic synthesis (reaction
medium).
