General description

Diethylether, also known as ethyl ether or ether, is frequently used as a laboratory solvent. It is highly volatile, non-flammable, has limited solubility in water, and has high solubility in oil. Ethers are favored solvents for oils, fats, waxes, perfumes, dyes, resins, gums, and hydrocarbons. Additionally, it can be used as a fuel and to synthesize other chemical compounds. It is also employed as a solvent for Grignard synthesis.
