Diethyl ether, or simply ether, is an organic compound with the chemical formula (CH 3 CH 2) 2 O, sometimes abbreviated as Et 2 O. [ a ] It is a colourless, highly volatile , sweet-smelling ("ethereal odour"), extremely flammable liquid .
A cyclic ether and high-boiling solvent (b.p. 101.1 °C). Tetrahydrofuran (THF) A cyclic ether, one of the most polar simple ethers that is used as a solvent. Anisole (methoxybenzene) An aryl ether and a major constituent of the essential oil of anise seed. Crown ethers: Cyclic polyethers that are used as phase transfer catalysts. Polyethylene ...
The trends observed in their boiling points (figure 8) shows exactly the correlation expected, where sodium n-butoxide requires significantly more heat energy (higher temperature) to boil than n-butanol, which boils at a much higher temperature than diethyl ether. The heat energy required for a compound to change from liquid to gas is ...
Diethyl ether has a long history as a medical anesthetic; when starting fluid was mostly ether, a similar effect could be obtained using it. Use at the present time directly as an inhalant includes the effect of the petroleum solvents, which are more toxic as inhalants than diethyl ether. [7] [8]
An example of an ether is the solvent diethyl ether. [1] Halogenated ethers differ from other ethers because there are one or more halogen atoms—fluorine, chlorine, bromine, or iodine—as substituents on the carbon groups. . [2] Examples of commonly used halogenated ethers include isoflurane, sevofluorane and desflurane. [3]
The handling of this chemical may incur notable safety precautions. It is highly recommended that you seek the Material Safety Datasheet for this chemical from a reliable source such as SIRI, and follow its directions. MSDS for diethyl ether is available at Mallinckrodt Baker.
Several entrainers can be used for this specific process: benzene, pentane, cyclohexane, hexane, heptane, isooctane, acetone, and diethyl ether are all options as the mixture. [2] Of these benzene and cyclohexane have been used the most extensively, but since the identification of benzene as a carcinogen, toluene is used instead. [citation needed]
Good solvents are likely to be diethyl ether and hexane. (However, PE only dissolves at temperatures well above 100 °C.) (However, PE only dissolves at temperatures well above 100 °C.) Poly(styrene) has a solubility parameter of 9.1 cal 1/2 cm −3/2 , and thus ethyl acetate is likely to be a good solvent.
