WebOct 4, 2024 · The problem is, the drying agent is a Lewis acid. It sticks to lone pairs on the oxygen atoms in the water molecules. Unless the compound you are trying to extract is a hydrocarbon, chances are it contains oxygen atoms, too; most compounds in nature do. That means it sticks to the drying agent. WebApr 7, 2024 · The extraction is repeated two to three times, or perhaps more times if the compound has a low partition coefficient in the organic solvent. Figure 4.16 shows a diagram of an aqueous solution being extracted twice with diethyl ether. Diethyl ether has a density less than \(1 \: \text{g/mL}\), so is the top organic layer in the funnel.

Drying diethyl ether

WebDiethyl ether (CAS 60-29-7) is a component of starting fluids and is used as a solvent in the manufacture of synthetic dyes and plastics. Because of its characteristics diethyl ether was widely used in many countries as an anesthetic agent, but was then replaced by other substances in the 1960s. The main route of exposure is inhalation. It is particularly important as a solvent in the production of cellulose plastics such as cellulose acetate. Diethyl ether has a high cetane number of 85–96 and is used as a starting fluid, in combination with petroleum distillates for gasoline and diesel engines because of its high volatility and low flash point. Ether starting fluid is sold and used in c…
