WebApr 7, 2024 · As an example, the instructions are written to extract an aqueous solution three times using \(25 \: \text{mL}\) diethyl ether each time (\(3 \times 25 \: \text{mL}\) diethyl ether). A procedural summary of the first two extractions is in Figure 4.29. Figure 4.29: Two extractions when the organic layer is on the top. Extraction #1 WebMay 18, 2024 · The Boiling or Evaporation of Diethyl Ether. When we heat water, we see bubbles appear as the boiling point approaches. The water then "boils" vigorously as it is converted from the liquid phase to a gas. I realised recently that during an ether extraction of a product, a lot of ether had evaporated, as was evident from the mass balance.
