Ether is slightly soluble in water and miscible with many organic solvents. Colorless volatile liquid with pleasant smell. The density is 0.7 147 g/cm3. The boiling point is 34.5℃. Freezing point-1 16.2℃. Flash point -45℃. Autoignition point 160℃. The refractive index is 1.3526. The explosion limit in air is 2.34-6. 15%. It is easy to form explosive peroxide and must be treated with sodium sulfate before distillation.

Salting out can be carried out by adding inorganic salts to the aqueous solution of ether. Flammable. In case of Mars, high temperature, oxidant, perchloric acid, chlorine, oxygen and ozone, there is danger of burning and explosion. It has an anesthetic effect on people. Concentrations exceeding 303g/m3 are life-threatening.

The role of ether

1, the effect of ether anesthesia

Ether can be used in surgery and is an anesthetic. It was once used as an anesthetic in surgery. Because of side effects, the patient has a long recovery period, but it is no longer used. It has a strong analgesic effect and can relax skeletal muscle. Now it has been eliminated.

2. Ether can be used in industry.

Ether can be used as a reagent in industry and can also cause explosion. In air, it is easy to oxidize with oxides and become peroxides. Once the peroxide is unstable, it is easy to explode, so it should be placed in a radiation-free place.

3. Some patients should use ether with caution.

If patients with acute and chronic respiratory diseases, diabetes and poor renal function can be avoided, ether vapor has high density, strong pungent smell, unstable chemical properties and many complications afterwards.
