Sodium ethoxide (C2H5ONa) is a white to yellowish powder, which readily hydrolyzes in water and moist air.
Sodium ethoxide readily hydrolyzes in contact with water, releasing lots of heat.
Sodium ethoxide is a colorless solid, which reacts with water.
Sodium ethoxide is sold by chemical suppliers.
- Make esters
Sodium ethoxide is caustic and contact with skin will cause chemical burns. Reaction with water will give ethanol and lots of heat, which may ignite the alcohol vapors.
Sodium ethoxide should be stored in air-tight containers, or in a desiccator. Schlenk flasks are a good choice.
Sodium ethoxide can be neutralized by dissolving it in large amounts of water slowly, then neutralize the resulting sodium hydroxide. Sodium bicarbonate can be used.
