Sodium ethoxide (C2H5ONa) is a white to yellowish powder, which readily hydrolyzes in water.
Contents
Properties
Chemical
Sodium ethoxide readily hydrolyzes in contact with water, releasing lots of heat.
Physical
Sodium ethoxide is a colorless solid, which reacts with water.
Availability
It is sold by chemical suppliers.
Preparation
Sodium ethoxide can be prepared by adding sodium metal to anhydrous ethanol.
Projects
- Make esters
Handling
Safety
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.
Storage
Sodium ethoxide should be stored in air-tight containers, or in a desiccator. Schlenk flasks are a good choice.
Disposal
Sodium ethoxide can be neutralized by dissolving it in large amounts of water slowly, then neutralize the resulting sodium hydroxide.
