Sodium methoxide is a colorless solid, which hydrolyzes in contact with water, but is soluble in alcohols.
Sodium methoxide can be prepared by slowly and carefully adding metallic sodium to an excess of anhydrous methanol. The resulting sodium methoxide can be purified by recrystallizing it from solution.
CH3OH + Na → CH3ONa + ½ H2
Since this reaction produces hydrogen and lots of heat, it's best to perform it in an ice bath, best in an oxygen-less atmosphere, in a well ventilated area.
A more safe route involves the reaction of sodium hydroxide with anhydrous methanol, in the presence of a desiccator, such as molecular sieves. In a flask, add 200 ml of anhydrous methanol and 40 g of sodium hydroxide and begin stirring until it completely dissolves. After it dissolved, add 100 g of dried 3A molecular sieves. Seal the flask, mark the methanol level and wait a few days. After the level of the methanol no longer decreases, Filter the resulting solution and recrystallize the sodium methoxide. If the solution wasn't dried completely, simply change the sieves and repeat.
Application
