Application of Sodium ethoxide
Sodium ethoxide is commonly used in the Claisen condensation and malonic ester synthesis. Sodium ethoxide may either deprotonate the a-position of an ester molecule, forming an enolate, or the ester molecule may undergo a nucleophilic substitution called transesterification. If the starting material is an ethyl ester, trans-esterification is irrelevant since the product is identical to the starting material. In practice, the alcohol/alkoxide solvating mixture must match the alkoxy components of the reacting esters to minimize the number of different products.
Many alkoxides are prepared by salt metathesis from sodium ethoxide.
1. Ethoxylate agent,as well as a coagulant and reductant for organic synthesis,pharmaceuticals and pesticides synthesis;
2. Pharmaceutical products used sodium ethoxide are: phenobarbital, butazodine, primidone,methyldopa,tetracaine hydrochloride, eprazinone,aminopterin,pyrimethamine,horse ampicillin etc.
