Properties

Sodium ethoxide is one of the typical alkoxides. It is nontoxic, strongly alkaline, easily hygroscopic, and easily soluble in polar solvents (such as ethanol). Its ethanol solution is stable in nature. It decomposes when exposed to air, and its color gradually darkens after long-term storage. When it meets with water, it decomposes into sodium hydroxide and ethanol. Sodium ethoxide is very basic, which is often used in organic synthesis to remove the active hydrogen of organic compounds (such as the condensation reaction of clarson ester and the synthesis of malonate), and also used in the synthesis of pesticides. Sodium ethoxide can be used to extract the ester α Hydrogen can form enol structure, and nucleophilic addition reaction with carbonyl group of ester (called transesterification).
