General description
Sodium hydroxide (caustic soda) is an inorganic source of hydroxide ions that can be used to alkylate phenols, alcohols, aldehydes, and ketones. NaOH can also be used to convert amides into amines, to produce dichlorocarbenes, and in saponification of carboxylic acid derivatives.
