Malonic acid Specification

  Malonic acid with cas registry number of 141-82-2 is  is a carboxylic acid, also called for AI3-15375 ; Carboxyacetic acid ; Dicarboxymethane ; Kyselina malonova ; Kyselina malonova [Czech] ; MALONIC ACID ; Methanedicarboxylic acid ; NSC 8124 ; Propanedioic acid ; USAF EK-695 . It can be prepared in this way: Sodium carbonate generates the sodium salt which is then reacted with sodium cyanide to provide the cyano acetic acid salt via a nucleophilic substitution. The nitrile group can be hydrolyzed with sodium hydroxide to sodium malonate and acidification affords malonic acid.
