Beschreibung
It was firstly produced by nitric acid oxidation of cork (Latin suber) material and then from castor oil. The oxidation of ricinoleic acid produces, by splitting at the level of the double bond and at the level of the OH group, at the same time, suberic acid (octanedioic acid) and the next homologue azelaic acid. Suberic acid was used in the manufacture of alkyd resins and in the synthesis of polyamides leading to nylon.
Chemische Eigenschaften
off-white crystalline powder
Definition
ChEBI: An alpha,omega-dicarboxylic acid that is the 1,6-dicarboxy derivative of hexane.
Reaktionen
Suberic acid is an essential chemical widespread in softwood trees' trunk. Can there be reactions such as esterification, carboxylic acid halides, amidation and reduction in suberic acid, generation pyrolysis is heated. Its main application is to react with dibasic alcohol and diamine, produce polyester and polymeric amide, and also for organic synthesis.
l?uterung methode
Crystallise it from acetone. It sublimes at 300o without decomposition. [Beilstein 2 IV 2028.]
