Anwendungen & Verwendung
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.
