Manufacture of Sebacic Acid by Pyrolysis of Castor Oil

Home » Technology » New Technologies » Chemicals Based Technologies »Sebacic Acid by Pyrolysis of Castor Oil


Castor oil is split to produce fatty acids which are subjected to alkali fusion. The products are neutralized to separate 2-octanol and other fatty acids. Sebacic acid is obtained on further acidification which separated and purified. Processing is simpler and cost effective


Sebacic acid esters are used as plastizers, a modifier for dimer acid based polyamides in the manufacture of Nylon 6, 10 and Nylon 10, 10 and also used in synlubes.
