EMEROX® Polyols are based on renewable azelaic (C9 dibasic) acids produced via Emery Oleochemicals’ ozonolysis technology as shown in the figure below. Emery Oleochemicals’ ozonolysis technology and process was developed in the 1950s to produce azelaic and pelargonic acid (C9 dibasic and C9 monobasic acid respectively) from oleic acid and is a well-established large-scale commercial production process.
