Dodecanedioic acid (DDDA) is a dicarboxylic acid mainly used in antiseptics, top-grade coatings, painting materials, corrosion inhibitors, surfactants, and engineering plastics such as nylon 612.[1]

Experimental work with dodecanedioic acid in type 2 diabetic patients has demonstrated that IV infusion helps to maintain normal blood sugar and energy levels without increasing the blood glucose load in the process.[2]

Production

Synthetic production

DDDA is typically produced through two methods. It has traditionally been produced from butadiene using a multi-step chemical process.[3] Butadiene is first converted to cyclododecatriene through a cyclotrimerization process.[4]

Cyclododecatriene (1) is converted to dodecanedioic acid (4) by hydrogenation to cyclododecane (2) followed by air oxidation in the presence of boric acid at elevated temperatures to a mixture of the alcohol (3a) and the ketone (3b). In the final step, this mixture oxidized further by nitric acid.

Biotech production

A biotechnology is used to convert paraffin wax into DDDA with a special strain of Candida tropicalis yeast in a multi-step process.[5] Verdezyne has created a method to use plant-oil sourced feedstocks, which makes it the only producer using renewable feedstocks for DDDA.[3]
