Brassylic acid: chemical intermediate from high erucic oils
1977
Carlson, K.D. | Sohns, V.E. | Perkins, R.B. Jr | Huffman, E.L.
Techniques and information derived from laboratory studies of a two-stage cleavage of erucic acid with ozone and oxygen have been translated to a small pilot-scale operation to produce brassylic acid (72-82% yield) of high purity (99%) with pelargonic acid as a coproduct. The initial ozonolysis phase is yield-limiting while the second stage oxidation of ozonolysis intermediates appears to be quantitative. A preliminary cost estimate has been prepared for production of polymer-grade brassylic acid from Crambe abyssinica seed oil. The effects of by-product credit and crambe oil cost on the net cost-to-make brassylic acid are illustrated.
