摘要: A 21-carbon aliphatic branched chain dicarboxylic acid and a 21-carbon lactone are produced by reacting fatty acid (which contains linoleic acid) with acrylic acid via iodine catalysis, and subsequently removing from the low monomer reaction product the resulting C-21 lactone via solvent extraction with acetonitrile and hexane or heptane. The reaction products are distilled to yield dicarboxylic acid and lactone of high purity.
