Process for making a dicarboxylic acid

A 21-carbon aliphatic branched chain dicarboxylic acid is produced by reacting pre-conjugated fatty acid (which contains linoleic acid) with acrylic acid at a temperature between 180 DEG C. and 300 DEG C. No catalyst or solvent is necessary for the reaction to occur. The reaction product is subseque...

Summary:A 21-carbon aliphatic branched chain dicarboxylic acid is produced by reacting pre-conjugated fatty acid (which contains linoleic acid) with acrylic acid at a temperature between 180 DEG C. and 300 DEG C. No catalyst or solvent is necessary for the reaction to occur. The reaction product is subsequently distilled to yield high purity dicarboxylic acid.
